[ThiefQuest](https://attack.mitre.org/software/S0595) is a virus, data stealer, and wiper that presents itself as ransomware targeting macOS systems. [ThiefQuest](https://attack.mitre.org/software/S0595) was first seen in 2020 distributed via trojanized pirated versions of popular macOS software on Russian forums sharing torrent links.(Citation: Reed thiefquest fake ransom) Even though [ThiefQuest](https://attack.mitre.org/software/S0595) presents itself as ransomware, since the dynamically generated encryption key is never sent to the attacker it may be more appropriately thought of as a form of wiper malware.(Citation: wardle evilquest partii)(Citation: reed thiefquest ransomware analysis)
