--- _-= Per source details.

The retrieved payload is written to /var/tmp or %TEMP% under disguised names (.cache_<rnd>, dotnet_diag_<rnd>.exe), chmodded 0755, and spawned detached via /bin/sh -c or cmd.exe. No hash or signature verification is performed, hostnames are unrelated to any declared publisher, and the destinations are concealed via string-split obfuscation. Package name mimics a checkout/payments library, consistent with typosquat lure targeting mobile checkout tooling.
