The mismatch between the declared trivial utility purpose and the install-time cloud-metadata scraping identifies the package as a decoy delivery vehicle for credential theft.\n","affected":[{"package":{"name":"time-utils-helper","ecosystem":"npm"},"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":"postinstall.js","sha256":"cd9315d4631bfde5bfe82042b45105c9f42839f41b7b39261e4358957a5f9f3a","tlsh":"195112fcb93578333f1e8a94f3ad6a0a8593dc9f4bf4eb0054b61d280c0cd413665a66"},{"path":"package.json","sha256":"de1b57b46cb7c80a618bc22c8cc864ff477cd7a125fc9eff9d40c7a2eda1727d","tlsh":"afd02b248a1145333ad09ae55a574845bb654e2b03047c1d53e7100c43cfbf284fe31e"}],"package_integrity":[{"filename":"time-utils-helper-1.0.0.tgz","hashes":{"sha1":"f3ecb62dc9e05b4f3f2a85da4718eb0d90e7abab","sha512_sri":"sha512-KtgvvxJiEmHLTr8ImC0l1gy3OpKgcESfppW+05PQhprh6ZbzFrmBa/tOrD7gVOi+Pb9kvAiR2yKLxse+bqJISg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/time-utils-helper/v/1.0.0"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-014629","import_time":"2026-08-05T09:28:32.256716735Z","modified_time":"2026-08-05T09:18:14Z","sha256":"93cbd818e3b29b2b7c9da6f48b3d82baae1af9bd0fa637a2848749bdfea86084","source":"amazon-inspector","versions":["1.0.0"]},{"id":"RLMA-2026-10799","import_time":"2026-09-24T09:21:35.874864524Z","modified_time":"2026-09-22T17:43:03Z","sha256":"930b9b1a1f30c53bad6b4d7ab51a91ab6ac49cc9ab5fda079cf74878df61f4b7","source":"reversing-labs","versions":["1.0.0"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"ReversingLabs","contact":["https://www.reversinglabs.com"],"type":"FINDER"}]}
