A Brief Analysis of Hyperjacking Attacks in Virtualized Environments

In September 2022, security researchers discovered a rare new type of attack method known as Hyperjacking. Attackers deployed an infection implant within VMware virtualization software to control the infected virtual machine systems and evade detection. It is important to emphasize that the danger of this attack lies not in exploiting external remote code execution vulnerabilities, … Read more

ARMv8/v9-GIC Virtual Interrupt Direct Injection System Architecture

ver0.2 Introduction In the previous article, we introduced the basic architecture and routing mechanism of LPI-type interrupts. I believe everyone is now somewhat familiar with LPI-type interrupts, at least understanding the difference between bus-based (Message) and hardwired (Signal) interrupt types. We also discussed the basic architecture and working principles of GIC physical interrupt virtualization. However, … Read more
