There is no hash or signature verification. Additional anti-analysis features are present: hostnames are assembled at runtime to evade static string scans, dropped files use benign-looking diagnostic/cache names, a marker file.analytics_state is written, and telemetry-opt-out environment variables (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) are honored as a cover story for the binary drop. The Cloudflare Workers hosts and DNS fallback domains have no relationship to any legitimate publisher of this package.\n","modified":"2026-08-05T10:07:09.967760618Z","published":"2026-08-05T09:13:43Z","database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-014598","import_time":"2026-08-05T09:28:29.080779207Z","modified_time":"2026-08-05T09:13:43Z","sha256":"0870bb9f10cb88f264e25b839c6001a3b2c7d77777115871ba0e3c6f61ddb84b","source":"amazon-inspector","versions":["20.6.6"]}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/twork-products-taiga2-products-mobile/v/20.6.6"}],"affected":[{"package":{"name":"twork-products-taiga2-products-mobile","ecosystem":"npm","purl":"pkg:npm/twork-products-taiga2-products-mobile"},"versions":["20.6.6"],"database_specific":{"indicators":{"evidence_files":[{"path":"_init.js","sha256":"3710751c3316e2d2ec29673a062c3edf9a8bc18154ba82f974e6f1ad1b51f99a","tlsh":"e2a1869a02a570194bb0ebe0c61b8425f66af2533780d2d0f79ca5845f765248372efc"}],"package_integrity":[{"filename":"twork-products-taiga2-products-mobile-20.6.6.tgz","hashes":{"sha512_sri":"sha512-0hZV+54g66XsZpP5TIcLZZa5m1chzfsUC6grcYdA4CpWCp+6ZaCoQv5j6XjnjX4Y+n1lHaIIYKkxy7ocg5NKXA==","sha1":"8057241c5bc5c361095a872a9ecd31ae673ace27"}}]},"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/twork-products-taiga2-products-mobile/MAL-2026-12306.json"}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
