C2 hostnames and sensitive API names (child_process, chmodSync) are assembled at runtime from split-string arrays joined with '' to defeat static analysis. A second copy of the same fetch → base64 → chmod 0755 → detached-spawn chain, with identical string-concatenation obfuscation of 'child_process', is bundled in lib/telemetry.js as a parallel dropper. Any installer that requires this package executes attacker-controlled binaries with the user's privileges.\n","affected":[{"package":{"name":"dolyame-ui-react-dom-wrapper","ecosystem":"npm","purl":"pkg:npm/dolyame-ui-react-dom-wrapper"},"versions":["35.8.9"],"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":"_helpers.js","sha256":"9fb0e81388448fd8a460b9087fd355fecf9cf5e852135c72ce3a932d91f9552a","tlsh":"34a1b65a16a670188bb09be5c7174416f65bf6633380c298f79ca5985f7312483b2efc"},{"path":"lib/telemetry.js","sha256":"30aea8a1ff1054faca74bb638235d1e035934041e0499c9763b3c54e6e471365","tlsh":"a1835055566a242186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"dolyame-ui-react-dom-wrapper-35.8.9.tgz","hashes":{"sha1":"1ca8e20b3be47109caf746bf38ada25471de27ec","sha512_sri":"sha512-iP7q2xwzG06LAtD/qUQYgkT2JtDhF9Yvk481cP26SaHpMAp8zy2hIMbNJxFrAAaCM/Pe2LWec5H6kHUKK1FzXQ=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-ui-react-dom-wrapper/MAL-2026-13178.json"}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-react-dom-wrapper/v/35.8.9"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015595","import_time":"2026-08-05T15:19:59.648300163Z","modified_time":"2026-08-05T15:10:26Z","sha256":"3c3f53ba29324123e792649baa012f91a2a980590dea560599490d8020b6274b","source":"amazon-inspector","versions":["35.8.9"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
