DNSChanger – Cleaning Up 4 Million Infected Hosts
The internet is full of infected hosts. Let’s just make a conservative guesstimate that there are more than 40 million infected victim hosts and malware serving “hosts” connected to the internet at any one time, including both traditional computing devices, network devices and smartphones. That’s a lot of resources churning out cybercrime, viruses, worms, exploits, spyware. There have been many suggestions about how to go about cleaning up the mess, the challenges are complex, and current cleanups taking longer than expected.
Mass exploitation continues to be an ongoing effort for cybercriminals and a major problem – it’s partly a numbers game for them. Although exploiting and infecting millions of machines may attract LE attention at some point, it’s a risk some are willing to take in pursuit of millions of dollars that could probably be better made elsewhere with the same effort. So take, for example, the current DNSChanger cleanup. Here is a traditional profit motivated 4 million PC and Mac node malware case worked by the Fbi, finishing with a successful set of arrests and server takedown.
