In this article “Security researchers from antivirus vendor Trend Micro have come across a Web-based attack that exploits a known vulnerability in Windows Media Player.

Microsoft released a security fix for it on Jan. 10, as part of its monthly patch cycle. “An attacker who successfully exploited this vulnerability could take complete control of an affected system,” the company said at the time.

The so-called drive-by-download attack identified by Trend Micro researchers uses a malicious HTML page to load the malformed MIDI file as an embedded object for the Windows Media Player browser plug-in.

If successful, the exploit downloads and executes a computer Trojan on the targeted system, which Trend Micro detects as TROJ_DLOAD.QYUA. “We’re still conducting further analysis on TROJ_DLOAD.QYUA, but so far we’ve been seeing some serious payload, including rootkit capabilities,” Dela Paz said.”
