All destination hostnames are assembled at runtime via array.join to defeat static string matching. The fetched bytes are written to a disguised path in /tmp or %TEMP% using cover-story names such as.cache_<uid>, dotnet_diag_<uid>.exe, and a.analytics_state marker file, chmod'd 0755, and executed detached via spawn('/bin/sh', ['-c', fp + ' &']) or cmd.exe /c start /b, with no hash or signature verification. Execution is gated by DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK env vars and a filesystem TTL marker to avoid re-running in analysis environments. The advertised UI-library purpose is unrelated to any of this behavior.\n","affected":[{"package":{"ecosystem":"npm","name":"dolyame-ui-menu"},"versions":["35.6.1"],"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":"_polyfill.js","sha256":"aba749ad09e63adf71131b3704617ab455b42a95770d33b7674fcfe82c1a0dad","tlsh":"eba1a65a126a70084b70dbe4cb174416f65bf6633780c689fb9c69981f7212483b2efc"}],"package_integrity":[{"filename":"dolyame-ui-menu-35.6.1.tgz","hashes":{"sha1":"d7a399ce3c54b4bd8dd314b5f313f0601a06eb77","sha512_sri":"sha512-nQgsUCzllBfiHeR8ays+XMSc4zjOvtso5yY0Sy3yGlp0y+KvBMHQcor6UkoAbiH/qaUY86WguUtRp2QHSHCsrw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-menu/v/35.6.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015607","import_time":"2026-08-05T15:20:00.061744217Z","modified_time":"2026-08-05T15:12:28Z","sha256":"cecad37efa23b83ead95d73e1b0ef07dbb8473dfd76645f4ceed5cf7939653f4","source":"amazon-inspector","versions":["35.6.1"]}]}}
