Scapy
Scapy is a Python-based interactive packet manipulation program
Scapy is a powerful Python-based interactive packet manipulation program and library. It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, store or read them using pcap files, match requests and replies, and much more. It is designed to allow fast packet prototyping by using default values that work. 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 2.7 and Python 3 (3.4 to 3.7). It's intended to be cross platform, and runs on many different platforms (Linux, OSX, *BSD, and Window -

netsniff-ng
A Swiss army knife for your daily Linux network plumbing
netsniff-ng is a free Linux networking toolkit, a Swiss army knife for your daily Linux network plumbing if you will. Its gain of performance is reached by zero-copy mechanisms, so that on packet reception and transmission the kernel does not need to copy packets from kernel space to user space and vice versa. Our toolkit can be used for network development and analysis, debugging, auditing, or network reconnaissance. -

xdp
Package xdp allows one to use XDP sockets
Package github /asavie/xdp allows one to use XDP sockets from the Go programming language. With the default UDP payload size of 1400 bytes, running on Linux kernel 5.1.20, on a tg3 (so no native XDP support) gigabit NIC, sendudp does around 980 Mb/s, so practically line rate. TL;DR: in the same environment, sending a pre-generated DNS query using an ordinary UDP socket yield around 30 MiB/s whereas sending it using the senddnsqueries example program yields around 77 MiB/s. Connecting a PC with Intel Core i7-7700 CPU running Linux kernel 5.0.17 and igb driver to a laptop with Intel Core i7-5600U CPU running Linux kernel 5.0.9 with e1000e with a cat 5E gigabit ethernet cable. -

PacketStreamer
Distributed tcpdump for cloud native environments
Deepfence PacketStreamer is a high-performance remote packet capture and collection tool. It is used by Deepfence's ThreatStryker security observability platform to gather network traffic on demand from cloud workloads for forensic analysis. PacketStreamer sensors are started on the target servers. Sensors capture traffic, apply filters, and then stream the traffic to a central receiver. Traffic streams may be compressed and/or encrypted using TLS. The PacketStreamer receiver accepts PacketStreamer streams from multiple remote sensors and writes the packets to a local pcap capture file. PacketStreamer sensors collect raw network packets on remote hosts. It selects packets to capture using a BPF filter, and forwards them to a central receiver process where they are written in pcap format. Sensors are very lightweight and impose little performance impact on the remote hosts. PacketStreamer sensors can be run on bare-metal servers, on Docker hosts, and on Kubernetes nodes. -

Shadow Network Fingerprinting Engine
SNF is a 100% offline, air-gap passive network intelligence engine
# SNF — Shadow Network Fingerprinting Engine 100% offline. Air-gap-native. Written entirely in Rust. SNF captures raw packets, reconstructs TCP/UDP flows, and runs them through 14 deterministic protocol analyzers. It detects C2 beacons, DGA domains, DNS tunnels, lateral movement, data exfiltration, and full ICS/SCADA protocol abuse across Modbus, S7comm, EtherNet/IP, PROFINET, and DNP3. Every run produces structured NDJSON with a determinism guarantee — same PCAP, same config, same version, SHA-256 identical output every time. Court-admissible evidence bundles built in. **Zero network calls. Ever. Not a setting. Architecture.** ## Validated Results - Emotet epoch 3 PCAP — 23 IOC hits, 52 threat matches - MAWI backbone — 14.9M packets, zero crashes, 332K graph nodes - nmap standard scan — 1,971 scan events detected ## Links - Website: https://shadownf.com - GitHub (open core): https://github.com/padigeltejas/snf-core -

Sniffer4J
A java packet sniffer and forger that wraps pcap libs.
Sniffer4J is a java packet capture and manipulation tool that allows full analysis of a network. It is built upon pcap libs (winpcap, and libpcap) and can run in Windows and most Linux flavors. The current stable version (2.0) provides shared libraries (.dll and .SO) compiled and tested for both x86 and x64 architectures. Sniffer4J work’s by parsing packets in a comprehensive Pdu format. Each Pdu encapsulates the next one, making easy to navigate through the Frame. Frames can be forged in the same manner allowing them to be injected in the network. Sniffer4J support several protocols including: * Ethernet I & II (including LLC and SNAP frames) * Vlan (802.1Q) * Arp * Ipv4, Ipv6, (including options) * Next Header for IpV6 * Ipsec * TCP (including options) * Udp * Icmp (including RFC 2461 and Ipv6) * Lldp * Ipx And more to come… Remember: If you don’t test your network, some else will… Bernardo
