Revision as of 01:44, 23 October 2013

This page describes large-scale corpora of forensically interesting information that are available for those involved in forensic research.

Disk Images

The Real Data Corpus.
Between 1998 and 2006, Garfinkel acquired 1250+ hard drives on the secondary market. These hard drive images have proven invaluable in performing a range of studies such as the developing of new forensic techniques and the sanitization practices of computer users.
Garfinkel, S. and Shelat, A., "Remembrance of Data Passed: A Study of Disk Sanitization Practices," IEEE Security and Privacy, January/February 2003.
The Honeynet Project Forensic Challenge.
In 2001 the Honeynet project distributed a set of disk images and asked participants to conduct a forensic analysis of a compromised computer. Entries were judged and posted for all to see. The drive and writeups are still available online.
http://www.honeynet.org/challenge/index.html
Other challenges were released in 2010 and 2011, and two contained partial disk images.
Challenge 7: Compromised Server
Challenge 9: Mobile Malware
Honeynet Project Scans of the Month
The Honeynet Project provided network scans in the majority of its Scan of the Month challenges. Some of the challenges provided disk images instead. The Sleuth Kit's Wiki lists Brian Carrier's responses to those challenges.

In the competition, you will have to analyze a submitted disk image for incriminating evidence.

The PyFlag standard test image set
http://pyflag.sourceforge.net/Documentation/tutorials/howtos/test_image.html
The Digital Forensic Research Workshop's Rodeos and Challenges
Several of the Rodeos and Challenges from DFRWS released their data and scenario writeups. The following had disk images as parts of their scenario:

Memory Images

The Volatility FAQ provides a listing of openly-available memory images.

Network Packets and Traces

DARPA ID Eval

The DARPA Intrusion Detection Evaluation. In 1998, 1999 and 2000 the Information Systems Technology Group at MIT Lincoln Laboratory created a test network complete with simulated servers, clients, clerical workers, programmers, and system managers. Baseline traffic was collected. The systems on the network were then “attacked” by simulated hackers. Some of the attacks were well-known at the time, while others were developed for the purpose of the evaluation.

WIDE

The MAWI Working Group of the WIDE Project maintains a Traffic Archive. In it you will find:

  • daily trace of a trans-Pacific T1 line;
  • daily trace at an IPv6 line connected to 6Bone;
  • daily trace at another trans-Pacific line (100Mbps link) in operation since 2006/07/01.

Traffic traces are made by tcpdump, and then, IP addresses in the traces are scrambled by a modified version of tcpdpriv.

Wireshark

The open source Wireshark project (formerly known as Ethereal) has a website with many network packet captures:

NFS Packets

The Storage Networking Industry Association has a set of network file system traces that can be downloaded from:

Other

Github user "markofu" has aggregated several other network captures into a Git repository.

Email messages

The Enron Corpus of email messages that were seized by the Federal Energy Regulatory Commission during its investigation of Enron.

The NIST TextREtrieval Conference 2007 has released a public Spam corpus:

Email Messages Corpus Parsed from W3C Lists (for TRECENT 2005)

Text Files

Log files

CRAWDAD is a community archive for wireless data.

CAIDA collects a wide variety of data.

DShield asks users to submit firewall logs.

Text for Text Retrieval

The Text REtrieval Conference (TREC) has made available a series of text collections.

American National Corpus

The American National Corpus (ANC) project is creating a massive collection of American english from 1990 onward. The goal is to create a corpus of at least 100 million words that is comparable to the British National Corpus.

British National Corpus

The British National Corpus (100) is a 100 million word collection of written and spoken english from a variety of sources.

IEEE VAST Challenges

IEEE Visual Analytics Science & Technology Challenges

Images

[1] UW Image Database
A set of freely redistributable images from all over the world, used for content-based image retrieval.

Voice

CALLFRIEND

CALLFRIEND is a database of recorded English conversations. A total of 60 recorded conversations are available from the University of Pennsylvania at a cost of $600.

TalkBank

TalkBank in an online database of spoken language. The project was originally funded between 1999 and 2004 by two National Science Foundation grants; ongoing support is provided by two NSF grants and one NIH grant.

Augmented Multi-Party Interaction Corpus

The AMI Meeting Corpus has 100 hours of meeting recordings.

Other Corpora

  • Under an NSF grant, Kam Woods and Simson Garfinkel created a website for digital corpora [2]. The site includes a complete training scenario, including disk images, packet captures and exercises.
  • The Canterbury Corpus is a set of files used for testing lossless compression algorithms. The corpus consists of 11 natural files, 4 artificial files, 3 large files, and a file with the first million digits of pi. You can also find a copyof the Calgaruy Corpus at the website, which was the defacto standard for testing lossless compression algorithms in the 1990s.
  • The UMass Trace Repository provides network, storage, and other traces to the research community for analysis. The UMass Trace Repository is supported by grant #CNS-323597 from the National Science Foundation.
  • UCI's Network Data Repository provides data sets of a diverse set of networks. Some of the networks are related to computers, some aren't.
