Symantec warns of new Word attack

Symantec is warning of a possible 0day flaw in Microsoft Word that is being exploited by cybercriminals.

Criminals have found a new way to attack PC users, taking advantage of what appears to be a new bug in Microsoft's Word software, according to Symantec.

Symantec warned of the attack Tuesday, saying on its Web site> that it had seen attackers exploiting "what is possibly an undisclosed vulnerability affecting Microsoft Word."

The security vendor released few details of the attack, saying that it is still working with Microsoft to confirm its findings. "Initial analysis suggests that some Microsoft Office versions, even when fully patched, are affected by this exploit," Symantec said.

There have been a large number of bugs found in Microsoft's Office software, including Word, over the past few years. In order to exploit these flaws, attackers must typically trick the victim into opening a maliciously encoded Office document, which then allows them to install malicious software on the PC.

In this case, the malicious code is a Trojan horse program, called Backdoor.Darkmoon, which logs the victim's keystrokes in order to steal passwords.

Symantec's antivirus software is now detecting the attack, but the security company recommends that users avoid opening unsolicited Word documents.

This is the second Microsoft attack reported this week. On Monday, Microsoft said that cybercriminals are exploiting a bug in software used by its Access database program. That flaw lies in the Snapshot Viewer ActiveX control, which ships with "all supported versions of Microsoft Office Access except Microsoft Access 2007," Microsoft said in a security advisory.

Reached Tuesday afternoon, Microsoft representatives were unable to comment on the Word flaw.

It’s perfect for mobile workers. Just take it out — it’s small enough to sit anywhere — turn it on, load a sheet of paper, and start printing.
