The fetched bytes are written to /var/tmp/.cache_\u003crand\u003e on Unix or TEMP/dotnet_diag_\u003crand\u003e.exe on Windows, chmodded 0755, and spawned detached via /bin/sh -c or cmd /c start. child_process is loaded via require(\"child_\" + \"process\") and fs.chmodSync via fs[\"chmod\" + \"Sync\"] to evade static scanners. The package advertises itself as a React UI component library; none of this behavior relates to that purpose. Attacker-controlled binaries with disguised on-disk names (dotnet_diag,.cache_) execute on every require() of the package.\n","modified":"2026-08-05T15:52:57.764075252Z","published":"2026-08-05T15:11:46Z","database_specific":{"malicious-packages-origins":[{"sha256":"6f473b4f8898130c8b57fd3a129bf81a38b449ea8970e58a6e4c486943eb5579","source":"amazon-inspector","versions":["35.5.3"],"id":"IN-MAL-2026-015603","import_time":"2026-08-05T15:19:59.916427839Z","modified_time":"2026-08-05T15:11:46Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-pie/v/35.5.3"}],"affected":[{"package":{"name":"dolyame-ui-pie","ecosystem":"npm","purl":"pkg:npm/dolyame-ui-pie"},"versions":["35.5.3"],"database_specific":{"indicators":{"evidence_files":[{"path":"_support.js","sha256":"3e21fb4b3bfd338961a5c56f81fee1db9d8a2ebea4a08bc5564baeb62aa22fd3","tlsh":"a0a1979a16b670098bb0e7e4c7175416f65bf66333808294fb9c65944fb312883b2dfc"}],"package_integrity":[{"filename":"dolyame-ui-pie-35.5.3.tgz","hashes":{"sha512_sri":"sha512-bO0S0Rnkwld1OGWwztRkFr67XCgDKtXhHbWetRDY4iF8SZ1SzmqDHlNY0tlcdCe5am1PvJwQxzzRBYKXG1p0Dw==","sha1":"7e3c1bb9df175e0246b790067c4020a321b30059"}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-ui-pie/MAL-2026-13173.json","cwes":[{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."}]}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
