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-2026-5986/ (Markdown: https://insights.sbomify.com/MAL-2026-5986/index.md)","id":"MAL-2026-5986","markdown":"https://insights.sbomify.com/MAL-2026-5986/index.md","name":"MAL-2026-5986","record":{"aliases":["GHSA-p3jc-qrj7-hj68"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"package.json declares a postinstall hook (\"postinstall\": \"node run.js\") that auto-executes on install. The package ships beacon scripts (beacon14.js, beacon_linux.js) that import child_process and http/os, run shell commands such as whoami, read process.env, process.platform, os.hostname(), os.platform(), and transmit the collected host/identity data via http.request GET/POST to a remote endpoint. The data flow (system enumeration -\u003e outbound HTTP) and the install-time auto-execution together constitute a credential/host-info exfiltration beacon. Installer harm: any machine that runs `npm install npm-sandbox-ping-r9t2` will silently execute these beacons and leak local identity/environment information to a remote endpoint.\n\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer.
