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.
