2/2 1st conf day @ Troopers 2025, for the evening I had signed up for some story telling. “Once upon a time when I fixed an AD domain that had self-detonated!” @WEareTROOPERS
1/2 1st conf day @ Troopers 2025, in AD/EntraID sec track, delivered my session “Demystifying (M)SAs: Unveiling Best Practices And Security Measures To Reduce Risk And Impact”. Shortly after start room filled up completely. HONORED to have lots of people attending & ask questions

!!! PATCH PATCH PATCH !!! Yet another vulnerability where it’s very important 2 keep up with patching. Not able 2 patch? => Review membership of “Network Configuration Operators” security group, restrict membership & monitor membership changes Details: cybersecuritynews.com/poc-exploit-ac…
Still testing….. due 2 huge amounts of KrbTGT accounts & trials I found issue that required fixes. Retrying again. It looks very promising! Almost done processing 10000+ KrbTGT accounts through Pwd Reset Routing. Have 2 let it run 2 see whole process complete over nr of days! 👌
3/3 - KRBTGT RESET SCRIPT Of course not enough. While this is being tested, in other AD forest, as we speak pre-creating 10000+ RODCs to get same amount of KrbTGT accounts. I just want to see what blows up first! 1) the script?, 2) the VM(s)?, 3) the host? Place your bets! 😁
2/3 - KRBTGT RESET SCRIPT Want to test with some large number of accounts. Pre-created 500+ RODCs & with that got same amount of KrbTGT accounts. It looks very promising!
1/3 - KRBTGT RESET SCRIPT Testing KrbTGT reset script with focus on Password Reset Routing having very tight intervals (3 days for first & 1 day for second). Works like magic. Really exciting seeing this work.
Do you have lots of domains or lots of RODCs in an AD domain? Would you like to reset the pwd of ALL KRBTGT accounts in controlled & automated manner following certain schedule & interval to combat against Golden Ticket attacks? That’s coming, stay tuned! #BeSecure #StaySecure
Finished coding the new/updated version of the "Reset-KrbTgt-Password-For-RWDCs-And-RODCs" script. Packed with new improvements and additional options for automation. Next step > TESTING! If you are willing to test in your (large) test environment, just let me know!
