Wow this was very educative! Thanks for taking your time and explaining the email headers for the public.
I demand more quality content like this! As someone getting into cyber security I appreciate the detailed well-thought-out content that you provide. Thanks!
I definitely plan to keep rolling out more and more, the only thing holding me back is time to get them done. Check out my Blueprint podcast available on all major platforms for a bunch of extra stuff that will help you on your journey in cyber security, and best of luck out there! :)

Hey, thank you so much for creating this video and video series.
I'm a new start in the cyber security industry, and this has been so freaking helpful for my email analysis workflow.
I feel much more confident in my decision making when it comes to confirming/denying release requests emails to users.
Thank you, John.
John, thank you so much for creating this content. I know it must be hard to keep pushing forward this content, but please know this has been INVALUABLE to people like myself.
Wth… I have been searching cyber security resources to learn from on TH-cam for 1yr and 1 month now and just now I finally find you channel… so mad.. you post really good content I’m pissed I’ve been missing out..
WOW just wow
Quality content
Really appreciate your effort please keep it up.
Clear, concise and to the point. I'm really looking forward to viewing your lecture courses over at SANS!
You deserve more views and subscriptions. Awesome videos!
Very good explanation! Well done John!
Excellent ! I really enjoyed this one
Awesome explanation. Thanks John!
Thank you John, great explanation!
Amazing shit my friend
Thank you john
Great Video. Thanks
Great tutorial John, is there away I can dig a little deeper on this subject or do you have more videos on this. I have taken a number of SANS courses, but need more of this topic, as I encounter phishing daily. Thanks
Amazing video
Impressed :)
Great video! Useful concepts and tools, it helped me to understand better some concepts about mail headers. One question John, how dangerous is clicking on a potential phish link? I feel like most of the times the best way to determine if a mail is malicious is analyzing the content of the links (in a VM), and I always thought that just clicking on a url would need a browser vulnerability or something rare to cause harm, but I'm never sure.
Hi, what is the name of the plug in you installed that is parsing out the eml file, thanks
Nice video
Hi John,
Thank you for sharing this.
We can also use header analyzers available like from Google, ryt?
Hello. Would you be able to look at an email and help figure out if it is spoofed? TIA
hey could you help me with analyze spoofed email that occurred in our organization.
what is the name of the plug in you installed that is parsing out the eml file, thanks
I'm also interested in the plugin you were using please. And BTW thanks for your videos, as always clear and straight forward.
SANS courses are way to expensive to afford...:((
