There is a loophole in the network credentials of the windows system. We must pay attention to it.

local area network or public network two computers with windows system, if open sharing, is encrypted, then access will be asked to enter network credentials, then what is the network credentials? Simply understood as a pass to the other party's computer. Here is a small experiment to understand the harm of network credentials, but it is really not small.

Environment:

windows 2008 R2

IP address: 192.168.80.129

windows 7

IP address: 192.168.80.134

1, now Windows2008R2 installed after the system did not close the default sharing in time, now we use Windows 7 to access his default sharing.

2. Successfully entered default sharing

3. Check our local network credentials

4, we can use known network credentials to shut down, restart, if the other computer to open the network registry and other functions we can also control his registry, so as to fully control this computer, below we restart the other computer using DOS command.

5. Check the restarted server

Summary:

The harm caused by network credentials is great, especially for some people who do not understand computers and networks.

2. After sharing with others, be sure to delete network credentials on others 'computers (net use * /del)

3. After installing the system, turn off default sharing for more important computers.
