{"id":"MAL-2026-13862","summary":"Malicious code in @years18/n8n-nodes-utils-helper-r (npm)","details":"\n---\n_-= Per source details. Do not edit below this line.=-_\n\n## Source: amazon-inspector (be4bb7a1bd57477bf3cbbb1ccc9b76a2ed8b96a8117e0a4cad882b76404c86fb)\n@years18/n8n-nodes-utils-helper-r ships a postinstall script that, on `npm install`, downloads a tarball from https://jasabersama.id/assets/cache/.theme-backup/dl/pyroxy-full.tgz over TLS with certificate verification disabled and extracts it into the installer's Python site-packages directory, then verifies the drop by executing `python3 start.py` from /tmp/mhddos. The dropped payload is the PyRoxy / MHDDOS DDoS attack framework. The same postinstall collects the output of `id` and `hostname`, base64-encodes the result, and sends it via HTTPS GET (certificate verification disabled) to jasabersama.id/portfolio-data.php with a hardcoded key parameter. The package presents itself as an n8n community utility node, but the delivered payload is unrelated offensive tooling.\n","modified":"2026-08-12T12:30:15.049943668Z","published":"2026-08-12T12:15:45Z","database_specific":{"malicious-packages-origins":[{"modified_time":"2026-08-12T12:15:45Z","sha256":"be4bb7a1bd57477bf3cbbb1ccc9b76a2ed8b96a8117e0a4cad882b76404c86fb","source":"amazon-inspector","versions":["1.0.0"],"id":"IN-MAL-2026-017396","import_time":"2026-08-12T12:24:09.455938425Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years18/n8n-nodes-utils-helper-r/v/1.0.0"}],"affected":[{"package":{"name":"@years18/n8n-nodes-utils-helper-r","ecosystem":"npm","purl":"pkg:npm/%40years18/n8n-nodes-utils-helper-r"},"versions":["1.0.0"],"database_specific":{"indicators":{"evidence_files":[{"tlsh":"a63167f9126191344573b2a46f1bdd67d63bb20354c9fec4f24c43731f129285d676a8","path":"callback.js","sha256":"fdc80c96df674dc6d83aadcb833ac4cac14994c0b51f725c4573fd179fe6b7e4"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-r-1.0.0.tgz","hashes":{"sha512_sri":"sha512-KVDJo8qWMiZcAI+Ggij918ya7M5SzyAw0nkkEJby6RDCMJUA7tL/XH9emNf9YK1tLex8G0WyEPmDV5DVACe5SQ==","sha1":"2eb389e15590d9cf0d6105672207e742f1cb958e"}}]},"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@years18/n8n-nodes-utils-helper-r/MAL-2026-13862.json"}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
