If you're new to participating in capture the flag (CTF) competitions, it can seem overwhelming! You may even find yourself looking at a challenge and wondering; How do I even begin? What kind of file is it? Wait! Wait! something is broken. Let this page serve as a calm place to get started. Trust us when we say each challenge works. Once a challenge is developed, it is audited by an audit team, and then once more by a review team prior to going live. So each challenge is solvable. 
Each challenge can be solved using free and open source tools on any of the big three platforms; Windows, macOS, and Linux. In fact when creating the challenges, the development team tests it on all three platofrms before it is turned over to the audit team. 
Great, but that still doesn't answer the question about what a CTF is! A CTF can be tons of different things, most often it is a question or series of questions of one or more topics. This CTF in particular encompasses topics consistent with digital forensics and incident response or DFIR for short. 
CTF challenges often require the same mentality needed to solve a riddle or a puzzle. In this CTF specifically, we ask questions which may require the repair of a file header, using something like Base-64 to decode a BLOB, solve a crossword puzzle, or figuring out the cryptographic scheme to recover a password. Challenges have been modified to impede using automated tools for analysis. 
If you have never seen a CTF before, this is a great introduction; and we invite you to check out a favorite CTF of the NW3C High-Tech Crime Section, the Flare-On Challenge hosted annually by FireEye.

'What a great CTF. You guys at Belkasoft always make sure to take it to another level. I had the best experience participating in your CTFs!! I really loved Brave browser parsing from Belkasoft Evidence Center. It saved me a lot of time, while I noticed some other commercial tools haven't yet supported it. Also, the cryptocurrency additions are to the point if we consider the crypto madness of the last months. Great job again and thank you!

Welcome | OOO archive | DEF CON CTF
Welcome, hackers. This is a live, playable archive of DEF CON CTF challenges. 
Brought to you by the Order of the Overflow, 2018-2021 host of DEF CON's official CTF.
Challenges are not particularly malicious or dangerous, but they are vulnerable by design (that's the game!). Containers isolate them, but it's up to you to play safely. 
We're archiving more challenges and appreciate issue reports and suggestions. Just be mindful that running the CTF is tough and has priority. General archive FAQ

Digital (Computer) Forensics Tool Testing Images
Testing in the public view is an important part of increasing confidence in software and hardware tools. Developing extensive and exhaustive tests for digital investigation tools is a lengthy and complex process, which the Computer Forensic Tool Testing (CFTT) group at NIST has taken on. 
To fill the gap between extensive tests from NIST and no public tests, I have been developing small test cases. The following are file system and disk images for testing digital (computer) forensic analysis and acquisition tools. They were submitted to the Computer Forensic Tool Testing (CFTT) e-mail list on Yahoo! Groups. The results can be found in the CFTT list archives and in the Test Report Tracker.
