You may notice that the following tips are non-technical, that’s because I honestly believe my best hacking tips are not actually technical points rather concepts that have helped me overcome barriers and enjoy a well-paid, fruitful career.

Don’t Assume Anything

The biggest things that have got me stuck on jobs, during CTFs and even exams like OSCP is a very simple point, I assumed things were harder than they were. I can’t tell you how many times I have done some elaborate steps to get what I need, only to find out later that the solution was much easier and often staring me right in the face. I have also experienced the other side of the coin, like trying to crack certain hashes when I just started out only to realise I would have to wait a million years to crack it. The point? Don’t ever assume, in fact, the opposite, deeply research, choose carefully and strike hard. Watch these talks to see surgical approaches to finding 0days.

Don’t Learn to Hack, Hack to Learn

This one is easy, sure, go learn all you can but the only way to learn is to do. That said, I keep these posts short as to be a top-up/boost in certain areas so you can take those tips and then practise using them in your own ways, after all that is what hacking is about, taking what we know and trying new things with it. I also say another thing which goes one step further, if you want to break it, learn how to make it; I can’t even begin to tell you how many times experience from building/deploying something helped me to exploit it, take this all the way and deploy new types of operating systems, new apps and build things from the ground up.

Learn Everything from a Macro Level First

This is a pretty simple concept, one I learn from programming which I will use an example. I can write in a number of languages, how many? I don’t know, I don’t count anymore. I don’t count because answer is any one I want to, how? I can do this because I learn things from a macro perspective.

In our example, programming, there are only a certain number of things you will want to do:

  • Persist Data
  • Do Arithmetic
  • Hold Multiple Values in Array’s (or language equivalent)
  • Call Code
  • Compare Values
  • Set Up Variables
  • etc..

This means you can learn one language well to understand how these things might work, then you can simply Google how to do specific things in the new language. Sure there are differences like syntax (just use Google!), and you may have to do things like manage memory yourself; but these are small things to overcome when you realise it’s a language specific issue. This makes it so much easier to write new code in a new language, imagine doing it the other way and approaching it like you had to learn all about a new language each time.

This same concept applies to security, generally speaking there are actually only a few macro vectors, figuring out their platform/level nuances is half the fun but again much easier than thinking all vulnerabilities are different.
