One it finds a vulnerable system, it will spawn a shell and use it to download the actual worm via tftp. The name of the binary is msblast.exe. It is packed with UPX and will self extract. The size of the binary is about 11kByte unpacked, and 6kBytes packed:Has anyone seen/heard of this virus propagating through email in any way? We appear to have been infected on a network that is very heavily firewalled from the outside, and are trying to track down possibly entry methods the worm might have had...A large number of networks have unknown and unauthorized back doors. If it's a decent-sized network and you haven't audited it, don't assume that the firewalling is effective.
