Presentations

Securing Password Storage - Increasing Resistance to Brute Force Attacks

By Tiago Teles.

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...

Neutralizing Peer-to-Peer Botnets

By Dennis Andriesse.

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.
