On install, callback.js fetches two tarballs from jasabersama.id over HTTPS with TLS verification disabled (rejectUnauthorized: false), extracts one to /tmp/mhddos and the other into the user's Python site-packages, installs a list of Python DDoS-support dependencies via pip with --break-system-packages, then executes `python3 start.py` from the extracted MHDDoS archive. The same script runs `id` and `hostname`, base64-encodes the output along with install-progress markers, and sends it via HTTPS GET to jasabersama.id/portfolio-data.php with TLS verification disabled. The declared n8n utility purpose is a cover story for the install-time payload.\n","affected":[{"package":{"ecosystem":"npm","name":"@years18/n8n-nodes-utils-helper-o"},"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"},{"path":"package.json","sha256":"e921be08432c356ec704a188a9eb8c4fccad9a5f800680358d24c5df0f1813bd","tlsh":"13f0ec128d724f3321cd6b66585941416a246d97949c7c2873cf010d87986b519bd699"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-o-1.0.0.tgz","hashes":{"sha1":"217ea54e83ffac03052e8113535a789059c89b1c","sha512_sri":"sha512-BeSKZ/pIyxy+otDBXdnPzkZyLx89B66IvQQmPHBEELc4kXfLH0dK8Xp/bSjxolzbDk9jFoQVp+SJQIEgGVx0YA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years18/n8n-nodes-utils-helper-o/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017398","import_time":"2026-08-12T12:24:09.676476075Z","modified_time":"2026-08-12T12:16:04Z","sha256":"5b7ec0fd707d50145d85051b5c960139ebe64dc5f12c89ee22ecfa8402d169c4","source":"amazon-inspector","versions":["1.0.0"]}]}}
