Hey! Lovely video as always. Just wanted to say, the part where the hash of the password has to end in "001" in order to be valid and you've found one to be "abkr". You overworked the code a bit... For example you could have just made a single for loop going from a number 0 to 10000000, every number to string and just hash that, much easier and way less code to loop through numbers than ascii characters. The one i've found is 5265 with its hash being 'f127a3f714240273e254d740ed23f001'.

I was able to follow pretty easily up to privilege escalation because of previous knowledge, but even the prev esc part was understandable because of your thorough explanations! Also loved to see that you actually took the time to code some brute forces (hash, code, and even directories (even though you didn't write the code yourself)). Sometimes it really does take some dirty, boring, and time-consuming work to get somewhere.

Fun fact: Because cryptographic hashes map evenly from all possible inputs to all possible outputs, it doesn't really matter what you're hashing. You could start at the number zero, take the hash from that and keep incrementing it by 1 until you hit your target hash. (or you could hash a random string/number every time) Because every hash outcome has the same probability to occur, (and all hashes ending in "001" also have the same probability) you will find your target hash just as quickly. Note: I converted the number to string here due to readability of the code. More straightforward computationally would be to simply hash bytes and increment those bytes until you hit your target. import hashlib i = 0 while True: m = hashlib.md5(str(i).encode()).hexdigest() if m[-3:] == '001': print(f'the md5sum of `{i}` is `{m}`') break i += 1

I'd love to see more live competition stuff like the old king of the hill livestreams, especially the older streams when they didn't know the rooms yet. They don't make new rooms for those enough so it's just autopwn scripts for them all by now with the only competition being fighting for the king file and bricking the box which isn't really as interesting. HTB battlegrounds was interesting but felt too formal, I liked THM KotH streams since they were generally more laidback.

John: Some ideas for you: I don't know every video you have on here but: "This is what an attack looks like on screen on Windows" "This is how the colonial pipeline happened and what I would have done to attempt avoiding it" "The is how pen testers and bug bounty did their job in the Mitnick days before Burp Suite existed" "This is how pen testers did their job before metasploit existed" "This is probably why Russian and Chinese hackers are so good" I'm thinking video like these would separate your account and put it at a new level of you have the time Nice to meet another hacker!!

Thanks for another great video. One question though: Why do you call the python script by invoking `python` when you have a python shebang set? Or asked the other way around: Why do you set a shebang when you don't chmod +x the script and execute directly?
