Dok

Dok a.k.a. Retefe is the macOS version of the banking trojan Retefe. It consists of a codesigned Mach-O dropper usually malspammed in an app bundle within a DMG disk image, posing as a document. The primary purpose of the dropper is to install a Tor client as well as a malicious CA certificate and proxy pac URL, in order to redirect traffic to targeted sites through their Tor node, effectively carrying out a MITM attack against selected web traffic. It also installs a custom hosts file to prevent access to Apple and VirusTotal. The macOS version shares its MO, many TTPs and infrastructure with the Windows counterpart.
