Blaster Variant on the Loose
Security experts are now tracking a new variant of the Blaster worm that was first spotted Wednesday morning.

The new version is nearly identical to the original, except for a new name on the executable file and a different registry key. The variant's file name is "teekids.exe," and the key it adds to the registry is: "Microsoft Inet Xp.." The key is located in the same place as Blaster's key is, according to Neel Mehta, research engineer at Internet Security Systems Inc. in Atlanta.

"Some of our customers say that they're seeing more copies of the new one than the old one, but I think that's just bad luck," Mehta says. "It scans exactly the same way and acts exactly the same as Blaster."

Mehta said that some copies of the new variant are coming packed with various known Windows Trojan programs, as well.
