Malicious code in delivery-ci-codeceptjs (npm)
--- _-= Per source details.

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.
