It turns out Microsoft has something even more formidable than Moscow’s malware: Lawyers. Last year attorneys for the software maker quietly sued the hacker group known as Fancy Bear in a federal court outside Washington DC, accusing it of computer intrusion, cybersquatting, and infringing on Microsoft’s trademarks… Since August, Microsoft has used the lawsuit to wrest control of 70 different command-and-control points from Fancy Bear… Rather than getting physical custody of the servers, which Fancy Bear rents from data centers around the world, Microsoft has been taking over the Internet domain names that route to them. These are addresses like “livemicrosoft[.]net” or “rsshotmail[.]com” that Fancy Bear registers under aliases for about $10 each. Once under Microsoft’s control, the domains get redirected from Russia’s servers to the company’s, cutting off the hackers from their victims, and giving Microsoft a omniscient view of that servers’ network of automated spies.
“In other words,” Microsoft outside counsel Sten Jenson explained in a court filing last year, “any time an infected computer attempts to contact a command-and-control server through one of the domains, it will instead be connected to a Microsoft-controlled, secure server.”
