MAL-2026-5981

Summary: Malicious code in metrics-probe-64b2 (npm)

Details: Source: amazon-inspector (cae901b673ee21724897f69c782eb2808c55c2722bacc9912a4a3e60f7019883) package.json declares a postinstall hook ("postinstall": "node run.js") that executes run.js automatically on every npm install. run.js imports os, fs, http, https, and child_process, reads host identifiers including os.hostname() and os.platform(), reads files from disk via fs.readFileSync, and issues outbound HTTP POST requests carrying that data. The package's stated name ("metrics-probe") with a random hex suffix, combined with an install-time host-fingerprinting beacon and no library functionality, matches the shape of an installer-side reconnaissance / data-exfiltration payload that fires automatically on `npm install` without any user action. Source: ghsa-malware (e74624577c3b03a5250f5be13a89c3ba4495967d8389dbd384525e72c15c2bb0) Any 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. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
