hashcat is currently the only viable tool for auditing SQL Server 2025 login passwords.

The results show how #PBKDF2 slows down brute-force attacks both inside and outside of SQL Server compared to the pre-2025 hashing algorithm.

Full methodology, benchmarks, and code included.

I've noticed today that Microsoft Bing Webmaster Tools has a new "AI Performance" tab.
Apparently, my SSMS 22 config blog post has been cited by "Microsoft Copilots and Partners" a total of 284.7K times since I've published it ~6 months ago. Pretty neat, although this doesn't really translate into visits.
