The SQL Server Crypto Detour

One of the things that I love about my role at SpecterOps is getting to dig into various technologies and seeing the resulting research being used in real-time. This post will explore one such story of how I was able to go from a simple request of recovering credentials from a database backup, to reverse engineering how SQL Server encryption works, finding some new methods of brute-forcing database encryption keys.. and finally identifying a mistake in ManageEngine’s ADSelfService product which allows encrypted database backups to reveal privileged credentials....

There are some caveats introduced with later versions of macOS which we will explore, but in this post we’ll look at a vulnerability in macOS Sonoma which has been around for a long time, and remains an 0day, urm, to this day....
