Provide examples of shellcode generation

[brucebatman]

Thanks for the tool, would it be possible to provide examples of shell-code generation, i have been trying multiple approaches, but no dice in getting shellcode execution, i have tried simple msgbox, and other more complex with CS and MSF.

Here are my steps i have used.

• Payloads tested (metasploit, x64 reverse_shell_tcp, x86_reverse_shell_tcp, msgbox, adduser) everything generated in C format
• Tested with Cobalt Strike 4.8, C staged and stageless shellcodes
• go version go1.21.0 linux/amd64
• go run 3DESEncryptor.go, and then enter the values in the main.go at the specific places for IV, SC, KEY
• no specific sandboxing processes are running that could break the execution flow
• Compile "env GOOS=windows GOARCH=amd64 go build -x -trimpath -o ./main.exe main.go"
• No connectivity issue, it can reach internet or the local network.
• Execute on the victim machine, no reverse shell or no pop-ups.
• Machines are Windows 10 Updated, administrative access, 8gb of ram 4 cpu, 128gb of hard drive.

Again thanks for your help

Tested with Cobalt Strike 4.8, C stageless shellcodes with your example , dont Execute on the test local machine not work.

Why you add -x -trimpath GOOS=windows GOARCH=amd64 go build -o a.exe main.go same , not work
