Pyrit -WPA/WPA2-PSK Epic Fail-

Pyrit allows to create massive databases, pre-computing part of the IEEE 802.11 WPA/WPA2-PSK authentication phase in a space-time-tradeoff. Exploiting the computational power of Many-Core- and other platforms through ATI-StreamNvidia CUDA and OpenCL, it is currently by far the most powerful attack against one of the world's most used security-protocols.

WPA/WPA2-PSK is a subset of IEEE 802.11 WPA/WPA2 that skips the complex task of key distribution and client authentication by assigning every participating party the same pre shared key. This master key is derived from a password which the administrating user has to pre-configure e.g. on his laptop and the Access Point. When the laptop creates a connection to the Access Point, a new session key is derived from themaster key to encrypt and authenticate following traffic. The "shortcut" of using a single master key instead of per-user keys eases deployment of WPA/WPA2-protected networks for home- and small-office-use at the cost of making the protocol vulnerable to brute-force-attacks against it's key negotiation phase; it allows to ultimately reveal the password that protects the network. This vulnerability has to be considered exceptionally disastrous as the protocol allows much of the key derivation to be pre-computed, making simple brute-force-attacks even more alluring to the attacker. For more background see this article on the project's blog.

R77 is now available!

It seems to be the best one ever.

What's New in R77

New Threat Emulation Software Blade

The new Threat Emulation Software Blade blocks attacks which cannot be detected by signatures. It opens inspected files inside secure emulation environments to detect malicious behavior. It can be deployed as a cloud service or as a private (local) cloud.

New Check Point Compliance Blade

This new Software Blade analyzes your environment for compliance with major regulations and international standards. Check Point Compliance Blade generates detailed reports, with best practice recommendations taken from the large Check Point library. Check Point Compliance Blade sends alerts for policy changes that can affect compliance.
