Credential Guard was supposed to end credential dumping. It didn't. @bytewreck just dropped a new blog post detailing techniques for extracting credentials on fully patched Windows 11 & Server 2025 with modern protections enabled.

Proof-of-Concept tool for extracting NTLMv1 hashes from sessions on modern Windows systems.
P.S. Previously, crack.sh operated a free service for performing rainbow table lookups to recover NT hashes from NTLMv1 responses, but was recently shut down due to maintenance issues. In its absence, a new free service was published at ntlmv1.com.
