Explain how it would give a potential intruder an additional advantage if he can spend a week stealthily watching the behaviors of the users on the computer he plans to attack.

Normally, the attack comes from an intruder who already studied the victim's behavior.

> The attacker can create a database from the history of browsing of the possible victim and then create an attack based on the victim's behavior of browsing.

> If the attacker has access to the user directory he can put the executables files in those folders.
