High-Profile Password Database Breaches: A Tale of (Avoidable) Blunders

Over the last few years, password database breaches reported in mainstream press have increased in frequency and magnitude. There is a typical pattern and service providers, such as Adobe or Yahoo or Snapchat, fail on at least two fronts: first, network perimeters and databases are breached and then, improperly secured user data and passwords are exfiltrated and shared in cleartext. Even if the former can't be prevented, there are security best practices to mitigate the impact of the latter, which are (seemingly) ignored.

In this talk, we'll discuss specific case studies and review the essential security best practices for storing sensitive user information. The goal is to show that in every case free, off-the-shelf tools are available, that would have mitigated the scope of the breach and (possibly) the onslaught of negative publicity. As one example, we'll build intuition for why using Scrypt (a memory-hard function) is superior to traditional cryptographic hash functions for storing passwords.
