Scapy

It can easily handle most classical tasks like scanning, tracerouting, probing, unit tests, attacks or network discovery (it can replace hping , 85% of nmap , arpspoof , arp-sk , arping , tcpdump , wireshark , p0f , etc.). It also performs very well at a lot of other specific tasks that most other tools can't handle, like sending invalid frames, injecting your own 802.11 frames, combining techniques (VLAN hopping+ARP cache poisoning, VoIP decoding on WEP protected channel, ...), etc. Scapy supports Python 3.7+. It's intended to be cross platform, and runs on many different platforms (Linux, OSX, BSD, and Windows). Scapy can easily be used as an interactive shell to interact with the network. The following example shows how to send an ICMP Echo Request message to github.com , then display the reply source IP address: Scapy works without any external Python modules on Linux and BSD like operating systems. On Windows, you need to install some mandatory dependencies as described in the documentation. To benefit from all Scapy features, such as plotting, you might want to install Python modules, such as matplotlib or cryptography . See the documentation and follow the instructions to install them.
