The latest Adobe Flash bug affects the latest version of the Flash application. The attack scenario is extremely well crafted in order not to draw even the slightest sign of suspicion on the users side. The first step of the attack makes use of a specially-crafted PDF file bundled as an attachment to a spam message impersonating a press release. Along with the malicious file, the PDF also drops a regular PDF document and a batch script that will kick in later to clean things up. If you are unsure about the security of your system then download a 40-day evaluation version of BitDefender Total Security 2011.”]
