From: dufresne at winternet.com (Ron DuFresne) Subject: MyDoom download info February 12, The Register (UK) - Nachi variant wipes MyDoom from PCs. A new variant of the Nachi worm which attempts to cleanse computers infected by MyDoom and download Microsoft security patches to unprotected computers arrived on the Internet Thursday, February 12. Nachi.B (also called Welchi) uses the same security vulnerability exploited by the Blaster worm to spread. Once it infects target machines the worm attempts to search and destroy any traces of MyDoom infection -- before downloading patches for the Microsoft vulnerability it used to infect the system in the first place. The scanning traffic generated by the original Nachi worm in August 2003 caused huge problems. Anti-virus vendors fear a repeat performance this time around. This concern is compounded by the plethora of new viruses released in recent days. As well as the Doomjuice worms (which target Microsoft's Website in DDoS attacks), we have MyDoom and variants and now a Nachi variant. Thursday also saw the arrival of a Trojan, called Mitglieder.H, with the ability to spread to computers infected with the MyDoom.A worm.
