DHCP Toolset

Some tools to mess around with DHCP protocol. Useful for Active Directory Attacks or MITM LAN Attacks

• Deploy Rogue DHCP
• Sniff DHCP Discoveries
• MITM with Fake Router/DNS

Keep in mind that you must use other tools to complement MITM attacks with DHCP. For example:

• setting up a custom DNS Server
• configure ip forwarding/traffic inspection when impersonating a gateway
• faulty behaviour due to dhcp's protocol's nature

To Do

• DHCPv6 Support
• Multi-threading
