#2For Beginners, I'd begin with defining "CTF".
I don't see that defined anywhere in the article.
From some googling, I guess it's a "Capture the Flag" challenge? It's worth stepping back and explaining that general concept.

Yes, the goal of these is to obtain a flag.

#4> Up to how many characters does it loop? Here’s how I found it. Basically, our password must be of 7 characters in length.
One way to see this without running the program is look for where $ebp-0x24 is set:

In short, replace "CTF" with "exercise". They are basically challenges that go by the name Capture The Flag: https://trailofbits.github.io/ctf/

It's about obtaining some hidden information (the "flag") in a computer security context, where you're either trying to penetrate a hardened (computer) target, or reverse-engineer an obfuscated binary.
It's a constructed exercise, as opposed to a "live" situation.

this is now an hn trope (complaining about some jargon in the title). newsflash the meaning of the title isn't "Linux reverse engineering for beginning humans that don't know anything about the universe, language, or electricity" because then you'd need to define Linux and engineering as well. the meaning of the title is always "____ thing for people that know a little about ____ thing but not everything". i think it's a very reasonable assumption on the part of the author that the only people he/she is accountable to for the intelligibility of such a title is someone who searches out the article, since after all this isn't about regattas nor is it assigned reading in some kind of primary education course. this kind of bad faith reading of these articles is beyond worthless (and certainly doesn't merit a comment). what I can't for the life of me understand is why hn is like the epicenter of this kind of pseudo-critical engagement with media - neither Reddit not Facebook has these kinds of comments nearly as often (nor the closely related "... didn't read after ___" where ___ is a word in the first sentence). my hypothesis is that it has something to do "intelligence signaling" because people wrongly believe that being critical is an indicator of intelligence.

Are you trolling, joking or just misinformed? CTF in the context of the OP absolutely means Capture the Flag.
