If you have already achieved MiTM, then you can attempt to steal credentials by stripping the HTTPS off sites. When the victim tries to connect, you establish an HTTPS connection to the site while passing unencrypted HTTP to the victim.
This is mitigated by HSTS.
You can use a WiFi Pineapple to pretend to be a wifi access point. If clients connect to it, then you can MiTM sites.
The ARP protocol is insecure and you can get MITM by ARP spoofing to indicate that the IP of a machine has the MAC of our device.
mitm6 is a tool that exploits the default configuration of Windows to take over the default DNS server. It does this by replying to DHCPv6 messages, providing the victim a IPv6 address and setting the attacker as default DNS server.
For a full explanation of the attack, see the. Mitm6 is designed to work together with for WPAD spoofing and credential relaying.
Many browsers use Web Proxy Auto-Discovery (WPAD) to load proxy settings from the network. A WPAD server provides client proxy settings via a particular URL (e.g., http://wpad.example.org/wpad.dat) upon being identified through any of the following:
DHCP using code 252 entry
DNS, searching for the wpad hostname in the local domain
Microsoft LLMNR and NBT-NS (in the event of DNS lookup failure)
You can use Responder to:
Get MITM
Steal (and potentially downgrade from v2 to v1 beforehand) the NTLM Hash
Mitigation: disable “auto detect proxy” in browser.
