According to CoinMeta, North Korean hacker groups used fake recruitment information to distribute malware, resulting in nearly 30,000 devices being infected and the theft of cryptocurrencies worth over $107 million as well as corporate data. These groups disguised themselves as technology companies or startups to recruit personnel, enticing job seekers to click on malicious documents on social media platforms. They then obtained illegal profits by implanting backdoors, distributing ransomware, stealing private keys, or making direct transfers.
