  5. “A $1000 computer can process 3.3 billion passwords per second… a professional can make thousands of dollars a day selling your information on the black market.” (PCPro.com)

  6. It’s just a matter of time • Dictionary Attacks: • “GoBuffs!” a couple minutes • “P@$$w0rd1” a couple hours • Brute Force: • “fjR8n” in 24 seconds • “%fjR8nQNUc5GPj9” would take over ten years • *Extra credit: 15 characters or more forces windows to store passwords differently – which breaks certain attacks.

  7. Hacking is big business • 2011 = 12.5 billion in reported losses • Some estimates put that number closer to 10 times as much. www.hotforsecurity.com
