h1-415 CTF Winners Announced!
Hello hackers!
Thanks to all of you who participated in our #h1415 CTF! We had a lot of fun building it, and it looks like many of you had a great time participating. As promised, our two winners will be sent to San Francisco for our live hacking event, h1-415! The first five participants who found the flag and submitted a valid write-up will receive a care package including a HackerOne hoodie!
On January 15 at approximately 13:37 PM, our co-founder, Jobert Abma lost access to his account, so we asked our community of hackers to give us a hand in recovering our top-secret documents. Here’s how it went down:
