DeepSec 2019 Talk: Abusing Google Play Billing for Fun and Unlimited Credits! – Guillaume Lopes

Sanna/ November 22, 2019/ Conference, Security

In 2017, the estimated global in-app purchase revenue was projected to exceed $37 billion. Just in the Google Play Store, for 2018, more than 200 000 apps are offering in-app purchases. However, the Google Play Billing API is vulnerable by design and allows an attacker to bypass the payment process. I analyzed several android games and found that it’s possible to bypass the payment process. This presentation will show real vulnerable applications (Fruit Ninja, Doodle Jump, etc.). We asked Guillaume a few more questions about his talk. Please tell us the top 5 facts about your talk. The vulnerability presented is really easy to exploit Client side issues are not dead in 2019! It seems nobody cares about losing money in the game industry… Very few vendors fixed their implementation Real vulnerable applications will

DeepSec2019 Talk: SD-WAN Secure Communications Design and Vulnerabilities – Denis Kolegov

Sanna/ September 2, 2019/ Conference, Security

Hardening communication protocols against network attacks is hard. And yet a lot of products are available on the market that allow you to transport data and messages. Since virtualisation entered the world of technology all things software-definded (SD) have become popular. Denis Kolegov will explain at DeepSec 2019 what the state of affairs in terms of information security is. The SD-WAN New Hope project targets the security of SD-WAN (software defined wide area network) products. It was started in December 2017, when a customer decided to buy a very secure and well-known SD-WAN product from one of the Top 5 vendors and wanted us to perform threat modelling and a vulnerability assessment. We were doing that for 6 months and found out that the product was awful from a security perspective. It had multiple

ROOTS 2018: How Android’s UI Security is Undermined by Accessibility – Anatoli Kalysch

Sanna/ November 9, 2018/ Conference, ROOTS

Android’s accessibility API was designed to assist users with disabilities, or temporarily preoccupied users unable to interact with a device, e.g., while driving a car. Nowadays, many Android apps rely on the accessibility API for other purposes, including apps like password managers but also malware. From a security perspective, the accessibility API is precarious as it undermines an otherwise strong principle of sandboxing in Android that separates apps. By means of an accessibility service, apps can interact with the UI elements of another app, including reading from its screen and writing to its text fields. As a consequence, design shortcomings in the accessibility API and other UI features such as overlays have grave security implications. This talk will provide a critical perspective on the current state of Android accessibility and selected UI security features.

DeepSec 2018 Talk: Uncovering Vulnerabilities in Secure Coding Guidelines – Fernando Arnaboldi

Sanna/ October 3, 2018/ Conference, Security

Several government-related and private organizations provide guidance on how to improve the security of existing software as well as best practices for developing new code. These organizations include the Computer Emergency Readiness Team (CERT) Secure Coding Standards, Common Weakness Enumeration (CWE), Open Web Application Security Project (OWASP), and National Institute of Standards and Technology (NIST) Software Assurance Metrics. Fernando’s talk will expose multiple underlying exploitable vulnerabilities in the secure code that follows the recommendations from each of these organizations. Even though these guidelines were created to improve software security, they may also inject side vulnerabilities due to a lack of proper analysis. Within secure code snippets, reviewed by many and considered trustworthy by all, are issues that attackers could exploit to escape secure directories, abuse insecure hashing and encryption practices, or even expose applications

DeepSec 2018 Talk: Global Deep Scans – Measuring Vulnerability Levels across Organizations, Industries, and Countries – Luca Melette & Fabian Bräunlein

Sanna/ September 25, 2018/ Conference, Internet, Security

Metrics are plentiful, but they are hard to come by when it comes to meaningful numbers. This is why we were amazed by the submission of Luca Melette and Fabian Bräunlein. Why? This is why: “We introduce global deep scans that provide insights into the security hygiene of all organizations exposed to the Internet. Our presentation discusses vulnerability levels across different groups of organizations and points out differences in the underlying maintenance processes. We find that different industries have a lot to learn from each other and provide the necessary measurements to start these dialogues.” We asked Luca and Fabian a few more questions about their talk. Please tell us the top 5 facts about your talk. 1. Come 2. Watch 3. Our 4. Talk 5. You’ll see results from a global vulnerability scan

DeepSec 2018 Talk: Injecting Security Controls into Software Applications – Katy Anton

Sanna/ September 20, 2018/ Conference, Security

“SQL Injection was first mentioned in a 1998 article in Phrack Magazine. Twenty years later, injection is still a common occurrence in software applications (No.1 in latest OWASP Top 10 2017). For the last 20 years, we have been focusing on vulnerabilities from an attacker’s point of view and SQL injection is still King. Something else must be done.”, says Katy Anton. “What if there is another way to look at software vulnerabilities? Can vulnerabilities be decomposed into security controls familiar to developers? Which security controls are an absolute must-have, and which additional security measures do you need to take into account? These are hard questions as evidenced by the numerous insecure applications we still have today. Attend this talk to explore security vulnerabilities from a different angle. As part of this talk, we

DeepSec2016 Talk: Of Mice and Keyboards: On the Security of Modern Wireless Desktop Sets – Gerhard Klostermeier

Sanna/ November 3, 2016/ Conference, Internet, Security

Wireless desktop sets have become more popular and more widespread in the last couple of years. From an attacker’s perspective, these radio-based devices represent an attractive target both allowing to take control of a computer system and to gain knowledge of sensitive data like passwords. Wireless transmissions offer attackers a big advantage: you don’t have to be around to attack something or someone. Plus the victims often don’t know what it happening. At DeepSec 2016 Gerhard Klostermeier will present the results of research on the matter of wireless mouse/keyboard attacks. Furthermore you he will demonstrate ways in which modern wireless desktop sets of several manufacturers can be attacked by practically exploiting different security vulnerabilities. We recommend this talk to anyone still using old-fashioned input devices for creating content. Gerhard is interested in all things
