Date: Fri, 21 Feb 2014 19:18:26 +0000 From: Major Malfunction <majormal@...ate-radio.org> To: bugtraq@...urityfocus.com, dc4420@...420.org Subject: DC4420 - London DEFCON - meeting Tuesday, 25th February 2014 Hi all! We have a busy evening lined up, with two great speakers for you. We will also talk a little about Def Con's Badge Hacking Challenge, and Tony will have some badges with the IO connectors installed. As usual we will be in the downstairs bar at The Phoenix, Cavendish Square, W1G 0PP... The venue is ours from 17:30 until 23:00, talks start 19:30. Entry is free, sorry bar rules are 18+ only. +++ 1st Speaker: Chris Sumner (Suggy), Online Privacy Foundation Title: Predicting Susceptibility to Social Bots Synopsis: Are some Twitter users more naturally predisposed to interacting with social bots and can social bot creators exploit this knowledge to increase the odds of getting a response? Social bots are growing more intelligent, moving beyond simple reposts of boilerplate ad content to attempt to engage with users and then exploit this trust to promote a product or agenda. While much research has focused on how to identify such bots in the process of spam detection, less research has looked at the other side of the question--detecting users likely to be fooled by bots. This talk provides a summary of research and developments in the social bots arms race before sharing results of our experiment examining user susceptibility. We find that a users' Klout score, friends count, and followers count are most predictive of whether a user will interact with a bot, and that the Random Forest algorithm produces the best classifier, when used in conjunction with appropriate feature ranking algorithms. With this knowledge, social bot creators could significantly reduce the chance of targeting users who are unlikely to interact. Users displaying higher levels of extroversion were more likely to interact with our social bots. This may have implications for eLearning based awareness training as users higher in extraversion have been shown to perform better when they have greater control of the learning environment. Overall, these results show promise for helping understand which users are most vulnerable to social bots. +++ 2nd Speaker: Dominic Spill Title: USBProxy - building a cheap and open USB MitM device Synopsis: With the introduction of FaceDancer, there has been a surge of interest in USB security. USBProxy is an open framework for the BeagleBone Black to make it simpler for anyone to monitor, inject or modify data carried over a USB connection. While the FaceDancer will allow devices to be written on a host system, we are able to go further and man-in-the-middle connections to existing devices as well. The BeagleBone Black also enables us to operate at USB 2.0 Hi-Speed +++ Info about DC4420 (Defcon London) - http://www.dc4420.org/ Info about the venue - http://www.phoenixcavendishsquare.co.uk/ Cheers, MM -- "In DEFCON, we have no names..." errr... well, we do... but silly ones...
