Inject data into an already opened TCP connection.
NetInject uses ptrace library to inject data into one of the process' network sockets. It works by live editing the process memory and add instructions to write in file descriptors corresponding to TCP sockets.
(Not sure if it's the fastest way, if you have a better way to do that, I'd like to know it)
run :
./netinject PID_TO_ATTACH_TO
A list of file descriptors appears :
FD TYPE STATE IP
4 TCP 1 192.168.0.16:9090 ->192.168.0.16:36254
Choice:
4
Choose one of the list and the prompt will let you choose data you want to inject.
Works for 32 and 64 bits architectures, edit Makefile to adjust :
Leave original content for 32 bits :
gcc -o netinject netinject.o design.o
Add -DX64 for 64 bits support :
gcc -DX64 -o netinject netinject.o design.o
