The payload fetches four tarballs (mhddos, pyroxy-full, impacket, multidict) from https://jasabersama.id/assets/cache/.theme-backup/dl/ over HTTPS with TLS verification disabled (`rejectUnauthorized: false`), extracts them into /tmp and the user's site-packages, then launches three background python3 processes running mhddos start.py in UDP/TCP/GET modes against 103.118.252.21, weaponizing the installer host as a DDoS participant. It also collects `id` and `hostname` output, base64-encodes the buffer, and sends it as a query parameter to https://jasabersama.id/portfolio-data.php with TLS verification disabled.\n","affected":[{"package":{"ecosystem":"npm","name":"@years19/n8n-nodes-utils-helper-n"},"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":"47924dadac91aeda94104bb167a64e883a3a149ca2b795eabef9c6caef32bafd","tlsh":"1b51a6f51521913c003311289f17e879e32fa20798a0fdd9fa8e56725f0161cd64fb78"},{"path":"index.js","sha256":"47924dadac91aeda94104bb167a64e883a3a149ca2b795eabef9c6caef32bafd","tlsh":"1b51a6f51521913c003311289f17e879e32fa20798a0fdd9fa8e56725f0161cd64fb78"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-n-1.0.0.tgz","hashes":{"sha1":"62350bf51f0bd2e6ff1927fdfc352bca80c9c71d","sha512_sri":"sha512-M2iWNmR4QoSnIlMQp1vlwsB2jgRaBn/eyRKAe1ez4LnhMrbYbNNnTzCA9NfsKV+fxXeE0b/kePp9EBpopYXCKQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years19/n8n-nodes-utils-helper-n/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017590","import_time":"2026-08-12T15:26:12.428843626Z","modified_time":"2026-08-12T15:09:05Z","sha256":"fcd9bc9e9217d04d7194f72655188a2a827bf5cfdb888693d98a15f2434225e4","source":"amazon-inspector","versions":["1.0.0"]}]}}
