However, the flip side is that the Internet also affords online scammers, hackers, and identity thieves access to personal computers, information, finances, and much more. According to the Federal Trade Commission, there are millions of victims of identity theft a year. It's often difficult to know how thieves obtain a victim's personal information, but instances of ID theft often start when online data is stolen.
