Network authentication crack

The standard procedure of compilation on most UNIX systems usually goes like this:. Ncrack has been ported to Windows and has been tested on Windows XP so far.

Since this is an experimental version, please notify us for any problems or successful results on other platforms. There is a ready-to-use Windows installer available, which makes the whole procedure of getting and deploying Ncrack, painless:. Ncrack release Windows installer: ncrack Guru99 is Sponsored by Netsparker. Netsparker, the developers of Proof Based Scanning technology, have sponsored the Guru99 project to help raise web application security awareness and allow more developers to learn about writing secure code.

I quickly wondered if it would be feasible to use this utility, and other native tools within Windows, to capture NTLMv2 network authentication handshakes. Other network authentication protocols exist for Windows Active Directory - most notably Kerberos - but NTLMv2 is still widely used on today's organizational networks.

As such, many tools in contemporary penetration testing focus on intercepting NTLMv2 authentication handshakes, which can be assembled into crackable password hashes or relayed to other hosts on a network to gain access without the need to crack hashes.

The most infamous of these tools is Responder , which has been a staple in the penetration testing arsenal for many years. Both utilities output. ETL files, which are structured differently than the more popular. PCAP and. The following describes how to use each tool to capture network traffic. We will focus on port , which is used to access network resources over the SMB a.

CIFS protocol. ETL files into a. PCAP format. While there are tools, such as Microsoft's etl2pcapng , that attempt to convert. For example, a telnetd might make you wait 3 seconds before it tells you that a password is wrong. But that's not such a big difference if you've got dozens of other threads cracking against the same service at the same time.

It should do that in a flexible enough way that it can include optimizations for each. For example, some services will let you try 3 attempts per connection before you have to disconnect and try again. It should be able to use features such as keepalive and pipelining to the extent doing so helps. We should take the best from each, and add our own great ideas and strong implementation. These are my ultimate goals, but they may not all be met by the end of SoC ' What do you folks think?

Would you find such a tool useful? What sort of features and functions would you want? Any key requirements I've missed?
