Malicious code in checkout-desktop-total (npm)

Host literals are split into arrays and joined at runtime to evade grep-based scanning. The downloaded bytes are written to a disguised path — '.cache_<rand>' under /tmp on Unix, 'dotnet_diag_<rand>.exe' under %TEMP% on Windows — chmodded 0755, and spawned detached via /bin/sh -c or cmd.exe /c start /b with windowsHide:true. An on-disk marker '.analytics_state' is written. The package name and its deceptive filenames impersonate benign tooling; there is no legitimate reason for a 'checkout-desktop-total' library entry to fetch and execute an opaque binary from a Cloudflare Workers host on import.
