The downloaded bytes are written to /var/tmp or %TEMP% under disguised names (.cache_<hex> on Unix, dotnet_diag_<hex>.exe on Windows), chmod 0755, and spawned detached via spawn(\"/bin/sh\", [\"-c\", fp+\" &\"], {detached:true}) or spawn(\"cmd\",...). Destination hostnames are reconstructed at runtime by splitting/joining string fragments (e.g. [\"oob-worker.cf101-adf\",\".workers.d\",\"ev\"].join(\"\")) to evade static analysis. Comments and env-var checks (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) mimic telemetry as cover. The advertised purpose is a React UI components library, which does not require fetching and executing native binaries from third-party Cloudflare Workers infrastructure.\n","affected":[{"package":{"name":"ded-aa-liza-ui-components","ecosystem":"npm","purl":"pkg:npm/ded-aa-liza-ui-components"},"versions":["35.8.7"],"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":"_helpers.js","sha256":"708eee3139cea3c6e964c07c3bbf1b33b46793ed1ffe2ae31c16eddf27d2fdac","tlsh":"07a1959a06b670188bb09bf4c7174415f65be6633781c288fb5ca9945fb712483b2efc"}],"package_integrity":[{"filename":"ded-aa-liza-ui-components-35.8.7.tgz","hashes":{"sha1":"cffdb14e1fa2eec9a745fbaa6f986b07be129351","sha512_sri":"sha512-IFDIVOul2m+F6ZZLwAjv22gVS0ER7JuNXNMfCGbDeWvwzrFD3skEO3S+u1jeHmvxVSZi1aNyTVeNv9wiU85YOQ=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/ded-aa-liza-ui-components/MAL-2026-12672.json"}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/ded-aa-liza-ui-components/v/35.8.7"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015100","import_time":"2026-08-05T14:20:02.043933222Z","modified_time":"2026-08-05T13:56:19Z","sha256":"a328f8fbefe24a810c8fe1c0249029992137bec024cab060df03d88347b5185b","source":"amazon-inspector","versions":["35.8.7"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
