Summary:
This event is generated when the NET command is used for message sending, remote null session connections etc.

--
Impact:
Information gathering.

--
Detailed Information:
An attacker tried to access the "net" command on a host.

The Windows "net" command is usually not accessible through a webserver, check for possible directory traversal attacks.

Net cannot be used to gain full control of a host, but can establish null sessions on weakly protected Windows hosts for example or to gain information on the network the host is connected to.

--
Attack Scenarios:
A web request for the command "net".

--
Ease of Attack:
Simple.

--
False Positives:
A valid URL request containing the string "net.exe" can generate an event.

--
False Negatives:
None known.

--
Corrective Action:
Protect "net.exe" from remote usage. Remove the file completly if it is 
not needed.
