The downloaded bytes are written to a hidden masquerading path in /tmp or %TEMP% (\".cache_<hex>\" or \"dotnet_diag_<hex>.exe\"), chmod 0755, and spawned detached via /bin/sh -c or cmd.exe. Execution is gated by a TTL stamp file and labelled as telemetry. The hostname obfuscation and DNS-TXT fallback channel are consistent with intentional evasion of static string scanning.\n","affected":[{"package":{"ecosystem":"npm","name":"delivery-ci-jira-rnd"},"versions":["35.5.4"],"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":"_bridge.js","sha256":"fa9d08ce5f5dc12637fb1d2476f05f3be982d4caeb41f0e8b27fb07664ef9237","tlsh":"8ba1969a16a970084bb0a7e48717441af55bf2633781d298fb5c65d41fb24248372efc"}],"package_integrity":[{"filename":"delivery-ci-jira-rnd-35.5.4.tgz","hashes":{"sha1":"6e67592961269c92ce45dd6b7c089beb545de135","sha512_sri":"sha512-SqLsX89HOktpUfy2JmL/HyoIPTX2zVmeAeiSexO/SbM07QE9OtFbk0lywa1QBQ30HLreRPN9IfYcn5gadRSmmQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/delivery-ci-jira-rnd/v/35.5.4"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-016888","import_time":"2026-08-07T12:23:25.836583125Z","modified_time":"2026-08-07T12:13:10Z","sha256":"9178cec9a952384e307589c3d50840761b3c260ced53213ec8a02f85f629bfd9","source":"amazon-inspector","versions":["35.5.4"]}]}}
