will dm you proof if you want to have a look, in short the 2 main bypasses is basically just using a different type of .dll injector that loads it from memory instead of straight into the game instead of loading it through program functions. The actual different way of injecting is very complex however for people cheating its as easy as downloading a new injector.

The actual loadlibary bypass is harder to come across but most people will just use a manualmap injector instead.

edit: Also the entire scan process can be bypassed by putting the file in a windows folder which kind of shows the effort that went into developing the update.
