New malware overwrites software updaters

For the first time security researchers have spotted a type of malicious software that overwrites update functions for other applications, which could pose additional long-term risks for users.

The malware, which infects Windows computers, masks itself as an updater for Adobe Systems' products and other software such as Java, wrote Nguyen Cong Cuong, an analyst with Bach Khoa Internetwork Security (BKIS), a Vietnamese security company, on its blog.

BKIS showed screen shots of a variant of the malware that imitates Adobe Reader version 9 and overwrites the AdobeUpdater.exe, which regularly checks in with Adobe to see if a new version of the software is available.

Users can inadvertently install malware on computers if they open malicious e-mail attachments or visit Web sites that target specific software vulnerabilities. Adobe's products are one of the most targeted by hackers due to their wide installation base.
