The fetched bytes are written to /tmp or %TEMP% under names impersonating system diagnostics (.cache_\u003chex\u003e, dotnet_diag_\u003chex\u003e.exe), chmod 0755, and spawned detached via /bin/sh -c or cmd with unref(), yielding remote code execution on the installer host. A state file.analytics_state is used to masquerade as telemetry.\n","modified":"2026-08-05T16:50:06.927435757Z","published":"2026-08-05T15:35:45Z","database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015759","import_time":"2026-08-05T16:13:41.785799728Z","modified_time":"2026-08-05T15:35:45Z","sha256":"a5f53755fd64cd249daeb83c1f148b5f4e600e4f59cc07cfa99fe6579992b0a9","source":"amazon-inspector","versions":["35.9.1"]}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bigops-products-deposits/v/35.9.1"}],"affected":[{"package":{"name":"bigops-products-deposits","ecosystem":"npm","purl":"pkg:npm/bigops-products-deposits"},"versions":["35.9.1"],"database_specific":{"cwes":[{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."}],"indicators":{"package_integrity":[{"filename":"bigops-products-deposits-35.9.1.tgz","hashes":{"sha1":"4b0e545da399268a6a2a6b1a7b0e0424b4c10ec5","sha512_sri":"sha512-30MPGTuAQcDQLJYqjM6kzIgHX6Pvh7v8BVvBF/0VGzc9/ac4FAtqQMK2jubBhFWSDhDm5b0i6/d1mILdsegSTw=="}}],"evidence_files":[{"path":"_runtime.js","sha256":"43339f9591ba0bd81cc1928fa832930f0b911c77d6c0d70bf3ffb66e53a29674","tlsh":"20b1a85605a5701d8bb0d7e087175416f65bf663378092d4faaca9841f7262483b2efc"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/bigops-products-deposits/MAL-2026-13239.json"}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
