New unfixable High Risk Security Issue on Intel CPU's. (Intel knows it since Mai 2019).

They can just try to make it harder to get inside a system, but not fix it.

There also another Security Risk on all AMD CPU's back to Bulldozer named "Take away".

But it can be fixed by a Software Upgrade (UEFI).

Re: Ryzen tests

Some findings still suggest that once your network has been infiltrated, there are
far more easier and efficient ways to gather info rather than attacking the cpu.
Recommendations are as always, a multi-layered firewall.

Yes, but you know those security problems with Intel are pointed in many cases to the Cloud and Datacenters and big Servers.

From that moment it comes out that someones datas/secrets are stolen, the world would have a much bigger problem then with Corona Virus.

But with this last security issue from Intel it's even possible to read out bitlocked harddisks because they use this machinecode.

There are not only datacenters which datas must be safe.

I'm still convinced that many of those security holes were placed intentionally.

There's no easyer way to get datas then if you are the one who is controlling/selling the hardware.

They or intel just get the bill for this decision 10 years ago.

Hehe, this AMD Security Hole, Zombie-load light, "Take Away"  ... the Team who discovered it is payed by Intel smile

Just let's wait what AMD is saying.

But i surley i think it's approved, otherwise it would have not been wisely to bring this out. 

...

And there's another difference. Only parts can be read out with "Take away" as in Intel cases entire data sets are affected.

Thanks a lot for your work! I find it hard to read a paper which is irrelevant to my profession. Is this vulnerability as severe as Meltdown or Zombieload?


Daniel Gruss
@lavados
Certainly not. The attacks leak a few bit of meta-data. Meltdown and Zombieload leak tons of actual data.

As far it seemse AMD will be able fix it by an UEFI Upgrade.

Re: Ryzen tests

You know, ... the bitter part on this Intel Crypto Leak is that it can't be fixed.

This Cypto key is used for "Intel Management Engine" (ME), UEFI-Bios, DRM, the Trusted Platform Module (TPM) and the Software Guard Extensions (SGX), (Servers).

It was builded and sold to everybody as a security improvement. Now it seemse it's vice versa.

If this Crypto Key is read ot you have access to everything on this PC, DataCenter, Server etc. and this stays like this forever.

...

Btw. There are ways to deactivate as example Intel ME and others, but the point is, that this deactivation is done by a kill switch inside Bios but this kill switch is after the crypto key is allready loaded, (which happends before the bios is loading). 

(Dell as example has this option and others also).

Like this it seemse it's really not fixable with a patch.

I got error messages about my TPM module (it say something like encryption still works, bitlocker), im on amd now, but the windows install originated from intel platform (win7) and then updated to win 10 on this amd platform.

Intel - New Security Issue  -  LVI (Load Value Injection)

LVI affects Intel Core-family processors from Skylake onwards with SGX support


https://www.bleepingcomputer.com/news/s … dware-fix/

https://www.hardwareluxx.de/index.php/n … soren.html


Not that bad like Intel Crypto Key Issue, (Take away), but still something what costs Performance to close it.

...

List of affected CPU's

https://software.intel.com/security-sof … -cpu-model

...

Closing LVI will cost exorbitant performance.

An anser from Uni Graz.

They say Intel has to make a complete new CPU. LVI cant be closed without huge performance loss.


„Diese Lücke ist sehr schwer zu schließen“, erklärt TU Graz-Forscher Daniel Gruss, der mit seinen Kollegen Michael Schwarz und Moritz Lipp einmal mehr im Zentrum der Entdeckung steht. „Es braucht dafür entweder einen ganz neuen Prozessor oder einen tiefen Eingriff in die Software. Die von Intel und uns parallel erarbeitete Software-Lösung wird massive Performance-Einbußen mit sich bringen.“ Das Team informierte Intel im bereits im April 2019 über die Entdeckung. „Wir haben uns auf diese lange Verschwiegenheit geeinigt, um Intel genügend Zeit für die notwendigen Fixes zu geben und die Computernutzenden keinem Risiko auszusetzen.“
Auch diesmal empfehlen die beteiligten Forschenden, alle Sicherheitsupdates der Hersteller einzuspielen und das eigene Computersystem abzusichern.

It looks bad for Intel. Up to 75%+ performance loss. (SGX)

Btw. Privat users do not need SGX. Like this it affects only servers with activated SGX.

Poor color accuracy (65% sRGB, 49% Adobe RGB)

They allways make the same mistakes, also HP has horrible bad screens Displays.

Sadly some companies have the sole right to produce Laptops with 4800H.

I guess there is also none with just IGPU, which would be good enough. (At least for Workstations).

But anyway. This Mobile CPU is really nice.

Hmm... there are rumors that Ryzen 4000 is coming in 5nm+

The reason, they say, due the blockade of Huawei they have free production capacities and AMD made an agreement with TSMC.

Another reason is, that 4700G disappeared in Bios, but others came in.

...

And Intel is still at 14nm+++++ etc  smile
