I read at many online documents that in an Internet environment an hacker can attack on user data and thus may lead to steal info in packets or modify it and resend to original destined server. But i reuire that info in diagramaic form and also some practical examples in real world. where to find them?
What exactly i want to know is that we know hacker attacks but we also know that data travels in internet from routers to routers then if from src pc to router1 to no. of routers to dst pc is path for data is then where can hacker be located here.
