May 26th 2015 - REINSTATED!

The train driver strike is cancelled, so DC4420 will go ahead. 1st Talk: Pwning android via nfc/bluetooth Speaker: Adam Laurie, Aperture Labs Ltd (@rfidiot) Synopsis: I've just been given the go-ahead by ZDI/Google to spill the beans on the pwn2own (joint) winning entry in Tokyo last November, in which I pwned Android via NFC & Bluetooth... I'm not going to give too much away before the event, but suffice it to say I pwned Android hard, and he/she/it loved it :) - I will do a live demo, and it will make you install that system update you've been resisting for weeks (if not, don't forget to come and see me after the show so I can follow you at a discreet distance for a few minutes...). This was my first entry in pwn2own (or any such competition for that matter), so I'll talk not only about the hack itself, but also the whole concept of bounties and competitions. I hope this will spark some debate and to turn this into a lively discussion, so if you have a strong opinion on the subject, please come along! Oh, and bring your Android phone... +++ 2nd Talk: An expression of elegance, base 3 math Speaker: Stuart Ward Synopsis: We will explore a forgotten alternative to binary, called balanced ternery. How the maths works and some of the neat things it does.

Talk nights

Format is usually two talks: a primary 1 hour (ish) and, a secondary 30 minutes (ish). Talks start at 19:30, but we have the room from about 18:30 to 23:00.

Speakers Wanted

Typically our programme has a technical talk (~1 hr) and lighter talk (~30 min). Once or twice a year we have a "Lightning Talk" format, with shorter talks up to ~15 minutes, with anyone who wants to speak on the night. The qualifications for speakers are simple, have a subject of interest to fellow technical & InfoSec people. The subject can be on technical or security issues, social interaction with technology, based on the current events, or just something entertaining to our attendees. As a speaker you can be an expert, a student, someone learning a new area, maybe a regular speaker on the conference circuit, but we also love to have new & occasional speakers. Send your talk / activity proposals to talks@dc4420.org You are very welcome to propose running activities other than talks, such as hands-on workshop or an infosec pub quiz, or something else relevant to our techie audience! We also welcome occasional company pitches, to sell or recruit, but to regulate the frequency of these we ask you to buy a round of drinks. Also please discuss with Major Malfunction or Tony beforehand! Previous talks
