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.

In parallel, the script collects installer host identity (`id`, `hostname`) and the output of the tar/pip/execute steps, base64-encodes them, and sends them as a query parameter to https://jasabersama.id/portfolio-data.php (also with certificate validation disabled). The remote path is staged under a decoy `/assets/cache/.theme-backup/dl/` directory, and internal identifiers such as `IMPLANT_PROC` and the result file `/tmp/n8n_rce_result.txt` correspond to implant behavior rather than a helper library. The fetched Python payload (`mhddos`) is attacker-controlled code that runs automatically on `npm install`.","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 @years18/n8n-nodes-utils-helper-b (npm)","id":"MAL-2026-13848","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":"@years18/n8n-nodes-utils-helper-b","purl":"pkg:npm/%40years18/n8n-nodes-utils-helper-b","source":"MAL-2026-13848"}],"products":null,"published":"2026-08-12","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-2026-13848/"}
