El fin de la era de la seguridad proporcionadas por las claves WPA/WPA2 se acerca a su fin. Las GPUs demuestran ser capaces de reducir el tiempo de crakeado. De la página de Pyrit, una herramienta GPL para crakear WPA/WPA con GPUs:
Pyrit takes a step ahead in attacking WPA-PSK and WPA2-PSK, the protocol that today de-facto protects public WIFI-airspace. The project's goal is to estimate the real-world security provided by these protocols. Pyrit does not provide binary files or wordlists and does not encourage anyone to participate or engage in any harmful activity. This is a research project, not a cracking tool.
Pyrit's implementation allows to create massive databases, pre-computing part of the WPA/WPA2-PSK authentication phase in a space-time-tradeoff. The performance gain for real-world-attacks is in the range of three orders of magnitude which urges for re-consideration of the protocol's security. Exploiting the computational power of GPUs, Pyrit is currently by far the most powerful attack against one of the world's most used security-protocols.
