just friends? thats bullshit lol... here's an idea, stop talking to her
nobody can hack you cuz they have your IP address - hacking is done through whatever box your connected through... for example DSL... you need to get into the central office (good luck) to get the PPoE credentials and phone number xxx-xxx-xxxx that you are using to dial with. DSL is by far the easiest, you can by pass teh CO and just go to the side of the house (usually at 4am) and open up that gray little box and hook into terminals... no real "hacking" required
T1, DS3, and OC lines... I have no clue - too many banks run T1... so i never tried it...
Cable - you need access to the datacenter box... having cable doesnt always mean you have a static IP because its given to you on a lease like DHCP... unless you pay the extra money to have a static
hacking use to be easy when gopher and finger ports were open.. but now they are closed by default... i think telnet is closed by default to
anyhoo... u have nothing to worry about unless the convo's are saved
