There is a super awesome bloodhound-like feature in PingCastle health check reports. It’s called “Control Paths.” It’s really really good. A little clunky and not nearly as verbose as bloodhound, but it gets the job done at finding low hanging fruit. PingCastle has built-in

What if you could confirm password reuse without cracking a single password? In this blog, @Coontzy1 shows how hash shucking leverages NTLM hashes to identify reuse across Kerbereros, NTLM, and cached credentials - and how to defend against it. Read now! https://t.co/zdAwSSo0LB

Let me blow your mind real quick: When you use Remote Desktop (RDP), Windows secretly takes screenshots of what you are doing. It’s called the RDP Bitmap Cache. To make the connection faster, Windows saves small tiles (images) of the remote screen to your hard drive in a bin

PSA now that Cloud PKI is included in E5 If you did a trial of Cloud PKI, please don't use the old setup Tear it all down and rebuild to ensure you are using proper keys backed by a hardware security module (HSM) There is no migration path: https://t.co/ohL9IeZ5Bb

I'm really excited about this announcement. The Intune Suite is now included in #Microsoft 365 E3 and E5! Crucially, organizations with E3/E5 now have access to #CloudPKI for Intune! Time to replace those certificate connectors!! :) #mdm #msintune #security #pki

This is very true. If, say, you have per-device local admin accounts but only need to use them when sitting in front of machines (or, conversely, only need to use them via RDP) please, please enforce that.

Always keep in mind that literally any form of MFA/2FA/2SA or cryptographic authentication takes basic password attacks off the table. (Including use of password spraying, bruteforcing, cred stuffing, abuse of passwords captured by info stealers, etc.) Which is a big deal.

We spend a lot of time talking about OAuth phishing, token theft from malware, adversary in the middle phishing and other novel attacks, and rightly so, but it is important to remember that MFA is still an extremely valuable control. Modern MFA reduces the risk of identity
