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.

The.js-suffixed data file, the double-encoded payload smuggled as product 'mark' fields, and the mismatch between the stated purpose (random data generation) and the presence of dynamic code execution together form a loader/dropper pattern: any consumer that calls the advertised API executes attacker-authored JavaScript in the calling process. Declared dependencies include axios and python-shell, consistent with a stager that fetches or spawns further payloads once the decoded code runs.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in txs-runner-sdk (npm)","id":"MAL-2026-14199","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"txs-runner-sdk","purl":"pkg:npm/txs-runner-sdk","source":"MAL-2026-14199"}],"products":null,"published":"2026-08-19","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-14199/"}
