How North Korea's Contagious Interview Campaign Stole $10.7M Through Fake Job Offers
North Korean threat actors operating the Contagious Interview campaign have compromised over 30,000 devices across 100+ countries since 2022, stealing $10.71 million in cryptocurrency from 7,000+ wallets. The WaterPlum group targets web developers, engineers, and blockchain specialists through fake job offers on LinkedIn, delivering malware families including BeaverTail, InvisibleFerret, and FlexibleFerret via malicious coding assessments. The campaign enables persistent access for data exfiltration, corporate espionage, and facilitates North Korean IT worker infiltration schemes. This incident highlights the evolving sophistication of state-sponsored social engineering attacks targeting the growing cryptocurrency and Web3 workforce. The campaign's integration with North Korean IT worker programs demonstrates how threat actors are weaponizing legitimate remote work trends to bypass sanctions and establish persistent corporate access for long-term espionage operations.
