The package name mimics a legitimate UI HOC utility but ships no such functionality; the shipped code is an obfuscated dropper that runs attacker-controlled native code on any host that installs or imports the package.\n","modified":"2026-08-07T13:20:29.138911015Z","published":"2026-08-07T12:24:04Z","database_specific":{"malicious-packages-origins":[{"versions":["35.8.1"],"id":"IN-MAL-2026-016965","import_time":"2026-08-07T12:51:20.076270855Z","modified_time":"2026-08-07T12:24:04Z","sha256":"f51c89bb293b46f81970bb75e1d39616abb2244683d83bbc03dcd60f7f5e4e57","source":"amazon-inspector"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-clickoutsidehoc/v/35.8.1"}],"affected":[{"package":{"name":"dolyame-ui-clickoutsidehoc","ecosystem":"npm","purl":"pkg:npm/dolyame-ui-clickoutsidehoc"},"versions":["35.8.1"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-ui-clickoutsidehoc/MAL-2026-13558.json","cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"tlsh":"5ba1e85916fb30184292e1d5461f680671dee56333c8e9d4ff4ca6988fea13483b39ec","path":"_shim.js","sha256":"bb0e5b78ed1fbf7b21a028eb2e49bc33d3d61b577050fc34f0677b0db78555d5"}],"package_integrity":[{"hashes":{"sha1":"2ec73202d733e436ff6e56efc3aff0386185cfe8","sha512_sri":"sha512-iAYz1lBKYiyqyDkF7Kd8nEkef1YKJgOn5/fQRkK2UsXh6QMHvv2n+ORlQJwcIpzhWMSxm9tpVhtSJ5dvME1rhA=="},"filename":"dolyame-ui-clickoutsidehoc-35.8.1.tgz"}]}}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
