WARNING: Fake Twitter Invites Carry Malicious Worm

6/20/09 • Mashable

The emails carry the subject line “Your friend invited you to twitter!”, while the sender’s address is spoofed as “invitations@twitter.com”. Unlike a typical Twitter invite, however, the email contains no invitation link: instead it carries the attached file Invitation Card.zip, tempting the receiver to download it. The attachment, of course, contains W32.Ackantta.B@mm – a nasty, email address-harvesting worm.
