Iran cyberspy group hit in coordinated European raids

European authorities have taken action to take down a cyber-espionage campaign believed to be linked to Iran's powerful Revolutionary Guard, the first operation of its kind since Tehran signed a nuclear treaty, according to security researchers.

The hacker group - dubbed "Rocket Kitten" by security experts who have been hunting the hacker group since early 2014 - has mounted cyber-attacks on high-profile political and military figures globally since that time, according to researchers from several cyber security firms who have monitored its activities.
