I was reading tutorials on proxy and I configured my Firefox with free IP proxy. I'm wondering. Is it really true that browsing and doing stuff under proxy I am 100% anonymous? I cannot be detected right? If that's case why hackers don't use when they're gathering information about their target? I mean I read pages and tutorials about hacking (ethical beginner) and they don't really mention using proxy. When hackers get caught they get caught by their IP right? so Why didn't they use proxy servers instead? Bottomline what are the drawbacks of using proxy, it must be something behind it.
