Illustration: FBI says North Korean hackers used fake video calls in $400m crypto theft
US authorities say North Korean state-sponsored hackers have taken more than $400 million in cryptocurrency using fake video calls hosted over imposter versions of Zoom, Microsoft Teams and Google Meet; the FBI says more than 900 victims have fallen prey to the scheme in the last 18 months.

The bureau, which calls the campaign FaceStealer, says it has been active for the last 18 months. The scheme "aggressively targets" workers in the cryptocurrency and web3 sectors, particularly those developing and maintaining open-source software. Hackers use fake or hijacked social media accounts to invite victims onto fake video conferencing platforms, where they play pre-recorded footage of an acquaintance to simulate a legitimate call. When the audio appears to malfunction, the target is prompted to click a fix link that instead installs malware, giving the hackers access to their contacts and apps. The calls are secretly recorded and reused to scam further targets.

The announcement comes a week after Binance, the world's largest crypto exchange, revealed a record $6.3 billion hack that US authorities attributed to North Korea-linked actors, a claim Pyongyang has denied.

"The North Korean regime relies on proceeds from large-scale cryptocurrency theft to fund its illicit weapons program, stealing billions of dollars in recent years," FBI cyber director Brett Leatherman said. "If you can't imagine a scenario where you might fall prey to it, you are not thinking creatively enough," added Patrick Grandy, assistant director in charge of the bureau's Los Angeles field office. "It exploits our trust in ubiquitous video conference platforms and valued personal relationships."

The FBI described FaceStealer as a highly effective social engineering scheme capable of deceiving even the most experienced technical and security-conscious computer user.

Analysis

Why This Matters

  • The $400 million theft from over 900 victims highlights a highly sophisticated and scalable social engineering operation by a state actor, demonstrating how trust in routine digital tools can be weaponised.
  • Proceeds from these heists are used to fund North Korea's illicit weapons programs, directly linking cybersecurity to geopolitical and non-proliferation concerns.
  • The focus on cryptocurrency and web3 professionals points to a persistent, evolving threat against a specific, high-value sector of the digital economy.

Background

North Korea has long been accused by security researchers and governments of using cyber operations, including cryptocurrency theft and ransomware, to generate revenue in the face of international sanctions. The US government has previously attributed large-scale crypto heists to North Korean state-sponsored groups.

Key Perspectives

FBI: describes FaceStealer as a highly effective social engineering campaign that generated over $400 million for North Korea's weapons programs by exploiting trust in video platforms and personal relationships to target crypto professionals. North Korean Government: has denied US claims linking it to the recent record $6.3 billion Binance hack, which authorities say was carried out by similar North Korean-linked actors.

What to Watch

  • Whether international cybersecurity agencies issue coordinated alerts or sanctions targeting the Facestealer infrastructure.
  • The potential for the technique to be adapted and deployed against other professional sectors.
  • Continued US intelligence assessments linking major crypto thefts to North Korean weapons funding.
