No hash or signature verification. Destination hostnames are assembled at runtime by joining split string arrays to evade static analysis, and a written state file plus environment-variable opt-outs (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) and comments referencing \"SHA-256 integrity check\" and \"session tracking\" frame the drop as telemetry, which does not match the package's stated Operations SDK purpose.\n","modified":"2026-08-05T13:36:01.840273493Z","published":"2026-08-05T12:34:58Z","database_specific":{"malicious-packages-origins":[{"sha256":"e8cd571b2f151fe07ba9e4be24c62290f79b73880ec1da77324b192a1b3af24f","source":"amazon-inspector","versions":["20.4.9"],"id":"IN-MAL-2026-014715","import_time":"2026-08-05T13:08:40.163127489Z","modified_time":"2026-08-05T12:34:58Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/statist-browser-typed-client-mb.product.operations/v/20.4.9"}],"affected":[{"package":{"name":"statist-browser-typed-client-mb.product.operations","ecosystem":"npm","purl":"pkg:npm/statist-browser-typed-client-mb.product.operations"},"versions":["20.4.9"],"database_specific":{"indicators":{"evidence_files":[{"sha256":"0dc0ff57fcbc1d0013f96006b136024cfe242c781aca191f240aa8878f28ce7c","tlsh":"79b1865615aa701d8bf0e7e08717581af65be6633380c2d8fb6c94945f7216483b2efc","path":"_bridge.js"}],"package_integrity":[{"filename":"statist-browser-typed-client-mb.product.operations-20.4.9.tgz","hashes":{"sha1":"c86a14b160afec7de2c2c877061ed43ffc38929a","sha512_sri":"sha512-8qzWoA3p9f/CKxnSSmgz+jcoTXRBoVnB8yqfu5XV22GN421MQf0i7yAI3prLSKBqJvJKnduXMSdgkeFqSjlQBA=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/statist-browser-typed-client-mb.product.operations/MAL-2026-12448.json","cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}]}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
