Hacking attacks can be performed in a couple of ways:
1. Hacking computer that have their firewalls disabled or not installed. Hackers also crash on wireless networks that do not have router firewalls enabled or installed. 2. Sending out email attachments that contain keystroke loggers or other malicious software that embeds itself unknowingly on its victims' computers. These programs record every keystroke done by the victims in their computer and send it out when the victims goes online. 3. Attacking individual consumers who use old versions of browsers. These old browsers have certain vulnerability that is being improved with every new editions of said browser. If you use an older browser, chances are, hackers can easily enter your computer because of the browser that you use. 4. Exploiting unsecured wireless networks or secured wireless networks that have very weak or poor password protections. Hackers can easily get inside a wireless network and view what everyone in the network is viewing in their screen. When you enter your personal information, a hacker on the other end might be recording it to be used for their identity theft activities. 5. Previous employees or trusted users who access their company's computer using their insider knowledge to get inside. These people are often disgruntled when they leave the company so they seek to get even by hacking into the system.
