China fails Micron's products in security review, bars some purchases​

BEIJING :China's cyberspace regulator said on Sunday that products made by U.S. memory chip manufacturer Micron Technology had failed its network security review and that it would bar operators of key infrastructure from procuring from the firm.
According to China's broad definition of critical information infrastructure, this could include sectors ranging from transport to finance.
"The review found that Micron's products have serious network security risks, which pose significant security risks to China's critical information infrastructure supply chain, affecting China's national security," the Cyberspace Administration of China (CAC) said in a statement.
Micron said it had received the CAC's notice of conclusion of its review of the company's products sold in China, and "look forward to continuing to engage in discussions with Chinese authorities".
The CAC neither provided details on what risks it had found nor what Micron products would be affected.
China announced its review of Micron's products in late March. The company said at the time it was cooperating and that its business operations in China were normal.
The governments of the United States and China are in a dispute about chip technology. Washington has imposed a series of export controls on chipmaking technology to China and moved to prevent Micron rival Yangtze Memory Technologies from buying certain American components.
Micron derives around 10 per cent of its revenue from China, but it is not clear if the decision affects the company's sales to non-Chinese customers in the country.
The larger chunk of Micron's products flowing into China are being purchased by non-Chinese firms for use in products manufactured there, according to analysts.
China in September 2021 imposed rules aimed at protecting critical information infrastructure, which require their operators to comply with stricter requirements around areas such as data security.
Beijing has broadly defined the industries it considers "critical" as ones such as public communication and transport but it has not specified exactly what type of company or business scope this will be applied to.

As if you guys know WTF you are talking about this in the first place.

but they are not the first choice if they want performance
by the way how you trust a company that allow this guy

go and play with their latest production line

 

[gambit]

the problem can be in controller they use for those nands and DRams .
that controller can be programmed to do many things while as you said its nearly impossible to do these type of activities with nands and drams themselves while those components are pretty much standard you can do many things with those controllers.
for example at its basic design something like stuxnet to access them or design some secret interrrupts ionside them to access them remotely and read data stored in those nands and drams

Then who makes those controllers? How long have those been on the market? No one ever took them apart before? You think you got an original idea with that argument? Do you know what you are talking about?

If a car was used in a bank robbery, you cannot punish the radio or tire manufacturer, get it? In this case, in blaming Micron memory products you might as well blame Micron's silicon wafers suppliers.

exactly as how powerful Huawei prevented usa government present its evidence anyplace but behind closed doors

Bring on the evidence on how did Huawei do that? Do you even know what you are talking about in that case? I doubt it.

Just how micron did and brands like Samsung build their own controller you must answer who build the controllers for micron if it's not micron then only god knows how unsecure micron solutions are

Micron's core products are memory modules, of which the modules contains necessary controllers.

The controllers are not 'hackable'. You have been watching too many shiddy 'hacker' movies. See posts 5 and 29 in this thread.

no they are not hackable unless micron put the necessary code inside them , and micron can easily put the code there

And to this day, no one has found any with who knows how many Micron memory modules in whose hands all over the world. You are feebly defending China by making up scenarios that COULD NOT exist because Micron do not make appliances. Keep on making a fool out of yourself.

Well, we still don't know the vulnerality.

China said Network security, so don't think is this which affect Micron, SK Hynix and Samsung memory,

Row hammer - Wikipedia

en.wikipedia.org

Row hammer (also written as rowhammer) is a security exploit that takes advantage of an unintended and undesirable side effect in dynamic random-access memory (DRAM) in which memory cells interact electrically between themselves by leaking their charges, possibly changing the contents of nearby memory rows that were not addressed in the original memory access.​

micron own crucial that make ssd and memories and the building of appliance is not important , stuxnet targeted a single piece of semiconductor not appliances

There is nothing to prevent China from showing those alleged Micron 'risks'. Bring it.

 

[IblinI]

So call the truth -- that Micron's shit is great stuff but we just want to retaliate.

But China know better so the technical facade was erected -- national security risks.

what a loyal vietnam oldman.

what a loyal vietnam oldman.

What does Viet Nam have to do with this?

just surprised of how loyal a person can be to his new master even after what this country has done to his motherland, just human thing.

the same thing that stop usa show evidence against Huawei

We have gone thru this before. Huawei make APPLIANCES and by Chinese laws, Huawei is LEGALLY obligated to collect customer data and transmit those data to the Chinese government. Appliances can do this because they are much more complex devices with much more complex s/w than memory modules by any manufacturer.

Huawei Security Scandal: Everything You Need to Know

Is it safe to use Huawei phones and should the manufacturer be trusted to make 5G network equipment?

www.forbes.com

There is growing concern about Huawei from governments around the world. So much so, that many have blocked telecoms companies from using Huawei gear in next-generation 5G mobile networks.​

How many governments are concerned about Micron's memory modules? Of course, China can always bribe a few African governments to go along with what China claimed.
