Blaster - RPC DCOM worm hits the net
A malicious worm that exploits last month's RPC DCOM vulnerability struck the Internet Monday afternoon, targeting unpatched Windows 2000 and Windows XP machines.
The worm, dubbed "Blaster" and "LovSan" by security and anti-virus companies, attacks vulnerable machines over TCP port 135, then spawns a shell and initiates a TFTP file transfer to retrieve the worm's code.
The worm apparently has no malicious payload, but is reportedly crashing some PCs as it attempts to infect them. Additionally, according to an analysis from Symantec's DeepSight Threat Management System, the malware is programmed to launch a denial of service attack against Microsoft's windowsupdate.com site on August 16th.
