Artifact for: 'Battering RAM: Low-Cost Interposer Attacks on Confidential Computing via Dynamic Memory Aliasing'

This repository contains the archived artifact for 'Battering RAM: Low-Cost Interposer Attacks on Confidential Computing via Dynamic Memory Aliasing.' With Battering RAM, we demonstrate how a low-cost DDR4 interposer can bypass deployed countermeasures to introduce memory aliases, breaking the protections offered by Intel Scalable SGX and AMD SEV-SNP. This artifact includes the hardware designs for the interposer, the firmware for the microcontroller, and proof-of-concept code for all attacks described in our paper.
