North Korean Hackers Target Developers with Massive npm Supply-Chain Attack
In November 2025, North Korean threat actors associated with the "Contagious Interview" campaign launched an extensive supply-chain attack by publishing 197 malicious npm packages. According to threat intelligence from Socket, these packages—downloaded over 31,000 times—were engineered to distribute a new OtterCookie malware variant, combining features from BeaverTail and earlier OtterCookie strains. The attackers leveraged the npm ecosystem to infiltrate development pipelines, enabling remote code execution and persistent access across compromised environments, potentially exposing confidential data and intellectual property. This incident underscores the escalating risks of supply chain attacks targeting software registries. With developers increasingly relying on open-source dependencies, threat actors are focusing on abusing trusted platforms like npm to propagate sophisticated malware at scale. Organizations must strengthen software supply chain security and closely monitor package repositories to mitigate these emerging threats.
