Eight variations of the Mytob worm have appeared in the last five days, said Symantec Monday, all of them able to plant a backdoor on infected machines and prevent them from updating security software.

The eight -- dubbed Mytob.j through Mytob.s with some final letter designations skipped -- are mass-mailed worms that spread by sending themselves to addresses they find on the target Windows PC. They can also spread, said Symantec, by exploiting the LSASS vulnerability in Windows. That bug, first disclosed in an April 2004 security bulletin, Microsoft Security Bulletin has been patched by Microsoft. Still, it remains a favorite target of hackers, who continue to find unpatched systems.
