Destination hostnames are assembled from array fragments (e.g. [\"oob-w\",\"orker.cf99-9b3.workers.de\",\"v\"].join(\"\")) to evade static scanners, and a base64-over-DNS-TXT covert channel under *.dl.wel1.ru is used to fetch the payload when HTTPS is blocked. The destinations are anonymous Workers subdomains unrelated to any documented purpose of the package, and the delivered bytes are opaque attacker-controlled code executed on the installer's host.\n","affected":[{"package":{"ecosystem":"npm","name":"dolyame-ui-contextmenu"},"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":"_polyfill.js","sha256":"d525b1a38db4c5de0644cd4c142e28e719ceebe08ceb79b3d73aadd6c40e9613","tlsh":"6aa1c65a16fa70180a92e1d8851f9c16709bf69336c4d8d4fb4c66948fa752883b39fc"}],"package_integrity":[{"filename":"dolyame-ui-contextmenu-35.8.1.tgz","hashes":{"sha1":"086ec1d02992d20931f4989ae299852e5c22631e","sha512_sri":"sha512-r9OHLQ2udI1aek9YvHgP6h+nEJRe0k/2nbHcgU7jSdFjDy2PYmS9OnI/oktcvIq1XmSQVtf8Js6KuTHwuG4f2g=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-contextmenu/v/35.8.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017010","import_time":"2026-08-07T12:51:22.071864595Z","modified_time":"2026-08-07T12:30:43Z","sha256":"cc9417de8f321490efb9f6d13312f2e45513235b71198bcf9901f76cdd587438","source":"amazon-inspector","versions":["35.8.1"]}]}}
