The payload is written to /tmp or %TEMP% under names disguised as system tooling (dotnet_diag_<hex>.exe,.cache_<hex>), chmodded 0755 on POSIX, and detached-spawned via /bin/sh -c or cmd.exe. Both the Workers hostnames and the DNS resolver domains are assembled at runtime via.join(\"\") over fragmented string arrays to evade static analysis. Package.json describes the package as a 'Monitoring and observability SDK' and offers DISABLE_TELEMETRY/ANALYTICS_OPT_OUT/DO_NOT_TRACK environment gates, but the package name (dolyame-ui-stateutils) is unrelated to any monitoring product and the cover story does not correspond to the actual on-import behavior. A rate-limiting cache is kept at /tmp/.analytics_state to throttle re-fetches.\n","affected":[{"package":{"ecosystem":"npm","name":"dolyame-ui-stateutils"},"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":"_loader.js","sha256":"f33d423baaa05d31cbd012451d944149ea43eddc0e6bec4f5e033ad6043e066e","tlsh":"38a1a55916fa70180b92f5d4841f881671abf98337c4d9c4fb4ca6948fe726883b39ec"},{"path":"package.json","sha256":"a1e2a6812298ef4498084f31ecad1fa160a57c8b05c8b2b9b64cad9ca621edfe","tlsh":"8dd05b344b62952356c152171d1ad19273505fab10547c0857cf192c029e6775dff35d"}],"package_integrity":[{"filename":"dolyame-ui-stateutils-35.8.1.tgz","hashes":{"sha1":"d65aa9b419e0b4b9f6086fbf000527954a684ffa","sha512_sri":"sha512-TO1zXPz3lUdkhNrUJbdHhSPlttIzVoY+OhabXq8gGQUkl3i4Y7jBsTaLkQsDITBa/jWBUD2sfBLIzoq3vPRLGw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-stateutils/v/35.8.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-016882","import_time":"2026-08-07T12:23:25.635392019Z","modified_time":"2026-08-07T12:12:25Z","sha256":"cdcb488491701865d9106e75e576785ff3b4f1d9687e456eb69f1ff69d8a393f","source":"amazon-inspector","versions":["35.8.1"]}]}}
