 LAND (Local Area Network Denial) attack is a DoS (Denial of Service) attack that consists of sending a special poison spoofed packet to a computer, causing it to lock up. The security flaw was actually first discovered in 1997 by someone using the alias "m3lt", and has resurfaced many years later in operating systems such as Windows Server 2003 and Windows XP SP2. The attack involves sending a spoofed TCP SYN packet (connection initiation) with the target host's IP address to an open port as both source and destination. It is, however, distinct from the TCP SYN Flood vulnerability. A LAND attack involves IP packets where the source and destination address are set to address the same device. This causes the machine to reply to itself continuously. Other LAND attacks have since been found in services like SNMP and Windows 88/tcp (kerberos/global services). These were design flaws where the devices accepted requests on the wire appearing to be from themselves, causing repeated replies.
