No signature or hash verification is performed; filenames masquerade as system caches; a TTL marker rate-limits execution; environment-variable checks are used as evasion; and a DNS TXT covert channel serves as a fallback delivery path. The fetch host is reconstructed at runtime with no legitimate purpose, and the destinations are not the package's publisher.\n","affected":[{"package":{"ecosystem":"npm","name":"delivery-ci-unit"},"versions":["35.9.3"],"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":"_loader.js","sha256":"15aa03b434cda85a1b998291f8cebd5a15e41e7f66703536cb29570b1acbd22d","tlsh":"69b1965a126630284bb09be4c71b4416f65ff6633380c294fb6ca9951f73124c2b2efd"}],"package_integrity":[{"filename":"delivery-ci-unit-35.9.3.tgz","hashes":{"sha1":"685c61e3b5d9e03ae4e9d4dfe7f8d2d55b83da1d","sha512_sri":"sha512-PpITXyz5uUgh72KVH1GwMWyDSaQgw+Hl6yZkR7CqPzzUmsB3mfZlAXf8RZq/76m2Jk/gcRk/DjcyzwP30BWMiQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/delivery-ci-unit/v/35.9.3"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015094","import_time":"2026-08-05T14:20:01.321279048Z","modified_time":"2026-08-05T13:55:26Z","sha256":"69ab1e8e2553a7469b1ce9a50549b0f1cb964160096693715d10643a853eade4","source":"amazon-inspector","versions":["35.9.3"]}]}}
