Zotob.A & Zotob.B Target W2K

Those of you still running Windows 2000 have to be aware of two nasty new Trojans named Zotob.A and Zotob.B - The worm attempts to connect to an IRC channel at a predefined address allowing attackers to, among other things, request system information and download/execute files. Access to numerous security related sites via the hosts file is also disabled.
Patches for this vulnerability have only been available for five days. Keeping abreast of critical security flaws and patching them quickly is your best defence. Never put off a security re-boot until tomorrow - it may be too late.
