Scapy
A powerful interactive packet manipulation program.
Overview
Scapy is a powerful Python-based interactive packet manipulation program and library. It can forge or decode packets for a wide number of protocols, send them on the wire, capture them, and match requests and replies. It can easily handle most classic tasks like scanning, tracerouting, probing, unit tests, attacks, or network discovery.
✨ Key Features
- Packet forging and crafting for numerous protocols
- Packet sniffing and decoding
- Sending and receiving packets
- Matching requests with replies
- Can be used as a library in Python scripts or as a standalone tool
- Extensible to support new protocols
🎯 Key Differentiators
- Flexibility of being both a standalone tool and a Python library.
- Ability to combine sending, sniffing, and parsing packets in a single framework.
- Vast number of supported protocols.
Unique Value: Offers unparalleled flexibility for crafting and manipulating network packets at a low level, enabling the creation of custom network tools and exploits that are not possible with other off-the-shelf software.
🎯 Use Cases (5)
✅ Best For
- Crafting custom TCP/IP packets to test firewall rules.
- Developing proof-of-concept exploits for network-level vulnerabilities.
- Automating network discovery and fingerprinting tasks.
💡 Check With Vendor
Verify these considerations match your specific requirements:
- High-level application security testing.
- Automated vulnerability scanning.
- Post-exploitation activities.
🏆 Alternatives
While tools like hping3 are powerful for packet generation from the command line, Scapy's integration with Python allows for far more complex logic, automation, and scripting.
