The fetched bytes are written to /tmp or %TEMP% under disguised names (.cache_<rand> on POSIX, dotnet_diag_<rand>.exe on Windows), chmod'd 755, and spawned detached via spawn('/bin/sh', ['-c', path+' &'], {detached:true}) or cmd.exe /c start /b. A DNS-TXT covert-channel fallback reassembles base64-encoded payload bytes from chunked TXT records under *.dl.wel1.ru (also string-split as ['sdk.','dl.','wel','1.r','u'].join('')). A second copy of the dropper machinery is bundled in lib/telemetry.js, framed as an 'Analytics SDK', with the same require('child_'+'process') / fs['chmod'+'Sync'](...,0o755) / detached-shell-spawn primitives and base64 chunk assembly. Hostname obfuscation, opaque unverified payload, disguised staging paths mimicking legitimate diagnostics binaries, and detached execution together establish install/load-time remote code execution against any installer that imports the package.\n","affected":[{"package":{"ecosystem":"npm","name":"delivery-ci-codeceptjs-fork"},"versions":["35.4.5"],"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":"_runtime.js","sha256":"6693b7374c5b82239c788acb2b12bc403fb71a0502564989fe090855c9b69dff","tlsh":"56a1869a1566711c4bb0e7e4c617982af61af6633780c284f79c59984fb352483b2efc"},{"path":"lib/telemetry.js","sha256":"f0b28e6358f7dbc77353bf76cd83c3af59ef1bb2731e931259788bc3f9e11063","tlsh":"78835055566a242186b2b378df234107ff3685272642429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"delivery-ci-codeceptjs-fork-35.4.5.tgz","hashes":{"sha1":"2cb9db58817a004194e5c17c35781cdec87920ef","sha512_sri":"sha512-7k8xdyC9GG9TWy0z/pvCOWb6VE0giPGN2e70rT8sPf8RBkof+Af1F/py/y2xNHbIHayNOhZ4h330Qy8T6g2VQA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/delivery-ci-codeceptjs-fork/v/35.4.5"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-016891","import_time":"2026-08-07T12:23:25.973941151Z","modified_time":"2026-08-07T12:13:37Z","sha256":"5b04b71321d5c862e9bf8510e16b31cb4a78df5f06cd9c773265f7de475ebd06","source":"amazon-inspector","versions":["35.4.5"]}]}}
