The fetched bytes are written to /tmp or Windows Temp under disguised names (e.g.,.cache_<hex>, dotnet_diag_<hex>.exe), chmod'd to 0755, and spawned detached via /bin/sh -c or cmd.exe /c start /b. Hostnames and sensitive API names (child_process, chmodSync) are reassembled at runtime from split string arrays to defeat static analysis. The package's stated purpose (finance/tax operations frontend) has no legitimate need to fetch and execute an opaque native binary from non-publisher infrastructure.\n","affected":[{"package":{"ecosystem":"npm","name":"sme-rko-finance-front-operations-tax"},"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":"_platform.js","sha256":"307674aad732cc70bc45e5f93c4845259265b97d5abc258ec2934378a714afa8","tlsh":"eca1b45916fa30180693e5d4851f981a719efa8332c4d898fb8c66948fe652883b39fc"}],"package_integrity":[{"filename":"sme-rko-finance-front-operations-tax-35.8.1.tgz","hashes":{"sha1":"dedde8deb6bc52732edc7fad22c89a4d4dd434d1","sha512_sri":"sha512-P7UJHM7IHMU/v5LgLqNfyl6nLRPEimc6oMiaTK539JHBZyv/EyVwpe0utjvVSlOslnANdejs5Abbj83xC/xmcA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/sme-rko-finance-front-operations-tax/v/35.8.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017166","import_time":"2026-08-08T00:53:08.144365188Z","modified_time":"2026-08-08T00:47:27Z","sha256":"ede42a446ab3685943424af5a5411fb93bf5961c83ccf6ce02b35b8d835c60aa","source":"amazon-inspector","versions":["35.8.1"]}]}}
