Scapy is an open source Python-based interactive packet manipulation and network discovery tool created by Philippe Biondi. It allows users to craft, send, and capture custom packets and analyze their behavior. Additionally, it can generate random packets to test a network's security and resilience, as well as be used to create powerful tools for troubleshooting, testing, and security audits. Scapy also provides a wide range of features for packet manipulation, network discovery, and security testing. It includes a powerful packet crafting engine, allowing users to craft their own packets, as well as capture and analyze data from existing packets. It also includes a powerful packet sniffer, allowing users to capture and analyze packets from their network. Furthermore, it can be used for network discovery, port scanning, and service identification. Additionally, Scapy supports a variety of protocols, including Ethernet, IP, ICMP, TCP, and UDP.
