The downloaded bytes are written to `/var/tmp/.cache_<hex>` on Unix or `%TEMP%\\dotnet_diag_<hex>.exe` on Windows, chmod 0755, and spawned detached via `spawn(\"/bin/sh\", [\"-c\", fp + \" &\"], {detached:true})` or `cmd /c start /b`. The package advertises a trivial no-op class and ships no native source consistent with the download; the hostnames are unrelated to the declared purpose, there is no version pinning or hash/signature verification, and the destination assembly and DNS-TXT fallback are structured to evade static string scanners. The staging paths use hidden dotfile / diagnostic-lookalike names to blend with normal temp-file activity.\n","affected":[{"package":{"ecosystem":"npm","name":"delivery-ci-codeceptjs"},"versions":["35.1.7"],"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":"_helpers.js","sha256":"2a814a73babd01cf799f66265009c12297c248b4e5d7121b4e2abe7b598f09a6","tlsh":"05a1765a156670198bb0dbf48b175419f65af6a33380c288fb5c65981f7316483f2efc"}],"package_integrity":[{"filename":"delivery-ci-codeceptjs-35.1.7.tgz","hashes":{"sha1":"46df18995fa815219e485ff1e185042d84971d1e","sha512_sri":"sha512-Os81++hgUjYHJbjgpEvOngw+LzJwCmYkVdo9XrLYfF7RmlH9tUfL0CJPUpWu0OQnPI1GoNUwmNu6FNViQyqncA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/delivery-ci-codeceptjs/v/35.1.7"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017049","import_time":"2026-08-07T12:51:23.848009151Z","modified_time":"2026-08-07T12:36:30Z","sha256":"0287654a4d9fa3f7e6f9a35c8bf06a8bb4f18fbbc3a5b3df3450a6c681897b49","source":"amazon-inspector","versions":["35.1.7"]}]}}
