New worm steals user information

Monday, 3 November 2003, 12:30 PM EST

A new Internet worm that steals information from users' computers and attempts to shut down two Web sites is spreading.

The worm, dubbed Mimail.C, is a variant of the W32.Mimail worm that surfaced in August. Antivirus software vendors including Symantec, F-Secure and Network Associates rate the worm a "medium" level threat, indicating that it is infecting computers and spreading.

Mimail.C was discovered Friday, the vendors said in bulletins on their Web sites. It arrives as an e-mail with "our private photos" in the subject line and an attached ZIP archive file called "photos.zip." The sender's address is faked to be "james" at the receiver's domain and the body of the message promises revealing photos of a girl at a beach, the antivirus vendors said.

The worm with its attachment was mass-mailed, which most likely started its propagation, according to an alert from Network Associates.
