Microsoft is planning to kill off NTLM (New Technology Lan Manager) authentication in Windows 11 and above. Let's speedrun coercing hashes out of a few more things before it fades into obscurity over the next twenty five years or so. There will be a deep dive on several new bugs we disclosed to Microsoft (including bypassing a fix to an existing CVE), some interesting and useful techniques, combining techniques from multiple bug classes resulting in some unexpected discoveries and some absolutely cooked bugs. We’ll also uncover some defaults that simply shouldn't exist in sensible libraries or applications as well as some glaring gaps in some of the Microsoft NTLM related security controls.
