Next Meetup

SecTalks LON monthly meetup (Level 2, WeWork, 15 Bishopsgate)
This month, we'll be having a few beers, solving a CTF, and talking about InfoSec. Like we do _every_ month. You'll need to bring: • Your laptop, for hacking • If you'd like, some beer or cider to share For this CTF, you'll need the following on your laptop: • You'll probably end up writing a little bit of code, so bring your favourite compiler and/or scripting language. Or just solve the whole thing with vim macros. Don't forget, the winner this month gets to write the CTF for next month! Woo! CTF! There's usually a bit of collaboration, so don't worry about having to solve this all yourself; team up with someone and learn some new skills(z). The venue is Cisco Meraki, Level 2, 15 Bishopsgate EC2N 3AR (WeWork building). The closest station is Bank. Meet at 6:30pm. Building security is pretty tight, so make sure you RSVP with your real name - we'll give that to the front desk so they know you're coming. New to InfoSec? Not a problem. While coding skills are recommended, we encourage people to work together and to share their solutions to the problem each month.

What we're about

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 August 2016, we'll be running London meetups in a couple of formats:

• Ninja Nights: we meet at a pub and show off our ninja skills while solving a short 60-minute CTF. And drinking.

• 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).

SecTalks started in 2013 in Perth, Western Australia ( and quickly spread to Sydney (, Melbourne (, and Brisbane ( - and now we're working to kick off our first international meetup in London. We're a zero-cost operation, run by members: we present our talks in donated space, CTFs are written by the winners of the previous month, and we encourage everyone to speak occasionally on something cool they're working on.

Sound like fun? Hit Join above. New to infosec? Hit Join above! We're open to anyone who wants to improve and share their skills, and our CTF challenges range from straightforward (for example, an insecure web application ( to ... very interesting. All our talks, CTFs and solutions are written up and published on GitHub (

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 ( - 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.
