It downloads a platform-specific native binary (/pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe), writes it to /var/tmp/.cache_<hex> or %TEMP%\\dotnet_diag_<hex>.exe under a cover-story filename, chmods 0755, and spawns it detached via /bin/sh or cmd. The runtime-reconstructed destinations, DNS-TXT covert channel, hidden staging paths with diagnostic-tool-lookalike filenames, and mismatch between the declared UI purpose and the fetch-and-execute behavior identify this as a supply-chain dropper rather than legitimate functionality.\n","affected":[{"package":{"ecosystem":"npm","name":"dolyame-ui-notification"},"versions":["35.5.4"],"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":"_compat.js","sha256":"0143f51b2ce4a1229fdd819bac45a76a0dd9eee298d0b9a758920c291cd33bf7","tlsh":"c2a1859a22aa711847b097e486174416f65bf66333c0c6d4fb9ca9945fb212482b2efc"}],"package_integrity":[{"filename":"dolyame-ui-notification-35.5.4.tgz","hashes":{"sha1":"24db3dbdbab67be585d431cd6b443f10bf7306b6","sha512_sri":"sha512-8cV7DxBVlSw4zowgleFJ39Odk0BW/m8zoIGLTWcW+Io0rodlkw1P5zicUfqyksu3cNAwI0JopVICDMR8HTas3w=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-notification/v/35.5.4"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015611","import_time":"2026-08-05T15:20:00.209185001Z","modified_time":"2026-08-05T15:13:00Z","sha256":"27d450fda6c199002bb4eb20b3bf624e31393ae3ed30e9a36fce17507472b962","source":"amazon-inspector","versions":["35.5.4"]}]}}
