Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-5689/ (Markdown: https://insights.sbomify.com/MAL-2026-5689/index.md)","id":"MAL-2026-5689","markdown":"https://insights.sbomify.com/MAL-2026-5689/index.md","name":"MAL-2026-5689","record":{"aliases":["GHSA-9h8h-37p7-873r"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On install, postinstall.js evaluates a targeting heuristic (isRealTarget) that fires only when the build environment looks like a real corporate CI/Docker host — cwd not under /tmp, hostname not matching researcher patterns ('hetzner','nijin','ec2.internal'), and either the npm registry points at a private mirror (nexus.local/verdaccio) or the hostname is a 12-hex container ID with /app/ cwd. When the heuristic matches, the script writes /usr/local/bin/.spectral-shell (mode 0755) containing a /bin/sh reverse shell to snnkj-159-153-180-200.run.pinggy-free.link:38493 via /dev/tcp, then installs a root cron entry at /etc/cron.d/spectral-shell ('* * * * * root /usr/local/bin/.spectral-shell') with a fallback to the user crontab, starts cron, and immediately spawns the shell detached. It also PUTs JSON containing uid, hostname, and cwd to http://154.57.164.71:31289/api/modules/ECT-472839 to confirm compromise to the operator. The combination — interactive reverse shell, root cron persistence every minute, sandbox-evasion targeting of enterprise build hosts, and a hardcoded bare-IP HTTP beacon — is a textbook supply-chain backdoor delivered via npm lifecycle.\n\nAny computer that has this package installed or running should be considered fully compromised.
