CTF Write-ups

If you are new to Capture The Flag (CTF) competitions, this section will explain all that you need to know.


A CTF is, usually, an online competition where participants attempt to solve challenges for points. The challenges address very specific topics but have multiple solutions. As this suggests, a great deal can be learned from your own solution as well as someone else's. The final result of a solution is obtaining the flag. Note: Most CTF's to date dynamically generate most flags hence copying any that may be presented in the solutions below will  not help you. The documents below are what are called write-ups - descriptions to solutions to CTF challenges. Write-ups offer a great introduction to many Cyber concepts from forensics, to binary exploitation.
