North Korean hackers use AI deepfake videos to target cryptocurrency practitioners.
On January 27, Decrypt reported that North Korean-linked hacker groups are using AI-generated deepfake video calls to target individuals in the cryptocurrency industry.
According to Martin Kuchař, co-founder of $BTC Prague, attackers contact targets through compromised Telegram accounts, arrange video calls, and use $AI technology to impersonate people known to the victims. During the call, the attackers claim there are audio problems, inducing the victims to install a so-called "Zoom audio repair tool," which is actually malware. Once installed, the hackers can completely control the system, steal Bitcoin and take over accounts.
Security researchers attribute this attack method to North Korea's BlueNoroff group (a branch of the Lazarus Group). In 2025, such AI-driven scams have caused cryptocurrency-related losses to reach a record $17.00B.
