Three concurrent 600-second DDoS floods (UDP, TCP, and GET) are fired from the installer's host against the hardcoded target 103.118.252.21 on ports 80/443. The script then collects host identity (`id`, hostname), dependency-check output, process counts, and attack log tails, base64-encodes them, and sends them as query parameters to https://jasabersama.id/portfolio-data.php with a hardcoded key. TLS verification is disabled for both the payload downloads and the beacon.\n","modified":"2026-08-12T15:30:13.541055163Z","published":"2026-08-12T15:09:44Z","database_specific":{"malicious-packages-origins":[{"modified_time":"2026-08-12T15:09:44Z","sha256":"690b884eaa3ac12bdca74814577c4d42fb0811ee22ebc20687f809ad3e293755","source":"amazon-inspector","versions":["1.0.0"],"id":"IN-MAL-2026-017595","import_time":"2026-08-12T15:26:12.93199019Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years19/n8n-nodes-utils-helper-h/v/1.0.0"}],"affected":[{"package":{"name":"@years19/n8n-nodes-utils-helper-h","ecosystem":"npm","purl":"pkg:npm/%40years19/n8n-nodes-utils-helper-h"},"versions":["1.0.0"],"database_specific":{"cwes":[{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."}],"indicators":{"evidence_files":[{"sha256":"47924dadac91aeda94104bb167a64e883a3a149ca2b795eabef9c6caef32bafd","tlsh":"1b51a6f51521913c003311289f17e879e32fa20798a0fdd9fa8e56725f0161cd64fb78","path":"callback.js"}],"package_integrity":[{"hashes":{"sha512_sri":"sha512-pJ1jfdaQTz/jtcsMeVlmw923jbO9PyG/UT1mWQwLVBncNzASH9C9FjOvdoj+ydHYAVNrVwfQ2B+CAdbylxtNDQ==","sha1":"57fdd6e5f2452415cb1b1dfa7c2747eebcbe2724"},"filename":"n8n-nodes-utils-helper-h-1.0.0.tgz"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@years19/n8n-nodes-utils-helper-h/MAL-2026-13891.json"}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
