Information takes many forms. Some of these forms are easy to understand and others less so. Some are hardly even recognizable.
How do you know when you’ve found something interesting? When is that string of random-looking gibberish actually random gibberish and when is it something you can pick apart and make use of? What about that giant blob of text that may or may not have interesting parts inside it?
CyberChef – a free browser-based tool from GCHQ – is a great place to start. It knows about lots of different data formats and encoding rules and lets you string them together into recipes to help you pluck out just the parts you need. In this webcast, we’ll look at some of the ways CyberChef has helped make sense of confusing things, how it compares to other tools you may already know, and how you might make it part of your own adventures.
