"Exploit Checker" Help

Hey, I'm new to I guess, Coding in gmod and I wanted to know how I could check for exploits. I read an outdated post teaching how to use notepad++ to check for net.start in servers you've joined whilst scripthook is on (aka in the folders in which the servers shit was pulled.)
I've gotten that far, I just want/need to know how i can check which addons can be exploited/How would I exploit them (or run them when i have the exploit written?, I'm guessing as a lua.) thank you so much for any help in advance.

Make an infinite numeric for loop, use util.NetworkIDToString, store the value in a table, if it returns nil then break the loop.

Use the table in your exploits to check if they exist.

Learn how to make a numeric for loop and use math.huge as the limit.
Cache util.NetworkIDToString(i)
if cached string then table[cached string] = true else break end

That's a while loop.

Maybe you should learn basic Lua.

Stop being so fucking shitty. It isn't my fault you can't figure out something as simple as this.
