July 6, 2009

A vulnerability in Microsoft Video ActiveX control could allow a hacker to remotely control a user’s PC without any user interaction. Microsoft Security Advisory (972890) states that an attacker could exploit this vulnerability by convincing a user to access a specially crafted website or HTML email message. This vulnerability is not a risk if you are using Windows Vista.

Approximately 967 Chinese websites are reported to be infected by a malicious script that leads users to successive redirections finally downloading a JPG file containing the exploit, detected by Trend Micro as JS_DLOADER.BD.
