Cain & Abel

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, recovering wireless network
keys, 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 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
