Explanation/Notes: A common method attackers use to install a Trojan Horse program or other malicious software is to change the name of an existing program, and then call the help desk complaining that an error message is displayed whenever an attempt is made to run the program. The attacker persuades the help desk technician to run the program himself. When the technician complies, the malicious software inherits the privileges of the user executing the program and performs a task, which gives the attacker the same computer privileges as the help desk employee. This may allow the attacker to take control of the company system.
