Troy, for those of you that don't know is one of the world's most widely known web security experts. He famously created Have I Been Pwned?, a site where you can check whether your personal information has been compromised in data breaches.
How did this happen?
In a happy coincidence, I saw him tweet he had some time available for private workshops in Oslo around NDC.
I thought "what the heck", and posted it to our company's security-channel on Slack.
I also forwarded it to my closest managers, but didn't think any more of it.
Then it came up again; People were interested to know if any contact had been established.
Andreas (one of my closest managers) said that they were in communication.
Next thing I know, there's an announcement and a thank-you.
Troy would be paying us a visit, holding a two day internal workshop. And that's basically how it went down.
During the workshop, we used offensive techniques to illustrate damage potential (attacking a purpously insecure web application, etc.) and learned how to make our solutions are secure and protected.
I had the privilege of being Troy's chaperone, which basically meant I walked him to his city bike and made sure he got lunch.
All in all, it was a fun, educational experience!
