You'd be surprised how many professional hackers - the ones that intelligence agencies hire/train/employ - start with close to zero prior knowledge on topics like cybersecurity, when they're going through selection.

If you have solid knowledge in CS fundamentals and the right mindset/motivation, that tends to be enough.

I will eventually read through this because I have a reasonably good handle on Python/Go, but don’t have any experience with Rust. This book will help me focus on the parts of Rust that I am most interested in given my current InfoSec work.

Please, spare us the gatekeeping.

I feel as though buying a book like this is a great way to start learning about black hat work. Doing things out of curiosity is how everyone starts in a field like cybersecurity.
