Major flaw in millions of Intel chips revealed
A serious flaw in the design of Intel’s chips will require Microsoft, Linux and Apple to update operating systems for computers around the world.
It is believed to affect chips in millions of computers from the last decade.
Experts have said that the fix could slow down the performance of computers by up to 30% but Intel played this down, saying that “for the average user, performance impacts should not be significant and will be mitigated over time”.
I wonder if it’s tied in to the built-in NSA back door on Intel cpus?dreamnightwind, Rocco, iggy and 8 othersDesertRat2015, h-32, leveymg, beemerphill, Ferd Berfel, Marym625, PADemD, Art from Ark like thisI won't shut up and I don't waste my time teaching pigs to sing

“The UK’s National Cyber Security Centre (NCSC) said it was aware of the issue and that patches were being produced.
In response, Intel said the issue was not limited to its processors and that it was working on a fix.”
sounds like a backdoor cheat that became know to the wrong team

4. Or this is an excuse to open another back door
In older machines.
I just dont trust these people…and you think you’re going to stop this simply by ‘pulling a lever’, in a booth, behind a curtain, every 2 years? - Know yourself. And if you need help with that, call the FBI. - There is only ONE solution to this mess: New Party !

5. I'm so happy I always use AMD chips..
…. back in the day I could not believe MS chose the Intel platform. Their chips were ridiculously inferior to competing products from Motorola, largely because of the idiotic “memory model” (anyone remember those?) architecture used for addressing. The “memory model” paradigm imposed a 20-30% penalty on programming productivity. It was a seriously bad joke.
I responded by always going out of my way to use AMD processors. Cheaper AND better. Now, I get my payoff

10. Been using AMD for years. Cheaper and more reliable
Never had an AMD processor blow. Seen more than one Intel cpu go dead and take the motherboard with it.I won't shut up and I don't waste my time teaching pigs to sing

12. Been AMD since the 486
Had an Intel 4×100 at work, compared to the AMD 2×66 I had at home, no contest.
That was on large CAD program. On an I Core 2 here, given to me.
Waiting on parts for my Athlon box. Can hardly wait….

14. The company I work for sent a notification about another virus

16. AMD chips are also affected.
And so are ARM CPUs that you find in phones.
A reliable source, The Register (biting the hand that feeds IT) published an article about it. It appears that AMD and Intel were working with Microsoft and Google to come up with a patch, and make an announcement jointly. However, El Reg (slang for The Register) released the info beforehand.
The Register even has a hit piece where Linus Torvalds (the programmer who wrote the Linux kernel) said, “”I think somebody inside of Intel needs to really take a long hard look at their CPUs, and actually admit that they have issues instead of writing PR blurbs that say that everything works as designed. Is Intel basically saying ‘we are committed to selling you shit forever and ever, and never fixing anything’?”
Here are the links to the articles: http://www.theregister.co.uk/2018/01/04/intel_amd_arm_cpu_vulnerability/ and https://www.theregister.co.uk/2018/01/04/intel_meltdown_spectre_bugs_the_registers_annotations/

18. That boost came at a price.
And now, the inside dirt has it that this microcode bug in the CPU not only means that they will have to redesign the next generation of CPUs, but that in order to fix older ones, including AMD processors, will cost about 5-25% hit on performance. Looks like you have no choice now.

6. FYI best explain I've seen for this faults cheap memory chips.
And it is that that allows this OS problem to be so, uh, catastrophic.
The VM register leaks allow one theoretically to flip privilege bits for your process by frobbing the memory. Suddenly you are root.It ain't the things you don't know that hurts you, it's the things you know that ain't so.

8. Meltdown, Spectre: The password theft bugs at the heart of Intel CPUs
AMD, Arm also affected by data-leak design blunders, Chipzilla hit hardest
Summary The severe design flaw in Intel microprocessors that allows sensitive data, such as passwords and crypto-keys, to be stolen from memory is real – and its details have been revealed.
Thanks to Intel’s cockup – now codenamed Meltdown – that data is potentially accessible, meaning bad websites and malware can attempt to rifle through the computer’s memory looking for credentials, RNG seeds, personal information, and more.It ain't the things you don't know that hurts you, it's the things you know that ain't so.

9. Go back to one-time pads and dead drops, if you want secure communication.
If your computer has a browser or email connection, they have a way in. Or is networked with any others that do. Even in a completely airtight machine, file transfer by any media is risky, if the transfer media isn’t completely trustworthy. Good luck with that.
If my computer runs any slower, it will be useless. Maybe, that’s the point.

11. I don't keep anything important on my computer.
Any data on my computers is stuff I’m not worried about.
Anything critical I keep in the most secure location of all-inside my skull.I won't shut up and I don't waste my time teaching pigs to sing

17. Don't you worry about
Your banking, credit, medical, or other records that are stored on other computers, and posibaly in the cloud? These hacks effect EVERYONE, unless you live under a rock, in a cave, in the middle of nowhere and don’t use money.

20. Those things, along with my fingerprints have been on a government file for
along time. I don’t worry about things I don’t have and never had control over. As far as anyone hacking my personal computer, I wish them luck-each attempt warns me of someone trying.I won't shut up and I don't waste my time teaching pigs to sing

19. Wow, very serious. Possible fixes
First, it effects more than just Intel chips. Seems different manufacturers use slightly different techniques to predict and preload which code will be needed next, which is what leads to this vulnerability.

The above works for Opera too, since it’s based on Chrome.
Only the more recent versions of Firefox have the first party isolation feature, so if yours doesn’t, update.
I made these changes, and so far everything seems to still work.
Any advice on whether this will help, or on other things to do, will be eagerly received.
Might be time to change passwords. Any opinions on a good password management site, or whether to trust such things?
