Zodiac is a DNS protocol analyzation and exploitation program. It is a robust tool to explore the DNS protocol. Internally it contains advanced DNS routines for DNS packet construction and disassembling and is the optimal tool if you just want to try something out without undergoing the hassle to rewrite DNS packet routines or packet [...]

rtpbreak 1.3a has been released, we initially brought you news of this tool back in August 2007 with the first announcement of rtpbreak.

With rtpbreak you can detect, reconstruct and analyze any RTP session. It doesn’t require the presence of RTCP packets and works independently form the used signaling protocol (SIP, H.323, SCCP etc). The input [...]

CDPSnarf if a network sniffer exclusively written to extract information from CDP packets. It provides all the information a “show cdp neighbors detail” command would return on a Cisco router and even more.
The application is written in C using the popular PCAP library.

Sample Output
Cisco AIR-AP1231G-E-K9 Access Point:

$ sudo ./cdpsnarf eth2
Waiting for a CDP packet…

One of our favourite all time tools for attacking web applications has been updated! Burp Suite has now reached version 1.1! This is a major release - not a minor upgrade.
Burp Suite is an integrated platform for attacking web applications. It contains all of the Burp tools with numerous interfaces between them designed to facilitate [...]

NetworkMiner is a passive network sniffer/packet capturing tool for Windows with an easy to use interface. It can detect operating systems, sessions, hostnames, open ports etc. without putting any traffic on the network. NetworkMiner can also parse PCAP files for off-line analysis.
NetworkMiner makes use of OS fingerprinting databases from both p0f (by Michal Zalewski) and [...]

VoIP Hopper is a GPLv3 licensed security tool, written in C, that rapidly runs a VLAN Hop into the Voice VLAN on specific Ethernet switches. VoIP Hopper does this by mimicking the behavior of an IP Phone, in both Cisco and Avaya IP Phone environments.
In Cisco IP Phone networks, it first dissects either [...]

Unicornscan has always been a favourite of mine, especially for UDP scanning and scanning large networks (and getting it done fast).
Unicornscan is a new information gathering and correlation engine built for and by members of the security research and testing communities. It was designed to provide an engine that is Scalable, Accurate, Flexible, and Efficient. [...]

tcpflow is a program that captures data transmitted as part of TCP connections (flows), and stores the data in a way that is convenient for protocol analysis or debugging. A program like ‘tcpdump’ shows a summary of packets seen on the wire, but usually doesn’t store the data that’s actually being transmitted. In contrast, tcpflow [...]

The LORCON packet injection library provides a high level interface to transmit IEEE 802.11 packets onto a wireless medium. Written for Linux systems, this architecture simplifies the development of 802.11 packet injection through an abstraction layer, making the development of auditing and assessment tools driver- independent.
Using LORCON, developers can write tools that inject packets onto [...]

rtpBreak detects, reconstructs and analyzes any RTP [rfc1889] session through heuristics over the UDP network traffic. It works well with SIP, H.323, SCCP and any other signaling protocol. In particular, it doesn’t require the presence of RTCP packets (voipong needs them) that aren’t always transmitted from the recent VoIP clients.
The RTP sessions are composed by [...]
