Malicious MIDI files lead to rootkit malware

A Windows Media remote code execution flaw that has been patched in the last Patch Tuesday is being exploited by attackers in the wild to deliver malware to the targets' computer, warns Trend Micro.

The victims are lured to a malicious web page (http://images.{BLOCKED}p.com/mp.html), which hosts a specially crafted MIDI file and JavaScript.

The page's HTML file calls upon the MIDI file to trigger the exploit, and the JavaScript decodes shellcode that is already embedded in the HTML file. Upon execution, the shellcode downloads an encrypted binary from another site.
