Microsoft is rolling out a new security default for Windows 11 that will go a long way to preventing ransomware attacks that begin with password-guessing attacks and compromised credentials.


The new account security default on account credentials should help thwart ransomware attacks that are initiated after using compromised credentials or brute-force password attacks to access remote desktop protocol (RDP) endpoints, which are often exposed on the internet.


The new feature is rolling out to Windows 11 in a recent Insider test build, but the feature is also being backported to Windows 10 desktop and server, according to Dave Weston, vice president of OS Security and Enterprise at Microsoft.


That’s big news and is a parallel to Microsoft’s default block on internet macros in Office on Windows devices, which is also a major avenue for malware attacks on Windows systems through email attachments and links.
