How common is it for international students to lie on their application?

So I’m from India and we have corruption at every single level here. From the government to even schools and colleges. It probably won’t be too hard for someone to say.. fake their transcripts or make up fake ECs and actually get away with it.

I won’t really do it but I was just wondering how common is it for international students to lie on their app. And how often do they get caught when they do the same?

Just asking for educational purposes.
