Posted: August 27, 2012

Threat Metric

Threat Level: 9/10
Infected PCs: 16
First Seen: August 27, 2012
OS(es) Affected: Windows

Trojan:Win32/WipMBR.A is a Trojan dropper that installs Trojan:Win32/WipMBR.B, a PC threat that causes permanent damage to Windows and prevents your PC from loading. Given the unusually destructive nature of Trojan:Win32/WipMBR.A's payload, a Trojan:Win32/WipMBR.A infection may be hard to miss, but will require you to repair your operating system before you can even begin to delete Trojan:Win32/WipMBR.A or Trojan:Win32/WipMBR.B. Therefore, SpywareRemove.com malware researchers recommend that you do your utmost to prevent a Trojan:Win32/WipMBR.A infection in the first place with appropriate online safety habits and anti-malware security programs.

Trojan:Win32/WipMBR.A: Going 'Old School' on Your Master Boot Record

Even though malware has evolved to become extraordinarily sophisticated, recent schools of thought for malware development tend to emphasize the potential for profit through subtle attacks, such as banking Trojan attacks that insert malicious content into the web pages of bank websites. Trojan:Win32/WipMBR.A stands in sharp contrast as a throwback to an elderly style of malware, wherein the foremost goal was to annoy the PC user or actually destroy the PC itself.

Taken individually, Trojan:Win32/WipMBR.A's primary responsibility is the installation of a related Trojan, Trojan:Win32/WipMBR.B. SpywareRemove.com malware researchers have yet to find the propagation routes for Trojan:Win32/WipMBR.A, although they do note that Trojan:Win32/WipMBR.A is a recently-identified PC threat that's still in distribution as of this month of 2012. Trojan:Win32/WipMBR.A is compatible with 32-bit and 64-bit versions of Windows, and includes slightly different payloads for each version of that OS, although the consequences are, in the end, identical.

What Happens When Trojan:Win32/WipMBR.A's Payload Reaches the End of Its Fuse

After Trojan:Win32/WipMBR.A has installed Trojan:Win32/WipMBR.B, it sets a job scheduled to launch Trojan:Win32/WipMBR.B immediately. Trojan:Win32/WipMBR.B proceeds to overwrite the MBR and other Windows components with fragmented JPEG data. This causes system failure and will result in Windows (which is immediately rebooted by Trojan:Win32/WipMBR.B) being unable to load.

If it's inconvenient for you to repair your OS with its source materials right away, you can also attempt to boot your PC from a USB drive-based OS. The original operating system will need to have its damaged files restored from a clean source before Trojan:Win32/WipMBR.A or related PC threats can be deleted safely. On the bright side, most other files and programs on your PC (such as text documents, pictures and audio files) should be undamaged after you repair the OS issues caused by Trojan:Win32/WipMBR.A's payload.

SpywareRemove.com malware experts also stress that Trojan:Win32/WipMBR.A has displayed a limited ability to distribute itself through local networks (worm-style propagation) by copying itself to vulnerable locations and then installing itself automatically. You should prevent other PCs from accessing network-shared folders or drives on your PC if you suspect any possibility of a Trojan:Win32/WipMBR.A infection.

Aliases of Trojan:Win32/WipMBR.A include TR/Crypt.FKM.Gen, W32/Dropper.gen8!Maximus and W32/Troj_Generic.DKYIW.
