I can't believe am getting this quality content for free from youtube

[PixelSergey]

After a ton of incomprehensible tutorials, this made it click. Thanks!

[Hacker_Baby]

Bro, this just made my OSCP journey SO much clearer! Thank you so much!! Phenomenal video!

[TheBlackJames]

I'm late to the party, but this video is a gem and saved me many headaches! Thank you so much for the great content!

[anthonya]

You are exceptional at explaining complex topics. Please consider making videos on SAML, OAuth2, OpenId etc.

[enisibro]

THANK YOU!

this is BY FAR the best explanation ive found. it is so good that im writing my first comment ever on YT bc it helped me a lot!

[rafsterable]

VB what you offers is pure quality ... whenever I find it difficult to understand something that is quite technical about kerberos I return to your videos. you are amazing

[TheRonTait]

Finally a video that has a pcap example along with it. Nicely done mate.

[jacklee]

This is one of the best explanation regarding the Kerberos auth, and the process of TGT.

Thank you for the Clear Explanation 🙏🙏, one of the best video on Kerberos authentication and practical demonstration through pcap

[abdulaleem]

I have yet to see a better explanation than this! (Although I am not searching for it because there cannot be a better explanation than this). Great Work. God bless you

[TechChefMM]

Absolutely FANTASTIC Kerberos explanation, diagrams, AND demo! Kudos to you! I've already watched it twice. MM

[rlejeune]

Your three-tiered approach proved to be very effective in helping me grasp the info. First time viewing one of your videos. I'm subscribed and think I'll be spending significant time in your presentations. Thanks.

[spicyburglar]

Damn, the Wireshark part was really helpful. I wish I could give more than a like because of the effort you put into this, specifically talking about the script you made for demo purposes. Subbed!

[cybrflash]

@VbScrub - this is the single BEST in-depth explanation and deep dive into Kerberos I've ever seen, and I've read (and watched) **all of them**. I've read the MIT documentation, the Windows & Microsoft documentation, many other Blogs and Guides and videos, and you have single-handedly outclassed them all.

Kerberos is an incredibly complex and confusing topic (largely due to the authors of the protocol) that you have broken down and explained step by step of the 5 W's (Where, When, Why, hoW and Who) of modern Kerberos. Thank you so much! Subscribed!

[bonesseben]

best video on kerberos stuff that ive found - THX

[kelso]

Dude thank you so much. I spent hours trying to understand this process. I felt like I had almost all the parts except a couple steps weren't clicking for me. You made those click. Cheers!

[slythx]

You explained the topics very clearly not only for this video but to all of your videos. I hope you come back and create more videos again, thank you!

[anupthakare]

Really helped understand the request flow diagram in Kerberos authentication. You have explained the complex looking concepts in a very simplified manner. Kudos! Keep up the great work!

[julianjung]

This was the best explanation I found by far. Thank you.
