I'm performing a pentest for my client.
So after scanning my client's network I understood they're using IIS 4.5 and windows server 2012 (or 2012 R2)
I know the systems are real old.
And there are known exploits for them.

The tricky part is I have to stay hidden and I only have my own credentials for logging in to the asp page. (Uploading a script is almost crossed cuz it will reveal my identity)
Also I have access to the local network with some of the other employees user/pass.

Any recommendation for exploiting and staying hidden at the same time ?

One more question : will exploits for newer versions work for the older ones necessarily?

Dealing with YouTube's shitty recommendation algo for several years now makes me lose faith in recommender systems in general.

!Long Rant!!
Got inspired by Ewin Tang's paper on figuring out a classical computer algorithm for recommendation systems inspired by quantum computers and started to write up an email to a professor in some Quantum research I'm interested in doing. As a high school student, it's VERY daunting to start. Been researching the prof and I'm super excited but it's nerve racking! Like what if she doesn't even open her research projects to high school students and I'm wasting my time? In case, I am planning on asking if there is anyone else I should contact. I'm focused on doing this research with McMaster since it's nearby but I'm really doubting myself. People my age who do this stuff are phenomenal and I feel like I wouldn't live up to that. You guys are probably a lot more experienced in this so if you've got any advice or tips, let me know.

Ability to understand all machine learning models to modify code and those models directly and create better ones every time.

I would take existing ml model, modify it by hand to create better one, win some multimillion dollars competitions and make them open source.

Eventually all recommendation systems, text to speech, speech to text, music generation, movies generation etc would be opensource.

This would either destroy or boost all modern economy but for sure it would make harm to corporations and make them cry.

That would be fun to see.

I need recommendation for site/community to improve my (clean) code style?

And, in more general, what are your ways to improve code style and programming way of thinking - more oriented towards bigger picture of application/systems (patterns, architecture, etc.)?
