North Korean hackers have reportedly used deepfake technology to impersonate executives during a fake Zoom call in an attempt to install malware and steal cryptocurrency from a targeted employee.
Cybersecurity firm Huntress identified the scheme, which involved a convincingly staged meeting and a custom-built AppleScript targeting macOS systems—an unusual move that signals the rising sophistication of state-sponsored cyberattacks.
The incident began with a fraudulent Calendly invitation, which redirected the employee to a fake Zoom link controlled by the attackers. Weeks later, the employee joined what appeared to be a routine video call with company leadership. In reality, the participants were AI-generated deepfakes.
When audio issues arose, the hackers convinced the user to install what was supposedly a Zoom extension but was, in fact, malware designed to hijack cryptocurrency wallets and steal clipboard data.
Huntress traced the attack to TA444, a North Korean group also known by names like BlueNoroff and STARDUST CHOLLIMA. Their malware was built to extract sensitive financial data while disguising its presence and erasing traces once the job was done.
Security experts warn that remote workers and companies have to be especially cautious. Unfamiliar calendar links, sudden platform changes, or requests to install new software should be treated as warning signs.
Verifying suspicious meeting invites through alternative contact methods — like a direct phone call — is a vital but straightforward way to prevent damage.
