The TCP/IP-Stack of the Microsoft Windows XP/Vista Operating System is vulnerable to a remote resource exhaustion vulnerability. By taking advantage of this vulnerability, an attacker can cause a connection's Transmission Control Block (TCB) to remain in memory for an indefinite amount of time without the need for the attacker to further maintain the connection's activity.

Its aim is to provide a reliable and fast TCP-SYN-port-scanner which performs sophisticated timing based on the use of so called "trigger"-packets. The port-scan is performed in 2 steps: First the scanner tries to find packets, to which the target responds ("triggers"). Second, the actual port-scan is performed. During the scan, the triggers, which were found in the first scanning-phase, are used to determine the optimal speed at which the target may be scanned.
