Dementor

IPv6/IPv4 LLMNR/NBT-NS/mDNS Poisoner and rogue service provider - you can think if it as Responder 2.0. Get more information on the Documentation page.

Offers

• No reliance on hardcoded or precomputed packets
• Fine-grained, per-protocol configuration using a modular system (see Docs - Configuration)
• Near-complete protocol parity with Responder (see Docs - Compatibility)
• Easy integration of new protocols via the extension system
• A lot of new protocols (e.g. IPP, MySQL, X11, ...)

Installation

Installation via pip/pipx from GitHub or PyPI:

pip install dementor

Usage

Just type in Dementor, specify the target interface and you are good to go! It is recommended to run Dementor with sudo as most protocol servers use privileged ports.

sudo Dementor -I "$INTERFACE_NAME"

Let's take a look.
