The same script collects host reconnaissance (id, hostname, sudo -n -l, ls -la /var/run/docker.sock, docker ps, /etc/hosts, internal name resolution for nexus.local), base64-encodes the output, and sends it over HTTPS to jasabersama.id/portfolio-data.php with certificate verification disabled (rejectUnauthorized:false). The exfil URL also carries a c= parameter whose value is a shell command (echo <b64> | base64 -d >> /tmp/n8n_rce_result.txt), consistent with a server-side command handler at the C2 endpoint. In addition, nodes/PwnNode.node.js exposes an n8n node whose execute() runs `id; hostname; uname -a; ls -la /home; ls -la /` via child_process.execSync and returns the output as node JSON (pwned:true), providing a post-exploitation primitive to any workflow that uses the node.\n","affected":[{"package":{"ecosystem":"npm","name":"@years17/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":"2adf8b78ec9205232c34c87fb59a5850f107f06a448df2b105b4a74a8ef9ae3f","tlsh":"2f2146f532785d708bf4c5931d5f95b6f49b910316b278c4e0cc48a52bc799846329bd"},{"path":"nodes/PwnNode.node.js","sha256":"b4b05aecc01697e3bb67ad3be71d575674cc2ee0cbd81e01985289242f4d4059","tlsh":"fe111ef7adb6e2600092b4d75b07a1022822c3172725bc79ba8c46534f4894ca7b1ef8"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-g-1.0.0.tgz","hashes":{"sha1":"6f439a4ace520c09d0a874d9159d4856260544e0","sha512_sri":"sha512-Wv9qKBP0t3zgAuvMdI4Lwd7d9bSL8yWiKUvMoXI6weQHu4YwVclGdk07YvdT481696CJnDE8Y6YrQg0ANjDwXQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years17/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-2026-017555","import_time":"2026-08-12T12:51:49.947001085Z","modified_time":"2026-08-12T12:38:06Z","sha256":"3685924a9f7a3a8bbccd7521020a9f1e7ae208f1b991805b2861e4c289a6eaa3","source":"amazon-inspector","versions":["1.0.0"]}]}}
