Welcome back to my second post for the SLAE certification.
Today we are going to build a reverse_shell shellcode and again you can find the files here.
This task is very similar to the first one, so i dont have to look up new/more information. Lets switch some syscalls and registers!
The code for socket_setup, fileDescriptors and shellExecution are the same as in our bind_shell assignment.
After the socket_setup we connect to a specific port and ip, which are also marked in the code with comments:
So lets try our new shellcode:
#1 nc -lv 11013
#2 ./reverse_shell
#3 Boom!
Now we are able to own systems behind NAT with our selfwritten shellcode, nice!
