Multi-factors, support of FIDO, and the use of virtualization technology to secure credentials were all slated to be in its latest and greatest OS.
Ntlmv2 Authentication Windows 10 Late LastWith the general release of Windows 10 late last month, we now get to see whats in the sausage.
In the very first bullet point, they announce Windows Hello, which is Microsofts take on password-free authentication, using either facial, thumbprint, or iris recognition for validation. Its described as a way to protect corporate identities by containing them in the hardware-based secure execution environment. As I read more, it was beginning to look like this was the long awaited PtH messiah. The hash of the password remember hashing is at the core of Windows NTLM challenge and response authentication protocol. Ntlmv2 Authentication Crack Hashes ToOnce inside a system, hackers love PtH because they dont have to crack hashes to take over a users identity. In an SSO environment, the computing world most of us live in, you enter passwords once when logging in to your corporate laptop. When you need to access other services, Windows just dips into LSASS to pull out the credential the hashed password so you dont have to re-enter it. Ntlmv2 Authentication How To Reduce TheTo its credit, it sort of recognized the problem and has given very good advice on how to reduce the risks of credential stealing see this paper. In Windows 10, the designers reworked the LSASS process so that it lives in its own virtualized container. Yeah, its using similar ideas and techniques to those found in virtual machines that enable a host operating system to run various guest operating systems. Youll have to read the paper to understand the fine points note the use of the words hypervisor and ring levels. The developers left the LSASS programming logic intact to continue supporting credential processing as before. The memory space, though, is walled off from other apps with Credential Guard acting as the gateway. So you can think of Credential Guard as the guardian of the wormhole between its special memory space and everything on the other side. Nevertheless, the technology is quite interesting and really does seem to finally close off PtH. It may still be possible in the future, but it will require a far more sophisticated effort than is currently the case.
