udp reverse shells

udp-reverse-shell

UDP reverse shells for *nix systems.

I could not find an example anywhere online for a UDP reverse shell in C so I wrote several of them.

Shells included

• Shell over IPv4 and UDP (udp_shell.c).
  • To test it, run first: nc -nlvup 9999
• Shell over IPv6 and UDP: (udp_shell6.c).
  • To test it, run first: ncat -nluvp 9999
• Shell and listener over IPv4, UDP and DTLS:
  • Shell: dtls_shell.c
  • Listener: dtls_server.c
  • To test them, run the listener first and then the reverse shell.
