Scapy: low level packet hacking toolkit for Python
Scapy is a Python module and interactive program for low-level network programming that attempts to make it easier without abstracting away the technical details. This project is fairly prominent in cybersecurity space and used for things like exploit development, data exfiltration, network recon, intrusion detection and analysing captured traffic. Scapy integrates with data visualisation and report generation tooling for presenting the results of your research to bug bounty program or during the meeting with customer or management. The foundational idea for Scapy is proposing a Python-based domain specific language for easy and quick wire format management.
