Prangster v184.108.40.206 (last updated 06/28/2013) Copyright (c) 2013 Cylance, Inc. All rights reserved. For updates, please visit <http://www.cylance.com/>. Prangster is being released in conjunction with the Black Hat USA 2013 presentation "Black-Box Assessment of Pseudorandom Algorithms" by Derek Soeder, Christopher Abad, and Gabriel Acevedo of Cylance. Prangster is a utility for recovering information from pseudorandom application output generated using a pseudorandom number generator (PRNG) it recognizes. Its current functionality includes recovering an initial state or seed based on a sample of output (usually many orders of magnitude faster than naive brute- force), seeking to a future or previous state or seed, and generating the output that follows or precedes a given state or seed. For more information, please consult the presentation slides or white paper or the source code. Prangster is written in C# and targets the Microsoft .NET Framework 2.0. To build it on Windows, copy all of the source files (including the PRNGs and Properties subdirectories) into a directory, and either open the solution file (.sln) in Visual Studio 2012, or run the following command from the directory containing PrangsterApp.cs: \Windows\Microsoft.NET\Framework\v2.0.50727\csc.exe /out:Prangster.exe *.cs PRNGs\*.cs Properties\*.cs Adjust the above path as necessary for your system; for example, the 64-bit .NET Framework (Framework64) or version 4.0 (v4.0.30319) will also work. To build Prangster with Mono, open the solution file in MonoDevelop or run the following command: /usr/bin/mcs -out:Prangster.exe *.cs PRNGs/*.cs Properties/*.cs
