Adobe releases emergency update for Flash Player

Posted by   Virus Bulletin on   Apr 14, 2011

Zero-day exploit actively being abused.

Adobe has announced it will release an update for its Flash Player on Friday 15 April, fixing a vulnerability that is currently being exploited.

The vulnerability, which affects Flash Player 10.2.x on Windows, Macintosh, Linux and Solaris, can be used by attackers to take control of an infected system. It is currently being used via Flash embedded in malicious websites and in Microsoft Word documents. In the latter case, spam messages - usually referring to the Fukushima nuclear disaster - arrive with a Word file attached. On opening the file, the Flash code is executed and, after allowing remote access for the attacker, the document is replaced by a clean version to avoid detection.

Though different in details, a similar vulnerability was used in the targeted attack on security company RSA last month, where employees received Excel documents with embedded Flash.

An analysis of the exploit can be found at the Microsoft Malware Protection Center blog here.

How do you know you have been attacked when the malware covers its tracks with a harmless flie? How can you defend your organization against such attacks? TrustDefender's Alex Shipp will present 'Tricks and traps - how malware tries to evade detection' at the VB Seminar on Tuesday 24 May 2011 at the OU campus, Milton Keynes, UK.
