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.

Securing Password Storage - Increasing Resistance to Brute Force Attacks

In this talk Tiago Teles takes apart password protection scheme analyzing the attack resistance of hashes, hmacs, adaptive hashes (such as script), and encryption schemes. First, we present a threat model for password storage. Then audience members will learn the construction, performance, and protective properties of these primitives. Discussion of the primitives will be from a critical perspective modeled as an iterative secure design session. Ultimately, this session presents the solution and code donated as part of the on- going OWASP PSM (password storage module) project. Discussion of this solution will include key techniques for hardening PSM learned through years of delivering production JavaEE code to customers...
