Subject: New Worm Discovery - Potential Korgo Variant

Hello,

we also came across a system with a variant of Korgo/Padobot that was NOT
infected with sasser before!
Infection possibly took place via HTTP, a file containing the virus was
found in the temporary internet files.
Looks like this new padobot is also able to spread via Internet Expolrer
vulnerabilities .

Regards, Oliver Heinz
