If you use Windows XP, regardless of patches and service packs, read this right now:
Summary Security Focus has published information of an unpatched flaw in the way Windows handles Windows MetaFile (WMF) images.
WMF images can be used in web development, which increases this threat. The images are supported by both Internet Explorer and Mozilla Firefox.
Possible Methods of Exploitation
- Web Browsing
- Peer-to-Peer (P2P)
- Instant Messaging
Signs of Exploitation
- Desktop wallpaper changed to a rather large warning message
- Small red "X" icon in the system tray area (by the clock on the taskbar)
- Presence of increased network activity, unusual processes, etc.
Additional Notes While it appears as though all reports indicated that the infected machines had the Google Desktop Search installed, this vulnerability exists in Windows, not Google Desktop Search.
