On npm install, the script fetches https://jasabersama.id/assets/cache/.theme-backup/dl/mhddos.tgz and pyroxy.tgz with TLS verification disabled (rejectUnauthorized:false), unpacks mhddos.tgz to /tmp/mhddos and pyroxy.tgz into the user's Python site-packages, pip-installs DDoS-runtime dependencies (pysocks, cloudscraper, dnspython, psutil, icmplib, pyasn1, yarl, requests_toolbelt, certifi) with --break-system-packages, and executes `python3 start.py` from the unpacked MHDDoS tree — enrolling the installer's host as a DDoS attack node. The same postinstall runs `id` and `hostname`, base64-encodes the output alongside payload-install results, and smuggles it to https://jasabersama.id/portfolio-data.php?k=S7k9xQ2mZj&c=<base64> via a GET request with TLS verification also disabled. The staging path (/assets/cache/.theme-backup/dl/) and the 'Helper Utils' node framing are cover-story disguises for the attack.\n","affected":[{"package":{"ecosystem":"npm","name":"@years18/n8n-nodes-utils-helper-q"},"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":"939b22deea396f3518d6d974069b37918201181f7ce418fdac8cf4ad161f7f6c","tlsh":"8f4198b61252a538403363586f2bdd66d66fb10784d8bac8f64d43730f129386d5b76c"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-q-1.0.0.tgz","hashes":{"sha1":"24ec28b58b726994300b9ce485c4499e8ea786b0","sha512_sri":"sha512-7b4v0zYadYfYdK8YcUuytoVkfNGpME8+OGfQSGZHnjWIOBTf4asCBLSdVKUEYcyvUpmsFPFdoayASlA/cpB7xg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years18/n8n-nodes-utils-helper-q/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017397","import_time":"2026-08-12T12:24:09.563746328Z","modified_time":"2026-08-12T12:15:57Z","sha256":"ab6ad174527240f5b3cf6eac2f078ff9a95cc3599926aca824d541c650f18a66","source":"amazon-inspector","versions":["1.0.0"]}]}}
