Decrypting UserAssist registry keys Sun, 07 April 2013 14:18:00 +0200 Windows systems maintain a set of keys in the registry database (UserAssist keys) to keep track of programs that executed. The number of executions and last execution date and time are available in these keys. The information within the binary UserAssist values contains only statistical data on the applications launched by the user via Windows Explorer. Programs launched via the commandline (cmd.exe) do not appear in these registry keys. From a forensics perspective, being able to decode this information can be very useful. |

WinPrefetchView reads information contained in Windows prefetch files Tue, 02 April 2013 22:22:00 +0200 Each time an application is run in a Windows based system, registry keys and a prefetch file (%windir%\*.pf) which contains information about the files loaded by the application are created. The information in the prefetch files are used for optimizing the loading time of the application for the next times it will be run. WinPrefetchView is a small utility that reads the prefetch files and displays the information stored in them (files used, files loaded on Windows boot). |

pescanner.py, a PE analyzer Sun, 03 Mar 2013 15:26:00 +0100 pescanner.py is a PE analyzer written in python by the authors of the Malware Analysts Cookbook. It is available in the companion DVD shipped by the book but is also freely distributed on Google code. The script has the ability to detect files with TLS entries, files with resource directories, suspicious IAT entries, suspicious entry point sections, sections with zero-length raw sizes, sections with extremely low or high entropy, invalid timestamps and file version information. Among other things, this script is helpful to understand the behavior of an executable and classify malwares (UPX packed, trojan downloader, trojan dropper, ...). |

From AlienVault SIEM alarms to identification of infected files on the compromised machine Mon, 25 Feb 2013 13:31:00 +0100 This article shows how to dig into the memory dump using volatility to identify malwares found on a Windows XP machine, initially detected with the AlienVault SIEM. |

Volatility framework explained Sun, 24 Feb 2013 08:26:00 +0100 The Volatility Framework is a completely open collection of tools, implemented in Python under the GNU General Public License, for the extraction of digital artifacts from volatile memory (RAM) samples. The extraction techniques are performed completely independent of the system being investigated but offer visibiltiy into the runtime state of the system. The framework is intended to introduce people to the techniques and complexities associated with extracting digital artifacts from volatile memory samples and provide a platform for further work into this exciting area of research. |

Yara to analyze malwares Sun, 17 Feb 2013 18:18:00 +0100 Yara is a very powerful tool aimed at helping malware researchers to identify and classify malware samples. It is based on signatures files that offer a great flexibility: hex, string, regular expressions, ... Yara is available as a standalone application, or a python port that you can use for your own developments. Yara is also included as an available plugin in volatility. |

File Transfer Via DNS Sat, 16 Feb 2013 14:51:00 +0100 You guys already know DNS encapsulation (e.g. dns2tcp) to transfer data over DNS but I've found a very interesting post from Johannes Ullrich who introduces a relatively stealthy concept to transfer data via DNS requests. It consists of sending hex parts of a file as part of DNS requests on one side and to capture and split these DNS requests on the other side. No specific tool is required but tcpdump and xxd. |
