Cold Boot Attack You Can Do With A Pi

A chilly boot assault is a method to extract RAM contents from a working system by energy biking it and studying out RAM instantly after loading your individual OS. How straightforward is it so that you can carry out such an assault? As [anfractuosity] reveals, you possibly can perform a cold boot attack with a Raspberry Pi, with a fairly easy {hardware} setup and a hefty chunk of bare-metal code.

[anfractuosity]’s setup is straightforward sufficient. The Pi 4 below assault is ready as much as boot from USB drive, and a relay board has it swap between two doable USB drives as well from: one with a program that fills RAM with , and one other with a program that extracts RAM out by means of UART. The method is managed by one other Pi controlling the relays by means of GPIOs, that additionally screens the goal Pi’s UART and makes use of it as a channel to extract reminiscence.

The outcomes are fairly spectacular. After 0.75s of power-down, many of the picture might be extracted. That’s with none cooling, so abusing a can of electronics duster is probably going to enhance these outcomes dramatically. Wish to play with chilly boot assaults? [anfractuosity]’s code is nice for getting your toes moist. Moreover, the code examples supplied function a beautiful playground for basic reminiscence assault analysis.

Raspberry Pi not enjoyable sufficient for you anymore? Nicely then, you possibly can all the time start playing with Android phones!
