Chinese hackers cloned a Windows security flaw stolen from the NSA

The investigation into a malware tool being used by Chinese hackers has revealed it to be a copy of software reportedly originally developed by part of the US National Security Agency (NSA).

Security researchers at Check Point Research (CPR) originally thought the tool dubbed Jian was custom built by Chinese threat actors. However further CPR digging revealed that it is a clone of the EpMe software, which was used by the Equation Group, which has long been suspected to operate on the behest of the NSA.
