As if we didn’t have enough to deal with this week — after a Microsoft patch Tuesday that brought with it a boatload of security updates for Windows, Office, Silverlight, Visual Studio, and other programs — some enterprising malware distributor is emailing around bogus tracking number malware dressed up in the icon of a PDF document, and that malware is downloading payloads named after the updaters that Windows Update retrieves during an update.

The malware arrived into one of our spam collection points with an attachment named UPS_document.zip. Way to be original there, criminals. Inside the Zip file was an executable downloader named UPS_Document.exe. Upon execution, it retrieves at least three payloads, including a copy of SpyEye (a password stealing Trojan), a tiny agent sending profiling information about the infected system, and a fraudulent “rogue system utility” called (on my XP testbed) Windows XP Restore.

The rogue takes on much of the appearance of a previous Rogue of the Week, named Windows Recovery. In fact, Windows XP Restore looks to be a very slightly modified duplicate of that software. If you’ve been hit with either rogue, there are some cool free tools for you to download that will repair some of the damage; Read on for details.

Rogue of the Week: Windows Recovery

Word from the AMR group last week was that there weren’t many changes from the previous week; Many of the same rogue antivirus previously reported in this blog continue to plague the Internet.

This week I decided to focus on a rogue that’s recently become a problem. It goes by the name Windows Recovery, though it’s also been called Ultra Defragger or HDD Rescue by other AV vendors. Bottom line, it’s still a fraudulent program which relies on deception and trickery to convince a victim to fork over some cash for a “fix.” It’s just not a rogue antivirus; Call it a rogue system utility. Fortunately, the damage caused by this rogue is actually relatively straighforward to manually clean up.

The gist of this rogue’s deception comes down to trying to convince the victim that their computer hard drive has experienced some sort of major malfunction. To accomplish this, the rogue does a lot of sneaky stuff: For instance, it flags all files on the boot drive with the “hidden” attribute, then uses registry tricks to prevent Windows from displaying any hidden icons.

It also moves any shortcuts that point to programs (both from the start menu and on the desktop) into the Temp folder, effectively neutering the utility of the Start menu. (We have a free tool that can fix this.) And it uses the Registry to disable the user’s ability to open the Task Manager, changes the system wallpaper (and prevents you from changing that wallpaper), and hides the entire desktop from view. (And we have another free tool that can fix this, too.)

It’s been said that sunlight sanitizes almost everything it shines on. Beginning this week, and every week from now on, we’ll focus a concentrated beam on the rogue antivirus programs our support staff and Threat Research team have been working to remediate.

Rogues have a tendency to switch up their names, user interface, and other outward characteristics, while retaining most of the same internal functionality — and by functionality I mean the fraudulent tricks these forms of malware use to make it difficult for someone to identify them as malicious or remove them from an infected computer. It’s not as though the charlatans behind these scams (or their parents) ever made anything that was actually useful or desirable.

So for our inaugural Rogue of the Week post, we bring you notes on MS Removal Tool and XP Total Security, courtesy of Threat Research Analysts Brenden Vaughan and Stephen Ham.
