PhantomRaven Supply-Chain Attack Infects npm Ecosystem

Koi Security has discovered a massive supply-chain attack called PhantomRaven, which has infected the npm ecosystem with 126 malicious packages downloaded over 86,000 times. The campaign, active since August 2025, steals npm authentication tokens, GitHub credentials, and CI/CD secrets by concealing malicious code in dependencies. The attackers used Remote Dynamic Dependencies (RDD) to bypass security scanners, making the packages appear harmless. The malware executed automatically during installation, performing aggressive reconnaissance and exfiltration. Koi Security noted the use of AI-driven slopsquatting to create plausible-sounding package names, tricking developers into trusting malicious packages.
