Unlike years ago, modern malware rarely possesses true viral capabilities. But alas, 2020 is full of (unfortunate) surprises! This talk will provide a comprehensive analysis of a recent macOS threat named EvilQuest. Though initially thought to be a rather mundane piece of ransomware, further analysis revealed something far more powerful and insidious. So listen in, as we detail its infection vector, persistence mechanism, and anti-analysis logic, as well as its (surprising) viral capabilities, file exfiltration logic, remote tasking capabilities, and ransomware logic. We'll wrap up the talk by discussing IOCs and (generic) behaviour-based detection approaches.
