The terms ARP Spoofing and ARP Poisoning are generally used interchangeably. This results in the linking of an attacker’s MAC address with the IP address of a legitimate computer or server on the network. How does ARP spoofing work?ĪRP spoofing is a type of attack in which a malicious actor sends falsified ARP (Address Resolution Protocol) messages over a local area network.

It runs on various Unix-like operating systems including Linux, Mac OS X, BSD and Solaris, and on Microsoft Windows.Įttercap-graphical Ettercap supports active and passive dissection of many protocols (even encrypted ones) and includes many feature for network and host analysis. It can be used for computer network protocol analysis and security auditing. Ettercap was born as a sniffer for switched LAN (and obviously even “hubbed” ones), but during the development process it has gained more and more features that have changed it to a powerful and flexible tool for man-in-the-middle attacks.Įttercap is a free and open source network security tool for man-in-the-middle attacks on a LAN.
