Neutralizing Peer-to-Peer Botnets

This presentation is a case study on our takedown efforts against state-of-the-art peer-to-peer botnets. Unlike conventional botnets, peer-to-peer botnets are decentralized, and thus cannot be disabled by neutralizing centralized control facilities. Takedowns against peer-to-peer botnets require a highly decentralized approach targeting the infected drones themselves. We describe the technical and ethical challenges we faced in our own takedown attempts.

Discovering flaws using JS-Enabled crawlers

Automated testing of security faults on a web page is common practice these days. However, most modern web application aren't a set of pages anymore. They load their content dynamically using AJAX and tailor the results to the user's needs using JavaScript. Running the automated tools on these applications is much harder, if not impossible. Using Crawljax, a JavaScript enabled Crawler, testing all pages and states of such web applications becomes possible again. In this presentation, I will give an overview of the possibilities Crawljax offers.

Next to that, he is also interested in advanced malware, particularly in the resilience of peer-to-peer botnets.
