Destination hostnames are reassembled from split-string arrays (e.g. [\"oob-worker.cf103-070.wo\",\"rke\",\"rs.de\",\"v\"].join(\"\")) to defeat static inspection, and the dropped file is named to masquerade as a.NET diagnostics artifact (dotnet_diag_) or a hidden cache file (.analytics_state /.cache_). The package's advertised purpose is API client wrappers; fetching and executing arbitrary attacker-controlled binaries is unrelated to that purpose and gives the publisher arbitrary code execution on any machine that installs or imports the package.\n","affected":[{"package":{"ecosystem":"npm","name":"dolyame-ui-eventoutside"},"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":"_bootstrap.js","sha256":"b7cfe4b6ef60a90e8b630b6a6f520a1cbd4c61768e6ea3a3daa6353eac5a9f79","tlsh":"d8a1935a17fa30180392a5d8851f5816719ef65333c4e8d4fb4c66988fab229c3b39fc"}],"package_integrity":[{"filename":"dolyame-ui-eventoutside-35.8.1.tgz","hashes":{"sha1":"0d18b150771881269372326cf05ae06e3e3db511","sha512_sri":"sha512-HJlTLuKCsB1ZfIsSluy4jpJu6n1YJ+Y/UvOdi9argVFGjLORhN9QK8CG5xWddD36AsvFvQEVasmPQUc9CruKOA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-eventoutside/v/35.8.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-016994","import_time":"2026-08-07T12:51:21.377622234Z","modified_time":"2026-08-07T12:28:18Z","sha256":"0d57db31d52ade4e7de9ebb32a078ab75bf12fb7d40cdfb0caf987e5ef62229a","source":"amazon-inspector","versions":["35.8.1"]}]}}
