On `npm install`, callback.js fetches two tarballs (impacket.tgz, pyroxy.tgz) over HTTPS with TLS verification disabled from jasabersama.id/assets/cache/.theme-backup/dl/, extracts them into the installer's Python user site-packages so any subsequent Python import runs attacker-controlled code, and probes /tmp/mhddos/start.py (MHDDoS DDoS tooling). The same script collects `id` and `hostname` command output plus install-step status, base64-encodes the buffer, and sends it via HTTPS GET to https://jasabersama.id/portfolio-data.php as a URL parameter, indexing compromised hosts. The declared package purpose does not match the shipped behavior; the host is publisher-mismatched and TLS verification is disabled.\n","affected":[{"package":{"ecosystem":"npm","name":"@years18/n8n-nodes-utils-helper-x"},"versions":["1.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"callback.js","sha256":"5210b59af493bc28c93fb1b6d76b888887b673943f7e945f32e1a277fcc3acdd","tlsh":"f54155b912619235803272789f1bdd6ae66fb20354d5b9c9f24c43732f1282c5e1aab8"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-x-1.0.0.tgz","hashes":{"sha1":"e0f06cc8b44d0cda56541675d7e112ccb20cc3d2","sha512_sri":"sha512-i60ap78bFd/jZCPB4Ax3P2QkLdk/0NhN7kRoDBd/yjLKywCZw5qE9VInje3q9viidVsND+PQot9bxG7D/QFxpQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years18/n8n-nodes-utils-helper-x/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017390","import_time":"2026-08-12T12:24:08.798921294Z","modified_time":"2026-08-12T12:14:55Z","sha256":"6db9e566808d6a2ce38311e17939cd39ba94fc191cf5c44ab7b08b369840ba08","source":"amazon-inspector","versions":["1.0.0"]}]}}
