Route to Safety: Navigating Router Pitfalls

18 March 2024 at 00:00
Introduction Wi-Fi routers have always been an attractive target for attackers. When taken over, an attacker may gain access to a victim’s internal network or sensitive data. Additionally, there has been an ongoing trend of attackers continually incorporating new router exploits into their arsenal for use in botnets, such as the Mirai Botnet. Consumer grade devices are especially attractive to attackers, due to many security flaws in them. Devices with lower security often contain multiple bugs that attackers can exploit easily, rendering them vulnerable targets.

Introduction The prevalence of memory corruption bugs persists, posing a persistent challenge for exploitation. This increased difficulty arises from advancements in defensive mechanisms and the escalating complexity of software systems. While a basic proof of concept often suffices for bug patching, the development of a functional exploit capable of bypassing existing countermeasures provides valuable insights into the capabilities of advanced threat actors. This holds particularly true for the scrutinized driver, cldflt.
