GreyEnergy is an Advanced Persistent Threat (APT) which has been targeting industrial networks in Eastern European countries for several years.
As a security analyst, I have studied the malware and provide a detailed description of how it works, from the moment that someone receives a phishing email, until the malware is installed in a PC. We also provide the GreyEnergy Unpacker, a free tool for other analysts to use for further analysis of this advanced persistent threat.
Recently a new advanced threat targeting the energy sector was disclosed. Called GreyEnergy, this malware is the successor to BlackEnergy, which brought down part of the Ukraine power grid in 2015.
