Ok, wow, in my 30+ years of being a computer geek and software engineer, I've never read anything as bad as these new vulnerabilities: "Meltdown" and "Spectre".
Meltdown:
This violates the separation between user apps and the kernel. Potentially allowing an app to just..view raw memory..secrets..data..everything. This effects...every Intel processor made ..in the last 20 years! Yikes! Any operating system, that doesn't matter!
The good news is that it can probably be patched with software, though it may slow down your machine as much as 30%! (You'll be losing some of the speed benefits of out-of-order instruction processing.) For Linux users (which you should all be), this will be patched with Kernel 4.14.11 (when it's available, not quite yet), which will include a KPTI patch.
Spectre
Spectre might actually be worse then Meltdown, if that's possible. It's harder to exploit...but also harder to defend against. It is similar in nature, allowing different, well written apps to view each other's memory, breaking down the barriers that hardware would normally enforce.
This flaw affects even different types of processors, not just Intel, but ARM and AMD as well. There may be fixes coming to harden software against these vulnerabilties, probably many needed.
What to do:
For Meltdown, try to get that patch as soon as you can ( and it becomes available). For Linux, this would be Kernal 4.14.11 which hopefully comes in a few days. For Spectre, keep your eyes peeled for any patches and fixes for this.
For all you crypto-currency users out there, which is all my readers I'm sure, stay on top of this. Super important.
(the famous Scream picture)
It's all over the news and it seems that there is no escape for almost every device that has a chip in it. Looking out for a patch and fix but nothing so far... Yikes...

This is a nightmare scenario the tech world dreads. My Linux systems will get updated, but when will my Android phone get fixed? Our connected devices are vulnerable and some may not get patched. Very worrying

This is absolutely terrifying!! I read some articles from MSM, but I didn't realize of horrible Meltdown and Spectre are until reading this! Hopefully they get those patches live ASAP!

thanks for the info. i've heard about it yesterday..nothing much to do for windows from what i can tell. this is pretty big and unfortunately might spur would be hackers to expoit it, now that they know about it.

My take on it: https://steemit.com/conspiracy/@mindhawk/introducing-the-intel-management-engine
This year has seen the evisceration of any idea that intel/google/apple/MSFT/AMZN are in any way trustable platforms. It is simply the logical conclusion of the corporate integrated state that large projects like this will develop backdoors and it is in everyone not so affiliated's interest to develop computing systems through other means.
Actually, no indivivdual benefits from this nationally socialized computing philosophy, it is actually fascistic in nature, the end of the individual.
With AI and infinite storage, and as a strike against crypto, as in they could make huge viruses with this that could affect global computing, or just steal keys, yeah, time to be really sure about keeping your keys offline.
I rewatched the first few episodes of the reboot of Battlestar Galactica also. I suggest everyone else do the same.

If you add to that the fact that most app don't erase the cryptographic keys they use this looks pretty bad. I am just wondering how quickly this will be exploited.

Hello @neoxian,
Extraordinary good update, until you share this i had no idea what was that. Thank you.

As digital currency increases in value, there is greater incentive for key stealing and such. The exploits are going to get more and more sophisticated and more difficult to defend against. The holes will be patched, but a lot of data can be stolen between exploit and patch. @ironshield

Update your OS.
For browsers: FF, Edge and IE have realeased updates. For Chrome:
Enter "chrome://flags/#enable-site-per-process" in Adress bar and click on "activate" after "Strict site isolation).

So this exploit could potentially extract our user names and passwords we have saved? I read about it yesterday but it was really vague. I think they kept it that way to not give the goods away to all the hackers while they work to fix it. Im just trying to figure out how scared I should be, or what I should be doing as a security step instead of just waiting lol!
