Capture The Flag
There’s a Capture The Flag security challenge going on, organized by Stripe, the payment company. Capture The Flag security challenge are a series of technical weaknesses that participants need to find in order to find flags and capture them for points. It can range from finding a password through a SQL injection, to getting permissions to a server box.
I highly recommend anyone that is interested in broadening their development skills in joining those challenges. Stripe-CTF was centered about web security, and played with Python, Ruby, PHP and others. Learned quite a bit. Padding attack, anyone?
