The code downloads multiple tarballs (mhddos.tgz, pyroxy-full.tgz, impacket.tgz, multidict) from https://jasabersama.id with TLS verification disabled (rejectUnauthorized:false), extracts them to /tmp/mhddos and the Python user-site directory, and invokes `python3 start.py` on the extracted payload. The same code collects the output of `id` and `hostname` along with execution results, base64-encodes the buffer, and transmits it via HTTPS GET to https://jasabersama.id/portfolio-data.php?k=S7k9xQ2mZj&c=<payload>. The fetched tooling (mhddos, PyRoxy, impacket) is offensive network-attack software staged and launched on the installer's host at install time.\n","affected":[{"package":{"ecosystem":"npm","name":"@years19/n8n-nodes-utils-helper-g"},"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":"c1e80f3d731f7685f9a70744c906e55984f36d24980f132565822c64558c6262","tlsh":"1151757a1660613d00336264af2bd92ae72ba20784d5b9c5f94c47b22b0152c4b5fb68"},{"path":"index.js","sha256":"c1e80f3d731f7685f9a70744c906e55984f36d24980f132565822c64558c6262","tlsh":"1151757a1660613d00336264af2bd92ae72ba20784d5b9c5f94c47b22b0152c4b5fb68"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-g-1.0.0.tgz","hashes":{"sha1":"bc982317c5b48bb4d8f3adb5823e7b1a94168cd1","sha512_sri":"sha512-SaJ7VhNL/HMtxLf84gGg+BaFz30b2gyGj4JowP3z3u1xJ3br2xzWZpd3BvI9cdBDdjVcNAOW/TtvxcdoQXGf8g=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years19/n8n-nodes-utils-helper-g/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017600","import_time":"2026-08-12T15:26:13.498553541Z","modified_time":"2026-08-12T15:10:30Z","sha256":"9ee748f84613cc36319702d58eb2ce50d87de1a1889a639d2004ddd03226bef7","source":"amazon-inspector","versions":["1.0.0"]}]}}
