The malware hides in the legitimate game downloads, signed with a real certificate; connections to ShadowHammer have been found. Victims include fans of the popular first-person shooter game, Point Blank. Another victim is a zombie survival game called Infestation: Survivor Stories (a.k.a The War Z) Kaspersky Lab and ESET have spotted downloads of the affected games that have had backdoors inserted into them. They’re also signed with legitimate digital certificates that adversaries have managed to abuse, which allows the files to skate past antivirus.
