Information security, on the other hand, is the team that is constantly preventing the business from freely doing as they please. IT is...

This post is one in a series of posts describing TLS CBC padding oracles I have identified on popular web sites. The other posts in this series include an overview of CBC padding oracles, a walkthrough of how I came to develop a new CBC padding oracle scanner, and a write-up on the GOLDENDOODLE attack. Although not POODLE per se, Zombie POODLE is in...

*UPDATE: Padcheck source is now available on GitHub: https://github.com/Tripwire/padcheck* Since August, I’ve spent countless hours studying CBC padding oracle attacks toward the development of a new scan tool called padcheck.
