| If you got a chance to access your target computer, you should try putting keylogger or remote desktop program AKA trojan into their computer, it'd be easier to steal their password. If your target appears to have antivirus program, don't forget to exclude them from being deleted by antivirus, many antivirus has an option to create a list of virus to exclude or ignore it. Also, if your target has firewall, don't forget to allow your remote desktop or trojan to go out.
You can get more than just WoW password this way. You may also got e-mail password or maybe even credit card info too. |
