Hackers have painted a bull's-eye on an Adobe Reader flaw patched by the company earlier this week.
The attackers are targeting a vulnerability in Adobe Reader 8.1.2 uncovered by Core Security Technologies. According to an advisory from the SANS Institute's Internet Storm Center, attackers are using malicious PDF files toexploit the bug, which Adobe Systems patched Nov. 4. If successfully exploited, the bug could allow hackers to take complete control of a compromised system.
In addition to Reader, the bug affects Adobe Acrobat 8.1.2. Officials at Adobe advise users to either update their software to Version 9 of Reader and Acrobat, which are not susceptible to the attack, or deploy the patch.
