What are hackers capable of?

Hackers are capable of doing anything on the internet or anything that involves internet and satellite. They can tap into your phones and hear what you're doing. They can hack your webcam and see (always cover you webcam or unhook it). Most advanced hackers are to hack into people's networks (schools president's pc-takes 20 yrs to even with a super computer, offices, etc.) When using the internet or anything, BE SAFE because anything can happen. Use stuff like Kaspersky or any Antivirus.
