Put your nerd pants on and let's take a little adventure

There's a new group of exploits going around

that can cause some serious damage to your PC.

as speculative execution, and it's similar to

Something as simple as visiting a website

could mean losing control over all kinds of stuff

which should be very sensitive and private.

So I'm talking about passwords, encryption keys.

As far as bugs go, this is about as bad as it gets.

so researchers have found these vulnerabilities

But with these things, it's only a matter of time

So last year brought us Spectre and Meltdown,

and at first, it seemed like a major vulnerability.

But of course, they were patched before too much longer.

However, at this point, it is very clear that this is

a new class of things that everyone has to worry about.

that were all announced at the same time.

- I'm not, that's why I don't want to say it.

So what separates this from traditional bugs

So there are some patches and some BIOS updates and stuff,

But at the end of the day, we now live in a different era

which means that sure you can always download a new patch,

but if there's something that's super fundamental

oh I need to buy a new processor or upgrade my computer.

So we're definitely going to get into Nerd Town here,

but the way that this all works is taking advantage of

a feature known as speculative execution.

modern processors, specifically on the Intel side,

are always constantly trying to figure out

what you're going to do before you actually do it.

So instead of saying, waiting for you to say, open Twitter,

But the issue here is a lot of times when it's wrong,

However, people have found that you actually

which on a massive scale can end up being

and actually harvest it and then send it off

And the problem here is that it's taking advantage

which legitimately mean that we get a lot of performance

if they're patched and deleted and removed.

Nothing like a bug, which not only can compromise your data

Because this bypasses traditional software things

such as antivirus as well as all kinds of different

operating system level security features,

what this means is it's just pulling data

like I said, if you have enough of this stuff
