Court documents unsealed today show how Microsoft s Digital Crimes Unit was able to block some of the cyber attacks conducted by an Iranian-backed advanced persistence threat (APT) group by taking over domains used as part of their core operations. Microsoft sued the hackers in the U.S. District Court for Washington D.C. and managed to take over 99 domains the hackers used in their malicious campaigns. Microsoft tracked the hacking group since 2013, keeping a close watch on its spear-phishing campaigns that targeted businesses, government agencies, activists and journalists.
