Urgent Alert: 'Blackworm' D-Day is Friday, February 3, 2006

Note: This issue has been resolved and is posted here for archival purposes only.

Security experts have raised an advisory for a potentially destructive email worm due to hit Friday, February 3, 2006.

The worm can completely destroy important documents on an infected machine. It tricks email users into executing an attachment. Blackworm, which is programmed to strike on the third day of every month, goes by a variety of names. In addition to Kama Sutra, according to eWeek, the worm has been named Blackmal, MyWife and Nyxem.

Blackworm disables most antivirus products and attempts to delete them. The worm emails itself using a variety of extensions and file names, including .DOC (Microsoft Word), .XLS (Excel), and .ZIP (zipped) files. It also adds itself to the list of auto-start programs in the Windows Registry.

Blackworm can be detected by virus prevention programs with up-to-date antivirus signatures (January 23rd or later). But if the PC was infected before those virus definition signatures were obtained, then the antivirus software may not detect or clean up the infection.

Estimates put the number of infected computers at 700,000 (300,000 in the past week). Most of the systems affected appear to be home computers.

We urge you to:

  1. Update your virus protection program's definition files,
  2. Scan your computer for viruses and worms,
  3. Back up all your data files and remove any backup drive from the computer, and
  4. Do not turn on your PC this Friday unless you're sure you are properly protected.

Be careful about automated backups, too. If you're backing up daily, you might end up backing up corrupted files instead of the good ones.

As always, we're here to help.
