Meltdown Attack Lab Launching attack to exploit the Meltdown vulnerability in Intel CPUs. This lab works on SEED Ubuntu 16.04 VM, but only partially works on the Ubuntu 20.04 VM. Spectre Attack Lab Launching attack to exploit the Spectre vulnerability in Intel CPUs.

However, after adding printf("something\n") before calling spectreAttack(larger_x) (in both SpectreAttack.c and SpectreAttackImproved.c), the Spectre attack became successful. Not sure why. I guess this is a race condition problem, so the timing matters. That extra printf statement might have got the timing correct. On Ubuntu 16.04, there is no need for this extra printf statement. The attack works quite consistently on standalone SEED VM and cloud VM.

The Meltdown vulnerability represents a special genre of vulnerabilities in the design of CPUs. Along with the Spectre vulnerability, they provide an invaluable lesson for security education. The learning objective of this lab is for students to gain first-hand experiences on the Meltdown attack.

September 12, 2022 - In the lab you read a block of memory that you shouldn't be able to access. By reading the code snippets in the pdf you can get a pretty good understanding for the attack. Actually completing the lab takes about an hour, and I thought it was pretty neat. SEEDS Main Page · Spectre Lab Files ·
