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 (http://www.sectalks.org/perth/) and quickly spread to Sydney (http://www.meetup.com/sectalks/), Melbourne (http://www.meetup.com/SecTalks-Melbourne/), and Brisbane (http://www.meetup.com/SecTalks-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 (https://github.com/sectalks/sectalks/blob/master/ctf-solutions/0x00/matt/solution.txt)) to ... very interesting. All our talks, CTFs and solutions are written up and published on GitHub (https://github.com/sectalks/sectalks).

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.

Hey SecTalks! from March 2020 we'll be hosting our events online - at least until we're all able to buy toilet paper again. For now, this will consist of a capture the flag challenge hosted on Slack. You will need to be ready with the following: • Membership in our Slack channel. To obtain this, you'll need an invite: send me (Patrick) a *private* message on meetup with your email address and the solution to this encrypted phrase: fvb hyl sprlsf av il lhalu if h nybl. • Your laptop, for hacking • Some beer or cider to drink while hacking at home, if you like to drink beer or cider while hacking at home • You'll probably end up writing a little bit of code, so make sure your favourite compiler and/or scripting language is set up. Or vim. Once you have a login, at the appropriate time (6:30pm on Thursday, don't get it wrong!) join the Slack channel #sectalks_lon in Sectalks Slack and instructions will be posted. You can also join the slack channel at other times, it's filled with fun people. ***Make sure you're able to log in to Slack before the event, and request an invite per above if you can't!*** Don't forget, the winner this month gets to write the virtual CTF for next month! Woo! Virtual CTF! There's usually a bit of collaboration, so don't worry about having to solve this all yourself - we'll keep an active This will be an online meetup. Don't go to Cisco's office, security will be very confused. 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.
