SecTalks are informal, technical, no-bullshit* IT security discussions. It's about learning from others, talking about interesting things you're working on, and improving your security skills. We run a regular CTF.
From July 2018, we'll be running Berlin meetups in a couple of formats:
• Talk & CTF: a 15-25 minute presentation on an infosec topic, followed by a short 60-minute CTF. The winners write the next CTF (and show off their solutions).
• CTF-only: A longer 80-minute CTF. The winners write the next CTF (and show off their solutions).
Working on something interesting? Proposals for 15-25 minute presentations to get us started are extremely welcome. As in, I will shower you in gratitude and/or beer.
What on earth is a CTF? Each month, a member writes a Capture-the-Flag ( https://en.wikipedia.org/wiki/Capture_the_flag#Computer_security ) - a technical puzzle - for other members to solve. At the next meeting, the winners present their solution, and the first person to solve the CTF writes the challenge for the next month. Topics include things like binary reverse engineering, breaking simple crypto, or analysing network services. Generally, no prior knowledge is expected - the challenges are sometimes obscure, and you're expected to do a little bit of research to figure it out.
