Intel 'Downfall': Severe flaw in billions of CPUs leaks passwords and much more
There is a serious security flaw in billions of Intel CPUs that can let attackers steal confidential data like passwords and encryption keys. Firmware updates can fix it, but at a potential significant performance loss.

Oh no.
im honestly not really surprised anymore. i fully expect to see a lot more of these types of bugs in the coming years
Just wait for quantum computers to take off, our current encryption can be broken with them
absolutely. a lot of currently in use public key schemes may be broken with those. more recently there have been a few newer algorithm such as kyber that do have a chance to hold. think NIST is also holding a bit of a competition, but dont quote me on that. i really dont know alot about post-quantum crypto
I'll see your quantum computers and raise you electronic analog computers.
Passwords are becoming speed bumps, not road blocks.
What a shitshow.
I'm glad I'm running AMD CPUs on the computers I actually use for anything that could be considered sensitive.
Are you sure AMD CPUs are safer?
At this point, I almost feel like we need to start over with the idea of pipelining in CPUs, as though it were some kind of original sin. The fact that the most basic of errors in pipelined logic are referred to as "hazards" should have been a hint.
If the vulnerability is part of a feature designed for niche use cases, then it's far safer than one that affects general use. I highly doubt most people are going to run virtual machines, plus the main target is server hosts that use VMs to run multiple servers of the same type on the same box. I might run a VM at some point in the future, but when I do I'll take steps to avoid any issues, like only enabling virtualization in the first place when I need it. Sure, that means I need to boot into the UEFI before and after every time I run a VM, but that's not an issue on the system I'd be running it on. And I'd rather have that inconvenience than have to worry about a vulnerability at all times.
In short, it's a matter of risk management.
