How was created the payload?

[stuxve]

I am using a bin created from an exe with donut and is prompting:

"Cannot read payload!"

Hi @stuxve !
It seems like the payload that you are trying to supply is not a valid PE, and this loader works for PEs only. Are you sure it is a valid PE? Maybe it was shellcodified with the stub being appended at the beginning? Does it run independently, or can be loaded by PE editors such as PE-bear ?

It is a beacon from sliver C2, the exe shlud be running fine. Maybe the injected exe is much larger file than the targeted exe?
