There are still some seats open for this training. Come join me in a couple weeks for some cloud hacking. This is a fully remote 4 day (16 hours total) class for $395. Also, each day is recorded so you can view it at your leisure.
I'm stoked to be teaching my Breaching the Cloud course again November 2-5 as part of Secure West Virginia. A training ticket also gets you access to the rest of the Secure WV conference. June & August classes sold out quickly so sign up soon here: https://t.co/aZJKm1Y08D

Notice to vendors: Next week if your sales dweebs tell me you use deep learning, AI, or machine learning at #RSAC but won't explain how, I'm live tweeting all the fail with hashtag #VendorWordVomit. Naming and shaming. You've been warned.

Fixed an issue with the Password Filter deployment in CredDefense so it /should/ be good now if you run CredDefense.exe that's in the "Builds" folder. Next up is cleaning up the whole build process. https://t.co/GUv1BaYh1G.

If you aren't looking for Lync servers, you should be! All of the benefits of attacking OWA portals (user enum, password spray, domain info,etc.). There's a good chance one is present and an even better chance that it's been forgotten. Check out this post: https://t.co/gjWUKLkn2V
