Industry Intel

By Ian Moyse, EMEA Channel Director

Recent studies demonstrate that upwards of 25% of Internet bandwidth in an office are consumed by employees misusing the internet. According to Gartner, the average growth of business email volume is 30% annually, with the average size of the email content growing in parallel. Add to this the growth of Web misuse from streaming media, downloads, file sharing, social networking, and spam, and it becomes pretty clear that the mismanaged cost to business of non-work-related Internet use is already bad and getting worse.

There are plenty of examples, including employees wasting more than two hours a day on recreational computer activities (according to a survey fielded by AOL & Salary.com) and that, according to an IDC report, “30% – 40% of Internet use in the workplace is unrelated to business.”

Studies and surveys such as these typically focus only on lost productivity — and there’s no doubt that’s bad enough. But they rarely discuss the significant hidden financial impact of bandwidth wastage from these activities.

As 2010 winds down, I wanted to pull out the crystal ball and talk for a moment about where the security industry seems to be heading in the coming year, and where we anticipate threats and targets.

Mobile platforms: If you’re reading this, there’s a good chance you have either an iPhone, an Android phone, or a Blackberry in your pocket, case, or on your desk right now. If that’s true, then the data on that device is the next big target for criminals, and the newest front in the war on cybercrime. Users have embraced the advantages of mobile platforms, and even though IT admins may officially consider some or all of them “unsupported” in some organizations, you can’t abandon users who will choose convenience over strict IT policy. I predict that mobile platforms will continue to grow at a rapid pace, and we’ll soon reach the threshold level where malware creators start to take notice in significant numbers. IT admins should embrace these new platforms, and take steps to protect users who insist upon having them, even though doing so may make their work harder.

Social engineering: Whether you use a single PC at home, or manage a network of 25,000 laptops and desktops at work, social engineering scams have become so convincing that it’s a wonder IT admins ever get a good night’s rest.

It doesn’t matter how comprehensive your patch and update schedule is — when a sufficiently convincing spam email reaches a gullible employee, all bets are off. With targeted attacks becoming more common, the best defense against this threat continues to be education. Every user, from the newest administrative assistant to the C-level executives, needs training in identifying and avoiding fraudulent email and other messages, harmful file attachments, and Internet behavior that can lead to trouble.

Cloud vs. Desktop: We’ve seen demand for cloud-based services increasing across all segments of the business. In small and medium-sized businesses, we’re continuing to see strong demand for cloud-based solutions, and we expect that to continue next year. Overworked admins like the ease of administration and the performance benefits of cloud security services. And for the first time, we’re seeing consumers getting interested in the advantages the cloud brings to PC protection, including the speed that updates make it to the user of an infected computer.

At the larger end of the enterprise business segment, IT administrators must juggle the requirements of government regulations with the performance advantages that cloud services have to offer. In those cases where security regulations may not permit some kinds of data to move out into the wider Internet, we’ve seen a demand for what we call private cloud architecture — something that offers the performance benefits and features of a cloud solution, within an organization, while, at the same time, satisfying regulatory constraints on how companies move or store data.

We also can see how criminals have developed a taste for the vast volumes of sensitive data stored in the cloud, and anticipate that malware creators and other attackers will try to steal data stored in the cloud with increasing frequency.

Security Updates: More than 60 percent of malware attacks come from known vulnerabilities, so no matter whether you’re a one-person shop, or manage many thousands of desktops, maintaining not only the operating system but also the third party applications on which you (and your organization) depend should be a top priority. Besides office applications, attacks in the past year have focused on programs like Adobe Reader, Java, Flash, AutoCAD, media players, graphic design tools, and various browsers and browser plug-ins. IT departments should never let a new computer get to an employee that has anything older than the very latest build of these critical applications.

Consolidation: While not expressly a security trend, larger companies — some in the security space, and some that have not previously played there — have been augmenting their offerings. Intel’s purchase of McAfee, for example, appears to extend their platform beyond mere chipmaking. Other acquisitions, such as Webroot’s purchase of Brightcloud and Prevx, help companies acquire capabilities that can defend against, or remediate, a specific kind of threat. HP, IBM, and Symantec have done similar things, and with each acquisition, the companies gain another part of a toolkit they can use to respond to emerging threats. We expect to see more companies in this space merge and transform themselves over the next year.

A complex and elaborately conceived family of malware that originates in China installs the Apache Web server, as well as half a dozen keylogger and downloader payloads, disguised as components of legitimate apps. We and a few other antivirus vendors are calling this type of malware Taobatuo.

It just so happens that I’ve been setting up a Windows virtual machine with the latest versions of Apache, MySQL, and PHP for an unrelated project. I hadn’t installed these apps onto a Windows box before, and Apache in particular is notoriously finicky about Windows installations, so after several days of trial and error (mostly error) I was somewhat amused to discover, after finally getting Apache to work, that the malware sample I tested actually pulls down its own working, customized Apache installer…along with a bunch of phishing Trojans, keyloggers, and downloaders, all dressed up to look like the services you might see on a Microsoft-based Web server.

It just goes to show how much good these malware creators could accomplish, simply if they wanted to. But that’s clearly not the goal. The malware, along with text files containing instructions for the malware, came from taobao.lylwc.com. That’s not to be confused with Taobao.com, one of China’s most heavily trafficked Internet portals. This site and the real Taobao are not related in any way I can determine, other than the (ab)use of the Taobao name.

The lylwc.com domain itself is quite a piece of work. It claims to offer free downloads or streams of current Hollywood movies, as well as an extensive library of films and TV shows. The operative word is “claims” — when you try to view those movies, the site attempts to push a download of a Trojaned installer for the QVOD media player (a streaming media app that’s popular in China). So let’s just say I wasn’t all that surprised to find the taobao subdomain of this Web site hosting a raft of malware.

We spotted an interesting behavior from a Trojan dropper that belongs to a family of malware named Ponmocup. The file, update.exe (MD5 89f4ea9f0240239e0d97f202d22af325) leaves behind a payload that, among other things, modifies the Hosts file on infected computers to prevent users from visiting popular Bittorrent sites, including The Pirate Bay.

It’s an odd behavior for several reasons. We don’t see many Trojans modify the Hosts file anymore because such modifications are so easily reversed. But more to the point: Why would a criminal care whether anyone else be able to browse The Pirate Bay, a Web site known to host torrents of pirated, copyrighted material? And why also block Mininova, which changed its content model more than a year ago and no longer hosts copyrighted files? None of these things make sense.

It seems at first blush like the act of someone who fancies himself a copyright vigilante, sophisticated enough to build a custom tool such as this, but who isn’t smart enough to know which sites to block.

A Trojan that pulls a sly performance of now-you-see-me-now-you-don’t disguises itself on an infected system as the Adobe Updater, a real program that’s installed alongside such mainstay applications as the Adobe Reader. This method of hiding in plain sight means the downloader, Trojan-Downloader-Karagany, may remain active on an infected system for an extended period of time, reinfecting PCs even after the more obvious payloads have been cleared up.

During the initial infection, subtlety is this Karagany’s strong suit. When executed, it pulls an act I find slightly more interesting than the conventional file copies itself from one place to another, then deletes the original behavior that is so common among contemporary malware.

In this case, the malware app (which uses an Adobe icon) does copy itself to another location — the Application DataAdobe folder under the currently logged-in user’s account, using the filename AdobeUpdater.exe — but leaves behind a benign program afterward, in exactly the same place as the original, and with the same filename as the original. Watch this video to see just how slick this shell game can be.

The Trojan makes a duplicate of a legitimate Windows app (the Microsoft HTML Application Host, or MSHTA.exe), naming the copy with the same filename the Trojan used at the time it was executed, and replaces itself with the renamed MSHTA.exe in precisely the same location. The effect is low-key — the program simply seems to lose its icon.

While nowhere near the size of the mammoth Facebook, the social network Multiply is no slouch. Based in Boca Raton, Florida, the site is designed around not only sharing photos and videos with friends and family, but also a relatively novel concept called social shopping, which permits users of the site to shop together in a virtual marketplace, or even set up an Internet storefront. At last count, according to Multiply’s blog, the site has over 12 million users, which means that the Multiply Market may be one of the largest single shopping Web sites in Southeast Asia, where most of its users live.

I would never have even known about Multiply (it’s one of nearly 200 active social network sites listed on Wikipedia) if it weren’t for one of our Threat Research analysts, Rhoda Aronce, who hails from the Philippines and uses Multiply to keep in touch with family. She received an odd-looking message that appeared to come from Multiply on her Yahoo mail account yesterday, and it set off alarm bells. Good thing, too, because it looks like a spam campaign targeting Multiply users is trying to infect those users’ computers with a rogue AV that calls itself Antivirus Solution 2010 Next.

The initial spam message uses familiar social engineering tropes: It’s a message that looks like it was sent via Multiply’s servers to Rhoda’s Yahoo mail account. The message body reads

heyy! (username), do we know from some place isn’t it? so here’s a special video i did for you, ull recall me!, pls holler me back!!!, kisses <3

The message is dominated with a photo of what looks like a streaming video window that says Click here to see movie. That’s where the fun begins for researchers, but please, don’t click this at home, especially if you’re in the middle of shopping online. Leave getting infected to the professionals. If you see something like this in your email inbox, just delete the message.

In September, I posted an item about a dropper which we call Trojan-Dropper-Headshot. This malware delivers everything including the kitchen sink when it infects your system. It has an absolute ton of payloads, any of which on their own constitute a serious problem. All together, they’re a nightmare.

Among the payloads, we’ve seen this monstrosity drop downloaders (Trojan-Agent-TDSS and Trojan-Downloader-Ncahp, aka Bubnix), adware (Virtumonde, Street-Ads, and Sky-banners), keyloggers (Zbot and LDpinch), clickfraud Trojans (Trojan-Clicker-Vesloruki and at least three other generic clickers), and a Rogue AV called Antivir Solution Pro. So this is one nasty beast that has no qualms about using the shotgun approach to malware infections.

But we also noticed that it has added yet another intriguing installer to its panoply of pests: It’s a small executable named seupd.exe (search engine updater?) that makes two minor (but obnoxious) modifications to Firefox. The result of these modifications changes the behavior of Firefox’s search bar, the small box that lets you send queries directly to search engines, located to the right of the Address Bar.

The modifications are not immediately apparent unless you try to search Google for something, using either the Search Box or the Address Bar: Instead of sending your search to Google, the browser submits search queries to one of six different domains not owned by Google, but which appear to use the Google API to provide results — and, presumably, earn a little ad revenue on the side.

With Christmas fast approaching, (lest we forget the shops have kindly put all the Christmas goods out in September and early October again!) we can expect online attacks to increase as per their normal schedules, ramping up through the end of the year.

With apologies to Sir Winston Churchill, never in the field of Internet conflict was so much harm done to so many by so few.

For all the benefits the Internet provides our lives, no single technology has given so few criminals the ability to cheaply and easily target the many. We’ve seen the rise of the dark economy, where far flung cybercriminals trade skills and produce burglary tools for sale, and we live with the consequences every day. Sophisticated attacks target both our computers and our users, through social engineering.

While the increases in cybercrime incidents seem to indicate a greater number of attackers, the reality is that the growth of the Internet itself gives rise to the ever-increasing volume of botnets, keyloggers and spam. The Internet makes us all contactable and, to a degree, easily identifiable. As we surf the Web, we leave traces of our presence in the form of electronic footprints — cookies, blog postings, and of course, our activities on social networks and other online forums.

And yet, no matter what we do to stem the tide, the problems only seem to increase in size and scope.

You can tune in and listen live to more of Ian Moyse’s predictions for next year’s most serious threats in his free Webinar, ThreatNet 2011, Thursday, November 4, at 10am Eastern.

It’s appropriate that this year’s Blizzcon, the two-day celebration of all things World of Warcraft, takes place during National Cyber Security Awareness Month. No other game is as heavily targeted by thieves as WoW, so we thought this would be as good a time as any to run down some of the malware threats that face gamers. 2010 has been a big year for Trojans that steal game passwords or license keys.

The people who create malware targeting online games show no signs of relenting, nor are they laying down on the job. Innovation is the name of the game, and password-stealers this year innovated their infection techniques to make them more effective and even harder to detect.

Two-factor authentication tokens, such as the Blizzard Authenticator, do a great job of preventing fraud. If you play WoW, the seven or so bucks the Authenticator costs can prevent a lot of headaches if your account becomes compromised by either a Trojan or a phishing Web site. The Authenticator displays a series of numbers that change about once a minute, and a gamer needs to enter these numbers along with a username and password to play the game.

However, while gamers who play Blizzard’s games might find themselves at reduced risk of phishing thanks to the Authenticator, other companies that operate the kinds of massively-multiplayer games most targeted by phishing pages and malware are also targets for theft, and don’t yet offer an equivalent method of securing login credentials.

Last week, Activision/Blizzard released a long-anticipated patch for its immensely popular game, World of Warcraft. While I don’t play this game, a number of our Threat Researchers do, and they’ve been on the lookout for shenanigans. Curtis Fechner found a doozy.

The update comprises a major overhaul of many core systems within the game, affecting the graphics engine, game rules, player abilities, and also the interface. Many players use downloadable, player-created add-ons to further customize the appearance of the user interface; Patches as comprehensive as this one mean that many of the old add-ons simply won’t work until the add-on’s creator releases a new version.

So this week’s rush to patch the game and update some add-ons led to some interesting news. One of the add-ons Curtis uses is something called RatingBuster, written by a player who goes by the name WhiteTooth. The add-on, available from a number of locations, typically comes in the form of a .zip archive and contains several plain text files (called LUA files). But earlier this year, someone registered the domain name ratingbuster.org and began serving Trojans from this legitimate looking Website instead of the RatingBuster add-on.

This fake RatingBuster comes in the form of an executable file named rbv1.4.9.exe — running unknown executables is a big no-no most WoW players know to avoid. This particular executable is a self-extracting RAR archive, which utilities like WinRAR can easily unpack. Inside the archive is another file, a single executable named bot.exe (22794 bytes, MD5: 6831c35e6d19ea0a1e1e9e346368b3e3). This is our malware installer, stored inside the other installer.

The Tacticlol downloader, responsible for a lot of infections over the past year, propagates in two ways: via drive-by downloads, and as a .zip archive attached to messages. Maybe the spam filtering companies finally caught on to the trick, or maybe the Tacticlol distributors are just trying to mix it up, but the latest sample to come over the transom has me scratching my head.

Like most others, this sample came attached to an email made to look like a message that UPS would never send. Once again, the message tries to convince the recipient that the attached file is a shipping label the recipient needs to open and print before he or she can “receive the parcel.” And, as always, the attachment contains an executable installer for the Trojan.

Dear customer

Your parcel has arrived at the post office on October 9. Our
Driver was unable to deliver the parcel to your address.
To receive a parcel you must go to the nearest UPS office and
show your mailing label.
Mailing label is attached to this letter.

You need to print mailing label, and show it in UPS office to
receive the parcel.

Thank you for your attention.
UPS International Services.

But this time, instead of sending a .zip archive with a .zip extension, they sent a message with a .zip archive that has a .jpg extension. And, yeah, that just doesn’t work.

The file isn’t a JPEG image file. If you try to open it in a browser or an image editor, the editor simply errors out and tells you it isn’t an image file, and the story ends right there. I’m sure some Russian malware distributor has been double-facepalming over the waste of a perfectly good scam. Social engineering: You’re doing it wrong.

It’s been more than a week since we started seeing spam email, supposedly sent by the EFTPS (Electronic Federal Tax Payment System, a division of the US Department of the Treasury), informing recipients in dire, bolded text that Your Federal Tax Payment ID: 01037513 has been rejected. I had hoped it would be a faded memory by now, but apparently it just won’t die.

Spam, ladies and gentlemen. It’s a lie, cooked up in a criminal’s troubled mind, with the goal of convincing signficant numbers of people to click a link in the message. It’s a pretty contrived message, which also informs the recipient, in characteristic Spamglish, to “In other way forward information to your accountant adviser.” Apparently, whoever began the campaign needs a refresher in the history of recent Internet scams — this particular scam has been going on again, off again for four years.

Judging by the number of other people asking about this online, the campaign must have been massive. And like a squirrel harassing birds on a feeder, it’s not likely to go away anytime soon.

In this case, the link looks like it’s supposed to go directly to the EFTPS Web site, but the author of the spam simply hyperlinked the URL to point elsewhere. In the case of some of the samples we’ve seen, the messages link to a page on the domain freesite.org; That page contains a single line of HTML to redirect victims to yet another site, which has since been shut down.

So while the spam messages continue to percolate through the email networks, it’s a tiger with no teeth or claws anymore. If you clicked the link, only to end up on a blank page at eftpsid0353546.com — a domain hosted in Russia, on the same server as such esteemed Web sites as qualityhealthmall.com and fdadrugmall.com — rest assured, you’re probably safe, but need to practice the first two parts of Stop. Think. Connect.
