Encryption is one of our favourite topics. This blog and our events feature discussions, tools, and content regarding cryptography. The first DeepSec conference in 2007 even had a presentation about a practical attack on GSM’s A5/1 algorithm. Subsequent conferences followed up on this, for example, the state of affairs of…

The world is much easier to handle without limits. If you have all your frameworks freely available and have the luxury of running your code with a multi-MB (or -GB) runtime environment, then you are in paradise. The world of embedded devices and the Internet of Things looks different. Saving…

The recent vulnerability in the Microsoft® Exchange server application has sparked many discussions. One of the topics is connected to the skills of IT departments responsible for patching systems in time. How can n weeks or months pass until upgrades are rolled out and in place? Well, the answer is…

In theory, there is the evolution from bug over to weakness, vulnerability and finally the exploit. Errors in code and application behaviour are interesting for any serious developer. Security researchers also look for bugs and ways to make code do something it wasn’t designed for. In the absence of critical…

When one talks about digitization, one usually means networked control and measurement systems. The associated technical term Industrial Control Systems (ICS) covers a wide area and extends into Industry 4.0, in which information security plays a very important role. The right design and secure code thus become part of critical…

The Art of the Breach is designed to be a journey for anyone interested in physical security. Robert takes the audience on a trip from the public sidewalk outside a target organization all the way through to the executive filing cabinet in the President’s office. While many physical security talks…

This will be one of the few online talks held at DeepSec. Dr. Nestori Syynimaa covers the wonderful world of Azure AD and third-party code. Azure AD is used by Microsoft Office 365 and over 2900 third-party apps. Although Azure AD is commonly regarded as secure, there are serious vulnerabilities…

Content Security Policy (CSP) is the number one defensive technology in modern web applications. A good CSP offers a lot of possibilities…
