New Botnet Dwarfs Storm

Posted by CmdrTaco on from the that's-a-lotta-zombies dept.

ancientribe writes "Storm is no longer the world's largest botnet: Researchers at Damballa have discovered Kraken, a botnet of 400,000 zombies — twice the size of Storm. But even more disturbing is that it has infected machines at 50 of the Fortune 500, and is undetectable in over 80 percent of machines running antivirus software. Kraken appears to be evading detection by a combination of clever obfuscation techniques that hinder its detection and analysis by researchers."

    Why are email providers still allowing people to send executables out via email? I believe only gmail blocks them. End users shouldnt be receiving executables via email. If you need to send them something they can get it via http or ftp. This will stop the whole "but it looked like an acrobat file" social hack we've been seeing.

    This includes executables in container formats too (zip, rar, etc).
