Active ARP protects your PC against Man-In-The-Middle (MITM) attacks. This is a script written in C to provide protection against malicious ARP attacks, which changes the gateway's MAC Address in the ARP table of a victim's PC.
Active ARP needs arptables and libpcap-dev to run, so just install them:
sudo apt-get install arptables libpcap-dev
There's a pre-built executable in the builds folder, or build it yourself:
To build:
- Run
compile_arppd_linux
OR
- Go in the main directory
- Run:
gcc -o builds/defender-win64 src-win64/defender.c -lpcap -pthread
When the Active ARP will detect a malicious ARP Packet, it will look like this:
