There's some ingenious virus-laden e-mail spam making the rounds right now.

The latest warns that if you use various illicit BitTorrent freebie sites -- you're usage is being tracked. BitTorrent porn super users might be more likely than others to be sucked into opening a virus-filled attachment in the e-mail that purports to detail the violations.

The e-mail looks like it comes from Los Angeles-based MediaDefender – Hollywood's hired guns that ferret out online privacy. The e-mail isn't from MediaDefender and is sent out at random, victimizing the unsuspecting.

It has been getting a lot of people's attention because millions of people use BitTorrent trackers that point the way to free music, movies, software, games and more.

The e-mail warns:

"We have attached a report about the copyrighted movies, music, software you
downloaded or searched on these web pages. We strongly advise you to stop any
future activities regarding the downloading of illegal content or you can
expect prosecution by 17 U.S.C. §§ 512, 1201?1205, 1301?1332; 28 U.S.C. §
4001 laws."

Regarding that virus, Threat Level's friend, the always clued in Ernesto at TorrentFreak, informs that it's the pesky mytob worm (W32.Mytob@mm) that installs a trojan, and allows outsiders to gain access to your computer.
