Hands-on: Exploit RISC-V CPU using Return-Oriented Programming

Hands-on: Exploit RISC-V CPU using Return-Oriented Programming

In a previous article, I’ve described a step-by-step Return-Oriented Programming (ROP) attack on RISC-V CPU architecture from a theoretical point of view. In this one, I will present a practical attack on a RISC-V CPU deployed on an FPGA. At the end of this article, you will know: * how

Return oriented programming on RISC-V - Part 1

There is a wide spread tendency nowadays to offload computation tasks from CPU to hardware dedicated units that offer better performance in terms of execution time and performance/watt, compared to generic processors. This approach involves the design of new hardware components, in silicon, that outperform the CPUs in tasks

How to generate strong passwords using music theory

I am passionate about music and, in one night, I came up with an idea about how to generate strong passwords that are relatively easy to remember using music theory. In this article I am going to explain the foundations of this method, but firstly, a little background about passwords.
