Baiting
The most common version of this tactic can come in the form of a USB stick you find near your car, or a free music in your mailbox. These come pre-filled with malware that infect your computer as soon as you insert the drives. In a well targeted attack, they are custom made for your computer and likely evade common anti-virus software. But baiting can also be much less technical. It could take the form of a free tour during which you are befriended and tricked into revealing sensitive information, or you have your equipment bugged.
