Zombie loads confusion please help me

[Ebony Falcon]

So I have a 8700k and saw some stuff on Facebook that basically said there going to just disable hyperthreading off of my cpu ? Wtf 

 

1what at is the actual fix/patch doing ? 

2When is it out ? 

3Will I loose hyperthreading off of my cpu? 

4, will zombie load even effect me as someone who only games and browses the internet and has no sensitive information stored 

5, will it be better for me to just disable the patch and carry on as I was 

 

does anyone actually know wtf is going on 

and why are reviews doing comparisons of cpus with and without hyperthreading ?

No, it is merely a suggested fix, it won't be removed automatically. Intel suggests that you remove it manually.

Unlikely

 

I asked about Zombieload myself recently:

Basically the only real fix to the vulnerability is to disable hyper-threading completely as that's what the exploit uses but unless you're handling sensitive data or running VMs in a data center, I wouldn't really worry about that one. You won't have it forcibly disabled on you, it's just the suggested complete fix for impacted CPUs.

So can u get rid of it wot malware bytes or reinstall widows if ur effected ?

No. It is an exploit - intel will have to work on a patch to fix the vulnerability

Coffee Lake already has most of the needed hardware level fixes around any of these issues related to HT so you don't have to any thing about it realistically speaking. With that in mind whoever's on Kaby Lake and older is indeed up to a bad time if the fixes are as drastic as they sound to be.

lol

 

"

From what I've read Zombieload can be triggered from javascript stuff on webpages as well as local programs.

 

Administrator access is definitely not required. Viewing an infected website seems to be all it takes.

 

Intel and the CVE Organization (that's not the actual name of the organization but I don't know the actual name) have determined that this class of vulnerability is ranked as "medium" severity which means really bad but it means there is the potential for worse stuff."

 

first post in the thread, so literally if you visit one bad webpage there is potential for any of your sensitive information to be stolen, sure it's not bad now.... but the simple fact of the matter is do you want to buy processors that have minimal performance to price ratio at the high end, are non competitive in the mid range, have one shrinking use case where price is justified (1080p gaming on high refresh rate moniter with gtx 1080+ GPU), and will likely loose that advantage within the next 6 months to zen 2.... and on top of that have the knowledge in the back of your head that simply visiting a bad webpage could enable someone to access all your passwords and sensitive data?

 

There is a reason Intel stock is down 25% in the last 30 days, and as an AMD shareholder who has been in since before it was $10 I can say the stock price relationship on AMD and Intel alone is enough to justify a spike in the amount of zombieload attacks, it really does't take much time or effort to register for advertisements of some of the shady sites you may visit and simply redirect to another webpage with an attack.....

 

If you already have a Intel CPU should you worry? Maybe, maybe not, but you should be pretty pissed tbqfh, you either lose peace of mind or performance, and you still payed a premium, if I were you I would take advantage of the fact Intel chips hold their values relatively well because that might change a bit going forward from this point and sell the GPU + mobo and buy a 8 core ryzen, if you buy a gen1/2 you might even have some money in your pocket and with zen2 you might even come out with performance rivaling the 9900k without having to spend any extra money.... So maybe wait for Computex/CES lol

Will likely come with more performance impact

If this keeps up, eventually one's CPU will perform half as it should

Well I’ve been saying this; but as I can’t see in the future I left my comment for what it is

Really ? Sorry where did u get this info ? 

So I don’t have to do anything but keep windows up to date ? 

I’m not updating bios because last time it crashed and I had to reflash original bios with flash back and it took me all night to get it figured out etc

the exploit is at the most basic level of operation, imagine if there was a problem with a car that it made so much horsepower it always spun on acceleration, so it quickly burned thru tires, but the tires it had were the best physically possible, well then the only fix for the problem would result in the car being slower. The basic level of operation is there to increase performance, any fix to filter for exploits would add instructions and complexity to everything the processor did involving this performance gain feature and thus would make its performance benefit less. Intel has added a feature that makes their processors have an edge but the feature is unsafe, imagine buying a guy with a special part that makes it shoot the bullet faster, more accurately and with more power, but it makes it more likely to blow up in your face, then imagine this gun costs significantly more money; that is probably a better analogy.

“We conclude that disabling hyperthreading, in addition to flushing several microarchitectural states during context switches, is the only possible workaround to prevent this extremely powerful attack,”

 

https://www.pcgamesn.com/intel/zombieload-mds-vulnerability-security-patch-hyperthreading-mitigation-performance

 

 

Microsoft also recommends that “to be fully protected, customers may also need to disable Hyper-Threading.” But that’s up to your discretion.

 

 

 

however

 

 

"Chrome OS has, by default, disabled HyperThreading."
