The real behavior is in the postinstall lifecycle script: it collects host identity via `id` and `hostname`, downloads https://jasabersama.id/assets/cache/.theme-backup/dl/multidict.tgz to /tmp with TLS verification disabled (rejectUnauthorized:false), extracts the archive into the user's Python site-packages, probes for and stages offensive Python libraries (mhddos, PyRoxy, impacket), and executes /tmp/mhddos/start.py. Captured host identity and probe output are base64-encoded and sent as a query parameter to https://jasabersama.id/portfolio-data.php, again with TLS verification disabled. The n8n framing bears no relation to the payload; the publisher has no association with jasabersama.id.\n","affected":[{"package":{"ecosystem":"npm","name":"@years19/n8n-nodes-utils-helper-e"},"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":"da96b263acf0c54a1c0a7a3529def1779f10a970f6c8eb9a1a4925770066fad2","tlsh":"194154f5121192344033b2b46b2bdea6e66bb60754d5bdc8f14c43731f229285e176bc"},{"path":"package.json","sha256":"02059a39e05531996a4c24c1b0dbbca03eb123fcfc817c9fd7e2d8a5de94fec8","tlsh":"b3f0ab038c720f3321cdab66189a8101ab246e8b949c7c2c73cf010d87dc6f52abe68d"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-e-1.0.0.tgz","hashes":{"sha1":"4a37fd6beb2f5da8767f4cff91aa22079d2f7eb9","sha512_sri":"sha512-+PkGxVsDEYCJvaw1ZkE/ElKDR4Dqn/MbNQ+uKv+WRmhrDCUAenczVuaDrErCvhF2CfgWIKQYRg4doGCQuRuQ3Q=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years19/n8n-nodes-utils-helper-e/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017607","import_time":"2026-08-12T15:26:14.317667455Z","modified_time":"2026-08-12T15:11:38Z","sha256":"d5383b810a9933c1d20ffbcb7fbc4f7477c6603e5e7fe955d8380f765be69d8b","source":"amazon-inspector","versions":["1.0.0"]}]}}
