The Ethereum Foundation has revealed that its ETH Rangers initiative funded a six-month project, the Ketman Project, which identified 100 North Korean operatives infiltrating Web3 companies under false identities. Launched in late 2024, the project aims to bolster security within the Ethereum ecosystem, which has been threatened by North Korean hacking activities, notably from groups like the Lazarus Group. The Ketman Project reached out to 53 projects to inform them about the presence of these operatives. It developed an open-source detection tool to identify suspicious activities on GitHub and co-authored a framework with the Security Alliance, a blockchain-focused nonprofit, to help pinpoint DPRK IT workers. The project highlighted various tactics used by these operatives, including reusing avatars and exposing unlinked email addresses during screen sharing. This initiative addresses a significant operational security threat in the crypto sector, where North Korean hackers have been responsible for billions in stolen assets.
