SharpRDPCheck

Use to check the valid account of the Remote Desktop Protocol(Support plaintext and ntlmhash)

Author:3gstudent

Reference:https://github.com/RDPUploader/RDPUploader

Note:The .NET Framework must support TLSv1.2. It is recommended to compile on .NET Framework 4.6

Usage:

      SharpRDPCheck.exe <RDP ServerIP> <RDP ServerPort> <mode> <user> <password>
      <mode>:
      - plaintext
      - ntlmhash

Eg:

      SharpRDPCheck.exe 192.168.1.1 3389 plaintext user1 password1
      SharpRDPCheck.exe 192.168.1.1 3389 ntlmhash user1 c5a237b7e9d8e708d8436b6148a25fa1

sharprdpcheck's Issues

Second check failed

When I try to make one more check within same process, I receive the following error:

[+] Valid:admin  admin
[!] Authentication Error (0x80004005): The Local Security Authority cannot be contacted

Here is my code:

Options.Host = "192.168.1.15";
Options.Port = 3389;
Options.Username = "admin";
Options.Password = "admin";

Network.Connect(Options.Host, Options.Port);
MCS.sendConnectionRequest(null, false);

Thread.Sleep(1000);

Network.Connect(Options.Host, Options.Port);
MCS.sendConnectionRequest(null, false);

First check is success, second and all other checks with the same credentials are always fail.

Do you have an idea why that may happen?

Authentication Error

InnerException: System.ComponentModel.Win32Exception (0x80004005): 无法连接到本地安全机构

修改internal static bool enableNLA = false;

提示The server requires that the client support Enhanced RDP Security with CredSSP
