The script runs `id`, `hostname`, and WSL detection, reads the host SSH public key fingerprint from /etc/ssh/ssh_host_ed25519_key.pub, base64-encodes the collected data, and sends it via HTTPS GET to jasabersama.id/portfolio-data.php with TLS verification disabled (`rejectUnauthorized: false`). It also decodes a bundled OpenSSH ed25519 private key to /tmp/pk (chmod 600) and iterates `ssh -i /tmp/pk` login attempts against 127.0.0.1/localhost on ports 22495 and 22 as devuser/ubuntu/runner/node/root/chris/user, executing `id; hostname` on any account that accepts the key. The C2 URL path `/portfolio-data.php?k=S7k9xQ2mZj&c=<url-encoded shell command>` is shaped as a command channel, indicating the endpoint is dual-use exfiltration and remote-execution infrastructure.\n","affected":[{"package":{"ecosystem":"npm","name":"@years20/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":"8176be617df1750652d87e367cc3b6d871fbef43b371472f7976369db53db978","tlsh":"325198f851a0a53422b360b75dbadc15d5bffa02518addc8714d0b335fd6c9809336b8"},{"path":"index.js","sha256":"8176be617df1750652d87e367cc3b6d871fbef43b371472f7976369db53db978","tlsh":"325198f851a0a53422b360b75dbadc15d5bffa02518addc8714d0b335fd6c9809336b8"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-e-1.0.0.tgz","hashes":{"sha1":"e616b6e4b8f50c8a14e526895b9b9c38fc5b90e6","sha512_sri":"sha512-U0v9UZ7c5r262Kzyyo+ZK9e7zLIpYQZS44S9wdfe4hzUuVNVYAIAevsd0T/PCWnBKFGC8z9njhSEabOE4mXAmA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years20/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-2026-017581","import_time":"2026-08-12T15:26:11.654464198Z","modified_time":"2026-08-12T15:07:49Z","sha256":"89d61386ef6d8694ecf5f0578b5fe77156f475f76a8e97a1b2e834821cfbe0df","source":"amazon-inspector","versions":["1.0.0"]}]}}
