MITRE Corporation’s ATT&CK framework is a living, curated repository of adversarial tactics and techniques based on observations from actual attacks on enterprise networks. It’s a valuable trove of information for security analysts, threat hunters and incident response teams. Today, I’m going to look at a particular method for evading detection, often...

Vulnerability Management is a much-talked-about practice in the IT security industry. Whether it is the debate on vulnerability scoring, how to implement a suitable vulnerability management program based on your own resources or even trying to convince leadership a vulnerability management solution alone won't solve all your cybersecurity issues,...

Organizations have slowly realized they need to spend on IT to enable their businesses. Information security, on the other hand, is the team that is constantly preventing the business from freely doing as they please. IT is seen...

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.
