Summary

Hide ▲

PhantomRaven is an active npm supply-chain campaign that began in August 2025 and has grown to 126 npm libraries with more than 86,000 installs. The packages hide malicious code behind a custom HTTP URL to packages.storeartifact[.]com, which lets npm fetch Remote Dynamic Dependencies (RDD) outside npmjs[.]com and bypass static scanners. The payload uses a pre-install hook to scan developer systems and exfiltrate authentication tokens, CI/CD secrets, and GitHub credentials. The campaign continues to target developers and their build environments through package names designed to look legitimate.

    PhantomRaven npm packages use remote dependencies to steal developer credentials

    Technical Analysis Update

    Koi Security uncovered PhantomRaven, an active npm supply-chain campaign that hides malicious code behind a custom HTTP URL to packages.storeartifact[.]com, causing npm to fetch remote dynamic dependencies outside npmjs[.]com and bypass static scanners. The packages use pre-install hooks to execute a main payload that scans developer environments for email addresses, gathers CI/CD environment details, collects system fingerprints including the public IP address, and exfiltrates authentication tokens, CI/CD secrets, and GitHub credentials. The operation had grown to 126 npm libraries with more than 86,000 installs, and the package naming strategy was linked to slopsquatting.
