The install-cb.js script issues an HTTPS request and a DNS lookup to a Burp Collaborator subdomain under oastify.com (nc-verify-127942.owoemjgpf2c4qxqet92hexzvym4dsq6skvoa2cr.oastify.com), which confirms code execution on the installer's host and leaks install-side network identifiers (source IP, resolver) to an operator-controlled out-of-band endpoint. The package's own metadata labels it as a proof-of-concept for RCE verification; installing it in a normal developer or CI environment fires the beacon without any user interaction.\n","affected":[{"package":{"ecosystem":"npm","name":"nc-verify-127942"},"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":"install-cb.js","sha256":"165f92acd719f30efc0206ff9c3b4144f6108bc02c99ca93c29f12b1a5ff07aa","tlsh":"8a01d0fe38e3a2106da47aa4c06fc960665fd054a284c486a8cf4120362511d2336c5c"},{"path":"package.json","sha256":"40b6cd19bf283cdd7c4c858450cfad67095236ee6621cdda7eb81720ec6d590d","tlsh":"64e0c2248c2166333dc09ae6092a4556733dbd2e1149b55a22c31504829aab6467e31e"}],"package_integrity":[{"filename":"nc-verify-127942-1.0.0.tgz","hashes":{"sha1":"90b5de80ff58e93f1f1e069b83e9d1d62fa0fba7","sha512_sri":"sha512-0UDcvzS0mCJX3W9lpMOfyMBLoPRlYTO5HLJxAHUMrbDeVoUo1qCwS5ZVHCOzJ3k+2TxhDnvgBzD/pgQ24JiY3A=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/nc-verify-127942/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017668","import_time":"2026-08-13T20:49:27.539146485Z","modified_time":"2026-08-13T20:42:13Z","sha256":"3ea69188e179cd73aa9f200d63e8faceb5d3aae622a8fe2d86bf7ae761b5f1e0","source":"amazon-inspector","versions":["1.0.0"]}]}}
