Subject: SV: JPEG GDI+ (MS04-028) Exploit @


>Hex verified its hxxp:// with payload @

>trojan (

Indeed. The malware, refered to in the jpg-exploit, was hosted as
"msmsgs.exe" (Netsnake-H) and has now been removed, so infection from that
specific URL, is no longer a threat.

Just thought you might like to know.

However, I did manage to grab a copy of the code. This is actually more a
network worm than a traditional backdoor. When executed Netsnake will drop a
copy of itself as psinthk.dll and iexeplore.exe to the local harddisk
(%windows systemfolder%). Netsnake will spread on IRC networks and also
search for workstations and servers protected by weak passwords. This is not
mentioned in the write-up by Sophos.
