TCPDump - Network Packet Analyzer

TCPDump, a powerful command-line packet analyzer; and libpcap, a portable C/C++ library for network traffic capture. It prints out a description of the contents of packets on a network interface that match the boolean expression. The Packet Capture library provides a high level interface to packet capture systems. All packets on the network, even those destined for other hosts, are accessible through this mechanism.

Wireshark - Network Traffic Analyzer

Wireshark is a network traffic analyzer, or "sniffer", for Linux, macOS, *BSD and other Unix and Unix-like operating systems and for Windows. It uses Qt, a graphical user interface library, and libpcap and npcap as packet capture and filtering libraries.

esp_wifi_repeater - A full functional WiFi Repeater (correctly: a WiFi NAT Router)

This is an implementation of a WiFi NAT router on the esp8266 and esp8285. It also includes support for a packet filtering firewall with ACLs, port mapping, traffic shaping, hooks for remote monitoring (or packet sniffing), an MQTT management interface, and power management. For a setup with multiple routers in a mesh to cover a larger area a new mode "Automesh" has been included https://github.com/martin-ger/esp_wifi_repeater#automesh-mode . NEW feature: OTA update support - see https://github.com/martin-ger/esp_wifi_repeater#ota-over-the-air-update-support .

BruteShark - Network Analysis Tool

CSharp

BruteShark is a Network Forensic Analysis Tool (NFAT) that performs deep processing and inspection of network traffic (mainly PCAP files, but it also capable of directly live capturing from a network interface). It includes: password extracting, building a network map, reconstruct TCP sessions, extract hashes of encrypted passwords and even convert them to a Hashcat format in order to perform an offline Brute Force attack. The main goal of the project is to provide solution to security researchers and network administrators with the task of network traffic analysis while they try to identify weaknesses that can be used by a potential attacker to gain access to critical points on the network.

htracr - HTTP sniffing and low-level visualisation

Javascript

htracr is a packet sniffer and visualisation tool for HTTP. It does not give you a score, grade, or hold your hand when you're crying because your site is so damn slow, but it will give you unparalleled insight into what's actually happening on the wire between your browser and the Web. First you'll need Node and its package manager, npm. You'll also need a modern Web browser (known to work: Safari 5, FireFox 4, and Chrome).

ChameleonMini - The ChameleonMini is a versatile contactless smartcard emulator compliant to NFC

This is the official repository of ChameleonMini, a freely programmable, portable tool for NFC security analysis that can emulate and clone contactless cards, read RFID tags and sniff/log RF data. Thanks to over 1700 backers from our Kickstarter project, the current Revision G has been realized by Kasper & Oswald GmbH. We are aware of various third-party ChameleonMini clones or modified variants that are available on the Internet. Warning: We have evidence that some of these devices are defective or suffer from reading problems et cetera. Please understand that we cannot give support for these non-official devices, as we have no schematics / layout or other information, nor do we know the manufacturers. In case of problems, please contact the manufacturers of your device directly.

netsniff-ng - The packet sniffing beast

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.

sniffer - Log and Analyze Outgoing HTTP Requests

Ruby

You can configure capacity of storage to prevent the huge memory usage and set up log rotation. By default log rotation is active (when capacity is set) and log works like a queue. If rotation is disabled - requests will be logged until result log size reaches the capacity.

stream-interceptor - Intercept, modify and/or ignore chunks data and events in any readable stream

Javascript

Tiny node.js module to intercept, modify and/or ignore chunks of data and events in any readable compatible stream before it's processed by other stream consumers (e.g: via pipe()).It becomes particularly useful to deal with net/http/fs streams.

node-license-sniffer - Detect the license of node.js projects and their dependencies

Javascript

node-license-sniffer is a tool for detecting the license of node packages. It will attempt to read the license from package.json. If it cannot find the license in package.json, it will read LICENSE and similarly named files and attempt to guess the license in use.
