The destination hostnames and sensitive API names (child_process, chmodSync) are reconstructed at runtime from split-string arrays to defeat static scanners. The downloaded bytes are written to /var/tmp/.cache_<rnd> or TEMP/dotnet_diag_<rnd>.exe, chmod 0755, then spawned detached via /bin/sh or cmd. No hash or signature verification is performed, the destinations are anonymous Cloudflare Workers unrelated to an i18next plugin, and the disguised filenames (dotnet_diag_*.exe,.cache_*) impersonate unrelated system components. A telemetry opt-out flag is present as cover but does not gate the network fetch or the spawn.\n","affected":[{"package":{"ecosystem":"npm","name":"devplatform-spa-plugin-i18next-instance"},"versions":["35.5.9"],"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":"setup.js","sha256":"cb06e4a5652c9f8100340e41c1524dc9675bc5e8966f49f12dc03711bf8b5225","tlsh":"c1a1985a15a5700887b0dbe4cb175416f65bf66333c08684fbaca5995f731248272dfc"}],"package_integrity":[{"filename":"devplatform-spa-plugin-i18next-instance-35.5.9.tgz","hashes":{"sha1":"5890ba30a298829e0d715db417d2e0f1647b48cd","sha512_sri":"sha512-1c+iwkfF/dLeja4EuZkvDeo91Yy2lJbtN4z/ZCFRAw565lwq/Rb/rq1VPnCYZdeLENfGzS01CxSFj68SQ/s8PQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/devplatform-spa-plugin-i18next-instance/v/35.5.9"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015001","import_time":"2026-08-05T14:19:51.343384235Z","modified_time":"2026-08-05T13:41:47Z","sha256":"0a8078abf02317c9e0c0255c48434f68798e80d2282d46acb8a8643e0cdb18c8","source":"amazon-inspector","versions":["35.5.9"]}]}}
