SMBLoris NBSS Denial of Service

The SMBLoris attack consumes large chunks of memory in the target by sending SMB requests with the NetBios Session Service(NBSS) Length Header value set to the maximum possible value. By keeping these connections open and initiating large numbers of these sessions, the memory does not get freed, and the server grinds to a halt. This vulnerability was originally disclosed by Sean Dillon and Zach Harding. DISCALIMER: This Metasploit module opens a lot of simultaneous connections. Please check your systems ULIMIT to make sure it can handle it. This Metasploit module will also run continuously until stopped.
