Alternate Title: “That’s One Big Lawsuit”
Since this Sony Rootkit Phones Home, security expert Dan Kaminsky decided to use a technique called Reverse DNS cache snooping to find out approximately how many systems were phoning home. The results weren’t pretty. Over one half million (568,200 to be exact) nameservers said that they’d been used to phone home.
This means that at least one computer behind each of these nameservers is infected. But since we all know that nameservers usually field requests from many computers, this number could be much higher.
Perhaps the mythical Warhol Worm, isn’t actually a worm at all.
