Cain & Abel is a password recovery tool for Microsoft Operating Systems. It allows easy recovery of various kind of passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP conversations, decoding scrambled passwords, revealing password boxes, uncovering cached passwords and analyzing routing protocols. The program does not exploit any software vulnerabilities or bugs that could not be fixed with little effort. It covers some security aspects/weakness present in protocol's standards, authentication methods and caching mechanisms; its main purpose is the simplified recovery of passwords and credentials from various sources, however it also ships some "non standard" utilities for Microsoft Windows users.

Cain & Abel has been developed in the hope that it will be useful for network administrators, teachers, security consultants/professionals, forensic staff, security software vendors, professional penetration tester and everyone else that plans to use it for ethical reasons. The author will not help or support any illegal activity done with this program. Be warned that there is the possibility that you will cause damages and/or loss of data using this software and that in no events shall the author be liable for such damages or loss of data. Please carefully read the License Agreement included in the program before using it.

The latest version is faster and contains a lot of new features like APR (Arp Poison Routing) which enables sniffing on switched LANs and Man-in-the-Middle attacks. The sniffer in this version can also analyze encrypted protocols such as SSH-1 and HTTPS, and contains filters to capture credentials from a wide range of authentication mechanisms. The new version also ships routing protocols authentication monitors and routes extractors, dictionary and brute-force crackers for all common hashing algorithms and for several specific authentications, password/hash calculators, cryptanalysis attacks, password decoders and some not so common utilities related to network and system security.

Yahoo Messenger Monitor Sniffer is handy network utility software designed to capture and observe Yahoo Messenger conversations on all computers in a network. It is able to record conversations automatically in real time. And export all intercepted messages to HTML files for later processing and analyzing. It is very easy to make it to work, and it will monitor all conversations in your Local Area network without the use of client software installed on the remote computer.

Sniff - O - Matic is a network protocol analyzer and packet sniffer with a clear and intuitive interface. It captures network traffic and enables you to analyze the data. Detailed packet information is available in a tree structure or a raw data view of the packet data.

We believe most sniffers are too complex. Too many features, too many buttons, too much to learn. Sniff - O - Matic solves all of this. Rather than implementing obscure protocols no one actually uses, we have added the most common protocols to provide you a useful tool at a reduced price. We do not use driver software, or worse, third party drivers you have no control of to capture packets.
