The generic package name combined with the anomalous 4.999.0 version bump is the canonical dependency-confusion research/attack shape, where a high version number is published to a public registry to override a private internal package and cause the recon payload to fire in the victim's build.\n","modified":"2026-07-15T05:20:00.211930477Z","published":"2026-07-15T03:25:43Z","database_specific":{"malicious-packages-origins":[{"import_time":"2026-07-15T04:32:05.00816516Z","modified_time":"2026-07-15T03:25:43Z","sha256":"46b0bed6337ffe527af2615fed8ae1ecbb449f6a6cb00afa6381f7811ec88956","source":"amazon-inspector","versions":["4.999.0"],"id":"IN-MAL-2026-010599"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/leviosa86-test/v/4.999.0"}],"affected":[{"package":{"name":"leviosa86-test","ecosystem":"npm","purl":"pkg:npm/leviosa86-test"},"versions":["4.999.0"],"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":[{"tlsh":"bce0abc47aae1437b3c010819e31200bfe83db6a1ab1d8a4e20981763448b84b0a51e2","path":"src/poc/index.js","sha256":"a93d55cd8499780045f07b664b09d0eabe89dbf77b4e5e963c92d8572ca33290"}],"package_integrity":[{"hashes":{"sha512_sri":"sha512-8msHxrXPskhL8RymsF9e8lHFXs9+kiHTFPcv+ue8gf6M4m4EUp4o5pACH4IR1rsamGamlDHFUShMgDySu3i6TA==","sha1":"27f0faa2ac3e04da498c6b08e0eb61625e1fb7fd"},"filename":"leviosa86-test-4.999.0.tgz"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/leviosa86-test/MAL-2026-10636.json"}}],"schema_version":"1.7.5","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
