The fetch-and-execute path has no pinning, no hash verification, and runs over an unauthenticated network retrieval. package.json also declares a self-referential dependency on `internallib_v275@^1.0.0`, a dependency-confusion shape consistent with a package targeting an internal registry namespace so that resolution against the public registry pulls this backdoor into internal builds.\n\n## Source: ghsa-malware (7e73d7869fce3c750cb3bdd88167659dd362d142c79a91f25408221ebacdf3e6)\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.\n","affected":[{"package":{"name":"internallib_v275","ecosystem":"npm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["1.0.3"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"index.js","sha256":"359d2ba4641af6b23fa4f22d18bb06217eb0eb9edaff667bd55b0b72887f2a56","tlsh":"c3d022aa06a010bdab4021e0de02f0a6a8178ca026b880f0d5484387008295e325f8ee"},{"path":"package.json","sha256":"3567efa24db20b2392139a22ebf45e9cd276ba806fc24c6d9bf3121bea769ae9","tlsh":"eed05e3059625db351c5136a2cb98457b2a18e2f4456bc0857cb592c41cf6f7a8fd39c"}],"package_integrity":[{"filename":"internallib_v275-1.0.3.tgz","hashes":{"sha1":"13a87a1beebc125d1c95ef4d50b6e35031b7c348","sha512_sri":"sha512-8Y0dwhVAxi+jxajFknlNViZ317Fabtt8u3l96Cr9kZ+540IbxUpjoVbVl4DcF1rce6OfVhViEl0qG0feASNRqw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/internallib_v275/v/1.0.3"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-f6rc-jhj3-4p2w"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-020969","import_time":"2026-10-04T23:40:46.945774819Z","modified_time":"2026-10-04T23:27:48Z","sha256":"80c1c6d383b3defb01da235e39e08ce56276d887e63d900aea2ee689836f71b4","source":"amazon-inspector","versions":["1.0.3"]},{"id":"GHSA-f6rc-jhj3-4p2w","import_time":"2026-10-05T18:34:10.830295386Z","modified_time":"2026-10-05T17:27:36Z","ranges":[{"events":[{"introduced":"0"}],"type":"SEMVER"}],"sha256":"7e73d7869fce3c750cb3bdd88167659dd362d142c79a91f25408221ebacdf3e6","source":"ghsa-malware"}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
