New 'Dok' malware targets Macs using signed Apple developer certificate: "The code, dubbed "Dok" by security firm Check Point, is said to affect "all versions" of macOS/OS X, and be the first "major scale" malware directed at Mac owners through a "coordinated email phishing campaign." The emails are aimed mostly at Europeans, one example being a German-language message from a supposed Swiss official, claiming problems with the target's tax return."
