Destination hostnames and the child_process module name are assembled at runtime from split-string arrays to evade static scanners. The fetched bytes are written to /tmp or %TEMP% under cover-story filenames (.cache_<rand>, dotnet_diag_<rand>.exe), chmodded to 0755, and spawned detached via /bin/sh -c '<path> &' or cmd. lib/telemetry.js contains a duplicate write-chmod-spawn path decoded from base64 buffers, ensuring execution if _polyfill.js is removed. The package presents itself as a UI/data-QA utility; the loader-dropper behavior does not match that stated purpose.\n","affected":[{"package":{"ecosystem":"npm","name":"dolyame-ui-dataqa"},"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":"f1a4545973fac0bd382811cfa3e0dfe923f9a908ddbfce4816904ab94eb19bad","tlsh":"dba1c75a16fb70180693e5d4852f5816b29bfa5332d4e8c4fb4ca6944fd627883b38ec"},{"path":"lib/telemetry.js","sha256":"e722caf302f0204a20842ca68bc767f5893f56a1ace89948150ed67f702c319d","tlsh":"3b73304966fb10214263b0685fbb40437635c4072a4aed5dba9c43ec9f8db3896f1fb9"}],"package_integrity":[{"filename":"dolyame-ui-dataqa-35.8.1.tgz","hashes":{"sha1":"5f2ace63f674e319709ae84ce887eb51f08143b2","sha512_sri":"sha512-PamDOHXerFgzd9Ds4Dua5lm117Jx7H0/9zoIBUkUGVciP9N0HrYtn2hE5k5Xx2GVYUS7FPqkxRNk3HM/4ebz1Q=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-dataqa/v/35.8.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-016996","import_time":"2026-08-07T12:51:21.446381682Z","modified_time":"2026-08-07T12:28:35Z","sha256":"1c924fc6297738267a66dffbb2d06dcca26e888b5c3abd1f10b20c22faa3e3b7","source":"amazon-inspector","versions":["35.8.1"]}]}}
