2023-03-19: LLM + Clean Room: Will LLMs be the death of code copyrights?

Disclaimer: I am not a lawyer. Furthermore, remember that laws differ between countries.

Let me preface this post by saying that I don't have answers – I have only (interesting) questions. And perhaps the answer to the question in the headline eventually will follow Betteridge's law of headlines anyway.

So what is all this about?

In reverse-engineering there is a concept called clean room design. In short, it's a method of "copying" (and I'm using this term very loosely) someone's implementation of an idea without infringing on their copyrights. And while the term is a bit more generic, I will focus on it's application to software (code). In short, the method boils down to 3 steps:

  1. Reverse-engineers analyze the source software and prepare detailed documentation about how things look like and how they are done.
  2. Lawyers review the documentation to make sure no piece of code was included (or more generally: no copyrightable items were included).
  3. Software engineers implement a new piece of software based on this documentation.

2022-10-16: Rozwiązania MSHP CTF (październik 2022)

Odbywający się 17 października 2022 Sekurak Mega Hacking Party w zasadzie rozpoczął się dwa dni wcześniej od indywidualnego CTFa. W którego miałem nie grać. Bo miałem robić inne Ważniejsze Rzeczy™. Ale wyszło jak zwykle - i w sumie fajnie, bo CTF okazał się być bardzo sympatyczny.

Poniżej znajdują się rozwiązania zadań, w których udało mi się zdobyć flagę. Rozwiązania są dość skrótowe, ale starałem się mniej więcej wskazać jaką drogą poszedłem.

The full list of vulnerabilities discovered by me (including collaborative work) can be found here (please note that the list might be out of date).

The Google Application Security / Research site might also contain some of my findings.

EN Coding (selected posts)
EN Tools and libraries
  • PiXieServ is a simplified PXE (network boot) server for Windows and Linux-based OS, created for testing of very small home-made OS. See also the post about it.
  • ExcpHook, a system-wide exception monitor for Windows XP 32-bit. Useful if you're fuzzing something that doesn't like having a debugger attached.
  • Ent is an entropy measuring tool for reverse engineering reconnaissance (see also a post explaining how to use it).
  • HiperDrop is a simple command line process memory dumper for Windows, with a few different work modes.
  • asmloader - this little app executes headerless machine code (compiled assembly code). It's meant to be an aid in learning/teaching and playing with assembly, as well as the right tool when you just need to execute some machine code.
  • NetSock is a simple socket/networking lib/wrapper for C++ I've wrote back in 2003 and update from time to time - I use it for most of my network-enabled projects.
