ZDNet: Printer Friendly - New worm poses DoS attack threat:
"Security experts warned Friday of a potentially harmful new e-mail worm that is slowly spreading among corporate and home e-mail users.

The Mimail.c worm, a variant of an earlier pest that achieved modest distribution by posing as a message from a company's information technology staff, was first detected late Thursday and managed to infect a handful of PCs. "

According to McAfee's description, Mimail.c spreads by e-mail, appearing in mailboxes as a message with the subject "our private photos." The body of the message promises revealing photos, if the recipient opens up an attached file saved in the Zip compression format. If the file is opened, the worm attempts to spread itself by sending messages to e-mail addresses culled from the infected PC.

The worm also attempts to launch a denial-of-service attack by sending large volumes of "garbage data" to Web addresses associated with DarkProfits, a gaming enthusiast site that has been the subject of a persistent e-mail hoax.

Mimail.c also spoofs the address the message is generated from, with all messages appearing to come from "James" at the same domain as the recipient.
