A type of Denial of Service (DOS) attack which confuses and crashes a number of Operating Systems (especially Windows 95) or uses up the CPU so the system can't do anything else (such as in Windows NT). A Land Attack is performed by launching TCP/IP packets with the same source and destination IP address and port. There are freely available tools that anyone can download and use which will perform a Land Attack.
