ARP Shenanigans - Crash in /root/background.py - SPOILERS #34

Open ryohare opened 3 years ago

ryohare commented 3 years ago

Crash in /root/background.py when the DNS Response record is type "CNAME" rather than "A".

Crash mangles terminal output but able to sift through and see its an uncaught exception exception during a regex looking for an IP address.

Causes session to be broken - ARP spoofing works but no request for the DNS record comes in after crash. This requires a new instance of the "terminal" to be used.
