North Korea’s BlueNoroff uses deepfakes in Zoom calls to hack crypto workers

2025-06-20  Per Henrikson

The North Korea-linked threat group BlueNoroff has been caught deploying deepfake Zoom meetings to target an employee at a cryptocurrency foundation, aiming to install malware on macOS systems. According to cybersecurity firm Huntress, the attack began through a Telegram message that redirected the victim to a fake Zoom site. Over several weeks, the employee was lured into a group video call featuring AI-generated replicas of company executives. When the employee encountered microphone issues during the meeting, the fake participants instructed them to download a Zoom extension, which instead executed a malicious AppleScript. The script covertly fetched multiple payloads, installed Rosetta 2, and prompted for the system password while wiping command histories to hide forensic traces. Eight malicious binaries were uncovered on the compromised machine, including keyloggers, information stealers, and remote access tools.
