DeepSec 2023 Talk: Nostalgic Memory – Remembering All the Wins and Losses for Protecting Memory Corruption – Shubham Dubey

Sanna/ August 31, 2023/ Conference/ 0 comments

Memory corruption, a vulnerability that emerged in the 1980s and gained prominence with the discovery of the first buffer overflow in the fingerd Unix application exploited by the Morris worm in 1988, has since become a significant concern in the field of information security. Its prevalence was further underscored by the influential Phrack edition 49 titled “Smashing the Stack for Fun and Profit” in 1996. Today, memory corruption remains one of the most pressing security challenges, compelling the entire defensive security industry to develop robust countermeasures. This session aims to delve into the progress made by the security industry in mitigating and protecting against different types of memory corruption, as well as the current state of these efforts. During the talk, I will explore various techniques that have been introduced worldwide to safeguard against

DeepSec 2019 Training: IoT/Embedded Development – Attack and Defense Lior Yaari

Sanna/ September 19, 2019/ Training

Every developer makes mistakes. If you are unlucky, these mistakes result in a security vulnerability, an almost untraceable bug for the normal developer. Going around the world, helping developers to find and understand the vulnerabilities they’ve accidentally created, we learned that unlike bugs, vulnerabilities are invisible to the eye, mind and UT. No one teaches developers how an attacker thinks, what computers security mechanisms are capable of (and what not), and how to avoid creating possible security mistakes endangering your customers. In this course we will teach you the basics of Embedded Devices security from the beginning: How vulnerabilities are created and how an attacker approaches a new device. From the internals, – physical manipulations, buffer overflows, memory corruptions, timing attacks, all the way to the solution: How to avoid common mistakes and even
