BlueBugging: BlueBugging is when someone illegally accesses a cellular phone using Bluetooth wireless technology. This would allow the hacker to make phone calls and to do texting via bluetooth that they BlueBugged into. This type of attack can only occur when the hacker and cellphone are within range of each other which is about 30 feet.

Botnet (Zombie PCs): Botnet is the combination of Robot and Network. Botnet computers are Internet computers that inconspicuously forward email, worms, viruses, and spam across the Internet without the users knowledge.
