One hacker, @archangel, took a different approach at H1-305. Typically, @archangel is heavily involved in collaboration during live hacking events, but he decided to take this one solo. His hard work and effort paid off, earning him not only first place but also the title of the event’s Most Valuable Hacker. 

Congratulations to @archangel and the other winners of H1-305!

“One of the noteworthy lessons learned for all security teams from this live hacking event was the inclusion of software and engineering teams from Capital One. It was exciting and powerful to observe the benefits of the live collaboration between Capital One engineering teams and the hacker community. The ability for engineers and hackers to ask live questions of each other created unique opportunities for learning and working together.”

— Alex Rice, CTO, HackerOne


Alongside hours of exciting hacking, hackers and the Capital One team enjoyed the beautiful Miami weather, food, and arts scene. At the Wynwood Walls museum, featuring hundreds of artists from over 20 countries, hackers were able to test their own artistic abilities by spray painting during the interactive portion of the museum. With delicious food trucks and great weather, it was a fun opportunity for everyone to explore Miami!
