This fires automatically on `npm install` with no caller consent, leaks internal host and build-path identifiers in cleartext, and points at a non-publisher bare IP. The package itself is hollow — index.js is a one-line placeholder — and is published at the inflated version 99.99.1 by an anonymous author, the canonical shape of a dependency-confusion probe designed to be resolved ahead of a private internal package of the same name. The combination of the /depconf/\u003cpkgname\u003e/ URL path, the inflated version, and the placeholder body confirms reconnaissance intent: any organization with a private `abu-common-components` package will leak its existence and internal host fingerprints to the attacker on a single `npm install`.\n","modified":"2026-06-25T15:46:25.943006312Z","published":"2026-06-25T15:26:32Z","database_specific":{"malicious-packages-origins":[{"import_time":"2026-06-25T15:30:14.229048762Z","modified_time":"2026-06-25T15:26:32Z","sha256":"17e7b4ac8a492915d8475c73488b64236250746de410c705b7cc43c0656589be","source":"amazon-inspector","versions":["99.99.1"],"id":"IN-MAL-2026-007508"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/abu-common-components/v/99.99.1"}],"affected":[{"package":{"name":"abu-common-components","ecosystem":"npm","purl":"pkg:npm/abu-common-components"},"versions":["99.99.1"],"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":"package.json","sha256":"33711588dfc1fabfa1501cc942662b1a62847216ad5dc4ba720814c592fe517d","tlsh":"49f05c34e0285a733dd044b91975970b77c0ab87d794ac0d63e79c0827cd2b52167165"}],"package_integrity":[{"filename":"abu-common-components-99.99.1.tgz","hashes":{"sha1":"e3571f8e67ec6d5cf923db9070d1e923182034d4","sha512_sri":"sha512-40P25b6GjR77ePa9ooNrUqNBULEacPJwTu+77OOUMtjC2b9LqhqQ3quFMRN5ya78JDZ5ibnU526S1ghrrwycfg=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/abu-common-components/MAL-2026-6463.json"}}],"schema_version":"1.7.5","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
