DeepSec 2023 Talk: The Evolution of Linux Binary Exploitation: From Outdated Techniques to Sophisticated Modern Attacks – Ofri Ouzan & Yotam Perkal

Sanna/ September 28, 2023/ Conference/ 0 comments

In the ever-evolving realm of cybersecurity, the cat-and-mouse game between attackers and defenders continues to intensify. To safeguard critical systems against malicious exploitation, the hardening of binary files has emerged as a fundamental security measure. However, no security measure remains impervious to threats, and binary hardening techniques face ongoing challenges. This talk aims to shed light on the significance of binary hardening as a countermeasure against growing vulnerabilities. Through a comprehensive examination, we explore both traditional and contemporary binary exploitation techniques, providing real-world insights into modern exploiting methodologies that bypass protective mechanisms implemented through binary hardening. Our research addresses the lack of accurate and complete sources of information on binary hardening, emphasizing the importance of understanding ELF file structure and attacker avoidance strategies. By encouraging vigilance among developers and defenders, we aim to raise
