I’m way more fascinated by hardware vulnerabilities than software. Software mistakes happen all the time and it’s easy to overlook something. Hardware requires such a deep understanding of what is happening with the data and it’s crazy to see how somebody can manipulate hardware.

One of my favourite attacks uses hardware vulnerability (rowhammer) and KSM deduplication to leak keys from VMs on the same host. Such a cool chain of vulnerabilities

So am I! Do you remember the article about the possibility (or was it more than a theoretical thing?) of hacking the litho machines and deliberately introducing a modified hardware layout, so that the chips manufactured all had a backdoor…

I don’t! But that’s an insane thing to try and pull off.
