Once the system configuration is known, then exploits can be selected. An example of an exploit that takes advantage of system-specific vulnerabilities is described in the following statement from the U.S. Computer Emergency Response Team (US CERT): Exploit code has been publicly released that takes advantage of a buffer overflow vulnerability in the Microsoft Private Communication Technology (PCT) protocol. The vulnerability allows a remote attacker to execute arbitrary code with SYSTEM privileges. [see http://www.us-cert.gov/current/current_activity.html for more information]

If the system is connected to the internet and is listening for an RDP signal, it will respond if a remote user asks it is active. The remote user will then be provided a login screen of the victim’s desktop without letting the victim know anything about it. The attacker would be asked to enter the password for getting remote access through RDP. If the victim’s RDP is poorly configured, i.e., no strong password is enabled, then it would be easy for the intruder to get remote access to the system.
