The SMB protocol can be used on top of its TCP/IP protocol or other network protocols. An automated exploit uses reverse connect or bind listener payloads and does not abuse normal authenticated control mechanisms. Passive exploits report shells as they happen can be enumerated by passing -l to the sessions command. User level protection was later added to the SMB protocol. Or if you know that the target system has a specific vulnerability that you want to test, you can run the exploit that targets that particular weakness. To exploit this, the target system must try to authenticate to this module. North Holland Publishing Co Determine what users exist via brute force SID lookups. From here, quit being lazy and do research. Exploits SMB Server Message Block, A protocol running on the application layer allows us to share files between two OS within the network.
