Distributed Password Recovery using Geforce 8 Video Cards


The software Elcomsoft Distributed Password Recovery was designed for distributed recovery of lost passwords providing hardware acceleration for NTLM password recovery using GeForce 8 video cards which speeds up the process by a factor of up to 25).

The software package consists of three components which can act independently from each other: The agent, the server and the console. The server is started at the beginning of the password recovery process. Then a new task is created using the console (on the same or a different computer) and Agents that connect to the server are assigned parts of the work that has to be done.

Agents then report back to the server once their work is done and receive another part until the password is recovered. The Agents post a status message to the server once every 60 seconds.


The server receives its task from the console and distributes it among the agents. The console in its turn is designed to manage the server it is connected to and the agents that are registered on the server. The agents are registered on the server when they connect to it for the first time.

Among other formats Microsoft Office 2007 and prior documents, PGP, Adobe Acrobate PDF documents, Windows NT, XP, Vista logon passwords, Windows syskey passwords and several other are supported by Distributed Password Recovery.

The product comes at a price though which is only affordable to companies. I still thought it would be nice to write about it due to its hardware acceleration feature that I never heard about before.

    a similar project has been attempted with the PS3…

    i think makes more sense to use PS3 than geforce 8 cards since PS3’s cell processor is essentially a parallel processor and it is this kind of processing paradigm that is required to crack passes
