Google Hacks project is a compilation of carefully crafted Google searches that expose novel functionality from Googles search and map services.

For example, you can use it to view a timeline of your search results, view a map, search for music, search for books, and perform many other specific kinds of searches.

Leptons Crack is a generic password cracker, easily customizable with a simple plug-in system. COPYRIGHT=1]
For the incremental scan, the user can provide a regex-like expression
that will be enumerated, thus checking every possible combination. This
powerful feature effectively combines `shoulder-surfing with standard
brute-forcing.

By default it comes with the following modules:
md4 : standard MD4 hash
md5 : standard MD5 hash
nt4 : NT MD4/Unicode
dom : Lotus Domino HTTP password
sha1 : standard SHA-1 hash
null : trivial 1-byte hash
(sample for plug-in developers
Enhancements:
- Added support for any ASCII character (ie. also non-printable) in the charset and regex definition, via (octal), x(hex), (decimal)

Aircrack-ng is a set of tools for auditing wireless networks.
- airodump: 802.11 packet capture program
- aireplay: 802.11 packet injection program
- aircrack: static WEP and WPA-PSK key cracker
- airdecap: decrypts WEP/WPA capture files
Aircrack-ng is the next generation of aircrack with lots of new features.
How do I crack a static WEP key ?
The basic idea is to capture as much encrypted traffic as possible using airodump. Each WEP data packet has an associated 3-byte Initialization Vector (IV): after a sufficient number of data packets have been collected, run aircrack on the resulting capture file. aircrack will then perform a set of statistical attacks developped by a talented hacker named KoreK.
How do I know my WEP key is correct ?
There are two authentication modes for WEP:
Open-System Authentication: this is the default mode. All clients are accepted by the AP, and the key is never checked: association is always granted. However if your key is incorrect you wont be able to receive or send packets (because decryption will fail), so DHCP, ping etc. will timeout.
Shared-Key Authentication: the client has to encrypt a challenge before association is granted by the AP. This mode is flawed and leads to keystream recovery, so its never enabled by default.
In summary, just because you seem to have successfully connected to the access point doesnt mean your WEP key is correct ! To check your WEP key, try to decrypt a capture file with the airdecap program.
How many IVs are required to crack WEP ?
WEP cracking is not an exact science. The number of required IVs depends on the WEP key length, and it also depends on your luck. Usually, 40-bit WEP can be cracked with 300.000 IVs, and 104-bit WEP can be cracked with 1.000.000 IVs; if youre out of luck you may need two million IVs, or more.
Theres no way to know the WEP key length: this information is kept hidden and never announced, either in management or data packets; as a consequence, airodump can not report the WEP key length. Thus, it is recommended to run aircrack twice: when you have 250.000 IVs, start aircrack with "-n 64" to crack 40-bit WEP. Then if the key isnt found, restart aircrack (without the -n option) to crack 104-bit WEP.
Enhancements:
- This release adds an ACX injection patch, and updates the rtl8187 patch for 2.6.21.
- It fixes madwifi-ng detection with airmon-ng.
- It fixes 2 bugs in aircrack-ng related to WPA cracking.
- It fixes an old Debian bug (#417388).
- It fixes the use of wlanng, and fixes IP address writing in the CSV file with airodump-ng.
- It fixes a bug in the GUI for Windows and adds a PTW option.

Ophcrack is a Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method.
The project comes with a GTK+ Graphical User Interface and runs on Windows, Mac OS X (Intel CPU) as well as on Linux.
Main features:
- Runs on Windows, Linux and Mac OS X (intel).
- Cracks LM and NTLM hashes.
- Free tables available for alphanumeric LM hashes.
- Loads hashes from local SAM, remote SAM.
- Loads hashes from encrypted SAM recovered from a Windows partition.
The ophcrack LiveCD contains a full linux system (SLAX), ophcrack for linux and rainbow tables for alphanumerical passwords.
The liveCD cracks passwords automatically, no installation necessary, no admin passwort necessary (as long as you can boot from cd).
Enhancements:
- Vista support with the latest version of ophcrack (2.3.4)
- Easier to changes tables

goblinhackis a rogue-like game with ASCII graphics, OpenGL, and smooth scrolling.
Goblins hoard in their foul, dark hole, Plotting and digging and hating all things, Theyll gnash on your bones and eat you whole, And deliver your soul to the Goblin King.
Enhancements:
- This release adds animated black, white, and amethyst dragons, jelly molds, evil blobs, knee gnashers, fractal lakes, fate points, acid weapons, fire/cold/acid proof armour, and many bugfixes.

crackblock is a daemon that monitors your /var/log/secure for brute-force password crack attempts and ssh login failures.

The rpm should install on any rpm based system and requires iptables, tail, PERL, and PERLs syslog features. All of which are probably already installed on your system.
