Microsoft's PowerPoint application is being used in a new attack that
exploits an unpatched vulnerability in the popular Office app. The
software giant yesterday issued a security alert confirming "limited and
targeted attacks" were under way using malicious PowerPoint files that
exploit the flaw.
The exploits carry a Trojan, according to Microsoft, and in an
interesting twist, the exploit files were recently submitted to the
VirusTotal free malware-scanning site. "Either the miscreants who
created these exploits were looking to see how antivirus products detect
their new files, or the victims were looking to get some information
about their maliciousness," blogged Cristian Craioveanu and Ziv Mador of
Microsoft's Malware Protection Center.
When exploited, the vulnerability can give an attacker local rights to a
user's machine if he opens the malicious PowerPoint file, which is
currently being delivered via targeted email messages, but can also be
pushed via a Website or instant messaging link.
The vulnerability affects PowerPoint 2000 Service Pack 3, PowerPoint
2002 Service Pack 3, PowerPoint 2003 Service Pack 3, and Microsoft
Office 2004 for Mac . The newer Microsoft Office PowerPoint 2007 and
Microsoft Office for Mac 2008 are immune.
