  • State-sponsored attackers crafted convincing fake video calls to target cryptocurrency firms
  • A clipboard hijack trick replaced benign commands with malware‑deploying code
  • The operation enabled rapid credential theft, persistence, and full system compromise

Security researchers Arctic Wolf have revealed details of a highly sophisticated campaign targeting North American Web3 and cryptocurrency companies.

It is conducted by state-sponsored threat actors called BlueNoroff, a financially motivated subgroup of the dreaded North Korean Lazarus Group, with a goal of establishing persistent access on their target’s devices.

They do so by tricking the victim into installing malware on the computers themselves, but the way they do it is quite advanced.

While preparing for the attack, the threat actors would use real, high-value people from the Web3 world, generate convincing headshots using ChatGPT, and create semi-animated videos using Adobe Premiere Pro 2021.

They would then create a fake Zoom video call website identical to the actual Zoom call page, and would display the video to make it look even more convincing.

BlueNoroff would then invite the actual victim through Calendly, almost half a year into the future (most likely to make it look more convincing - important people are, after all, super busy).

When the victim clicks on the Zoom link, they see what they’re used to seeing - a video call page with the person on the other side moving and acting as if they were real. However, eight seconds into the call, a message would pop up across the screen, saying their “SDK is deprecated” and presenting them with an “Update Now” button.
