Today I had the pleasure of presenting my research at #BHEU, and I am now very excited to share it with the rest of the world. TL;DR - unauthenticated attackers can spoof sensitive DNS records by abusing Microsoft DHCP. @akamai_research 1/7

Part 2 of our DACL abuse attack/detections is live! This time @mega_spl0it and myself explore various attributes that can be modified with @kevin_robertson’s PowerMAD tool.

Recording of the talk is up: youtu.be/QSRxrTXj8G0 This was my first public talk, so yes I don't know how to use a handheld microphone. :)
Slides from our Active Directory & DNS (ADIDNS) talk at BSidesCharm 2023 are up. AD & DNS: A Match Made in Heck I believe video will be released soon(ish).

[BLOG] Attacking and Remediating Excessive Network Share Permissions in Active Directory Environments netspi.com/blog/technical… #NetSPI #PowerShellAllTheThings
Here's another serious vulnerability to add onto the list of recent Azure issues. This is our write up (and a thread) on CVE-2021-42306 (CredManifest), which addresses the cleartext storage of App Registration credentials in AAD SP manifests. netspi.com/blog/technical… (1/5)
New blog just went live. It walks through the details of a new Azure attack that I've dubbed "API Connection Hijacking", plus some tips on where to find creds in Logic Apps. netspi.com/blog/technical…
About a year ago, @asegunlolu reached out about being a co-author on an Azure pentesting book. We are currently wrapping up the final chapters and the book is now available for pre-order on Amazon - amazon.com/Penetration-Te…
Lot's of new updates to Tokenvator! Check out the related blog by @0xbadjuju on the @NetSPI blog - netspi.com/blog/technical…
More amazing research from @jakekarnes42 around alternative ways to execute commands on Azure VMs. I think the persistence options (see the examples at the end) are going to be a great way to maintain access on an Azure VM - netspi.com/blog/technical…
Training Announcement - @NetSPI's first public course of the "Dark Side Ops: Azure Cloud" training will be this August 23-24. This will be a virtual training, but we hope to do an in person training in the near future. Tickets and course information here - netspi.com/training/dark-…
MitM Tip: The Windows 10 WebDAV client verifies certs when connecting with a FQDN or IP address but not a hostname (\\host@SSL\share). For now, MS will not be patching this issue. Bonus Tip: By default, WebDAV basic auth is enabled over SSL only so cleartext creds can be exposed.
Is anyone still seeing wpad resolved through LLMNR/mDNS with chrome/edge? My Windows 10 lab systems are trying to resolve through DNS only now. It may be related to this bugs.chromium.org/p/chromium/iss…
Wooho, just got local PTH for an interactive shell working! All other PTH tools can only be used for network auth. as far as I can tell. I used a modified Invoke-SMBExec from @kevin_robertson and a modified RoguePotato from @splinter_code and @decoder_it. Blog post will follow!
All the details for CVE-2020-17049 are now available! The overview contains a summary of the vulnerability and its exploit, including links to 2 deep dive posts which cover much more. blog.netspi.com/cve-2020-17049…
I'm super excited about this post finally going live, but here is some fantastic Kerberos research by @NetSPI 's @jakekarnes42! This link is the intro post, but additional links are there for the two deep dive follow up posts on CVE-2020-17049. blog.netspi.com/cve-2020-17049…
I'm excited to share that CVE-2020-17049 has been issued for a vulnerability that I found. There are more details to come, but I'll be holding off publishing for now while the patchwork is still ongoing. msrc.microsoft.com/update-guide/v…
