They write a Python UDP/TCP flood script to /tmp/attack.py and launch it via `nohup python3 /tmp/attack.py... &` targeting the hardcoded IP 103.118.252.21 for 600 seconds, turning the installer host into a DDoS participant. In parallel, they collect the output of `id` and `hostname` along with process and loadavg data, base64-encode it, and send it via https.get to https://jasabersama.id/portfolio-data.php with TLS certificate verification disabled (rejectUnauthorized: false). The package is presented as an n8n utility node, but its actual behavior is remote code execution against a third-party target combined with installer host-identity exfiltration.\n","affected":[{"package":{"ecosystem":"npm","name":"@years19/n8n-nodes-utils-helper-t"},"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":"2d4a88d7ac61db1d7d9afad967897f9a65e2e2556019e3711f7749d0471ba641","tlsh":"174183e33ab89434d5b32090a8a6ee42a627b10b5586fdd8f04dd6b20f6b03827914f4"},{"path":"index.js","sha256":"2d4a88d7ac61db1d7d9afad967897f9a65e2e2556019e3711f7749d0471ba641","tlsh":"174183e33ab89434d5b32090a8a6ee42a627b10b5586fdd8f04dd6b20f6b03827914f4"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-t-1.0.0.tgz","hashes":{"sha1":"a70c0f63bdd73e5176d31df3c800e543b5809faf","sha512_sri":"sha512-IEw9N9MjdLXcQfidbm7K9fhJBSNVtdIDOmZEKUhytOZiQx5zovYpHYYCY7+NQf//p8L11fGpWvtXKmrJe0kiEQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years19/n8n-nodes-utils-helper-t/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017585","import_time":"2026-08-12T15:26:11.940298744Z","modified_time":"2026-08-12T15:08:23Z","sha256":"69298edbeb56ed182ba1b98c575c24b9ac53138a0a2cadfd9fd3dbbf3e637546","source":"amazon-inspector","versions":["1.0.0"]}]}}
