Researchers concluded that Chinese Ministry of State Security is behind APT3

APT3 is the first threat actor group that has been attributed with a high degree of confidence directly to the Chinese Ministry of State Security (MSS).
On May 9, a mysterious group called “intrusiontruth” attributed APT3 to a company, Guangzhou Boyu Information Technology Company, based in Guangzhou, China.
Recorded Future’s open source research and analysis has corroborated the company, also known as Boyusec, is working on behalf of the Chinese Ministry of State Security.
Customers should re-examine any intrusion activity known or suspected to be APT3 and all activity from associated malware families as well as re-evaluate security controls and policies.
