Petya, Dead but Still Dancing

There are a few interesting things to say about the current ransomware Petya. One thing is clear, there is no “kill-switch”. After some preliminary tracking of the domains which presumably deliver the payload for its RTF (Windows document exploit) delivery system and cross referencing it to passive intelligence about the domain name, we noticed the frequency of 2 million hits within an hour. The domains we tracked are not currently serving the payload and are down.
