No native source is shipped in the tarball and the fetched bytes are opaque. lib/telemetry.js, re-exported by the package's main entry, duplicates the same dropper primitives (base64-decoded chunks written to disk, chmod 755, /bin/sh -c spawn) behind an \"Analytics SDK\" cover story, ensuring execution persists even if _init.js is stripped. Runtime string reassembly of module names (require(\"child_\"+\"process\")) and destination hosts, plus opt-out env-var gates (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) and a TTL cache file, are used to evade static analysis and hide repeat executions.\n","affected":[{"package":{"ecosystem":"npm","name":"dolyame-ui-inputrange"},"versions":["35.8.1"],"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":"_init.js","sha256":"a9ab753045073c1a570f3c4b7dd576d85bcb8b6dd86282bd7d165e68904e8655","tlsh":"02a1c55516fa70280a92b1d8c41f9826709ffa9336c1d9c4fb4c66949fd762883f29fc"},{"path":"lib/telemetry.js","sha256":"4c7322e0a5414c157bf4b8ebb45450dcca0b0ee5b41a5f0e7a9bbc4e10d228b4","tlsh":"2073304966fb10214263b0685fab40437635c4072a4aed5dba9c43ec9f8db3896f1fb9"}],"package_integrity":[{"filename":"dolyame-ui-inputrange-35.8.1.tgz","hashes":{"sha1":"d4e08a24db24509fe2eab1f67ca201b24ad7ce01","sha512_sri":"sha512-Ju9qP4SUkuEWpQcQ0OA5l6pW7SXwZrgisdngMkEViSORzI/yk5pxQpXNBaB/3SJsrPlqjVsJMpqdsbienGZDwA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-inputrange/v/35.8.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-016997","import_time":"2026-08-07T12:51:21.485773179Z","modified_time":"2026-08-07T12:28:43Z","sha256":"aae096235cf72db7f2e9908e53fa5a6e7c87718539a9e3452e0e34f7345ca80f","source":"amazon-inspector","versions":["35.8.1"]}]}}
