Hostnames are assembled at runtime via array.join() to defeat static analysis. The fetched bytes are written to a randomized tmp path mimicking a diagnostic tool (/var/tmp/.cache_<hex> or dotnet_diag_<hex>.exe), chmodded to 0755 on POSIX, and spawned detached via cp.spawn(\"/bin/sh\",[\"-c\",fp+\" &\"],{detached:true}).unref(). Cover-story comments in setup.js reference 'analytics_state' and 'Content-type negotiation'. The package name impersonates a payments-UI library, but the shipped code has no such functionality.\n","affected":[{"package":{"ecosystem":"npm","name":"dolyame-ui-island"},"versions":["35.7.4"],"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":"setup.js","sha256":"ade98d431bd52e63c6c77a69d64f6f811e5c74ca3826f995bd7cc1b0b75b437a","tlsh":"23a1969a16a670198bb0dbf486174416f657e6a33380c1d4fb5ca9985f73124c372efc"}],"package_integrity":[{"filename":"dolyame-ui-island-35.7.4.tgz","hashes":{"sha1":"00c1c0024942ffdde3dd2783640f4334394c0c00","sha512_sri":"sha512-WrwTwxO+NfMfaXOlWo6wz9Yx64oF6RaO0iVIuA9GE50mGKf7V3hGqrXObHv/nzV321U8+sLJMOvju/ymt6iAHA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-island/v/35.7.4"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015616","import_time":"2026-08-05T15:20:00.364005163Z","modified_time":"2026-08-05T15:13:43Z","sha256":"4668c9441e4f15054a71b066764259aac91f52c51e48ff2656a63c9a09f96e5d","source":"amazon-inspector","versions":["35.7.4"]}]}}
