Topic: Possible hardware backdoors - page 3. (Read 618 times)

Totally possible. In fact,  NSA has routinely inserted backdoors into computers and various devices to conduct mass surveillance. As such, it would be very much possible that there is some form of backdoor in devices that you interact with on a daily basis. I think the crux of the issue is whether your Bitcoins would be stolen or your privacy would be compromised in this case.

The answer to that is probably not, and nothing is ever completely safe.

Your hardware can get compromised by an evil maid attack because there is probably not a good way to ensure the integrity of your supply chain and thus it becomes an attack vector. However, keep in mind that most of your hardware wallet and devices are shipped in tamper-proof packaging which helps to mitigate this risk significantly.

If you're using your wallet on a normal air-gapped computer, then the possibility is slim. The entropy of your keys are unlikely to be compromised if you properly verify the installation. An airgap makes it a lot harder for information to be transferred and your keys to be compromised.

In an air-gap, your wallet probably utilizes counter-measures against side-channel attacks which makes it difficult for your keys to be compromised without your knowledge (cold boot attack, signal analysis etc). So it would be difficult as well.

Tl;dr: Is your airgap perfect? No. But the attack vector would be reduced by so much such that it becomes so difficult to compromise your keys such that it probably isn't worth it for any attacker.

Do you have any factual evidence to back your claim? If this is speculation and imagination/science fiction then no need to think about it, show some real world proof other than youtube video.

are you sure that you are not connected? depends what kind system you have.

it can be for user not connected, but for system is a idle.

there is no real one answer. depends on whether you believe corporations that they want your good

We live in times of surveillance, both covert and overt

hi

what if the router is on but you are not connected?

thank u!

it can be safe then and only then when :
1. No one has access to your hardware
2. hardware is offline.


if it is online...you know..


Online - I mean Blouetooth, WIFI, LAN, 5G, WIDI, and direct connect.

Few years ago I have read about GPS connection- it can be virused too , and their had "connect". at the time it was weird for me. but now, no. Everything is signal, code.

Hi all!

I've recently seen a video where a hacker holds a conversation about possible hardware backdoors in some pcs and other devices, mainly in the processor but also in more parts. Those backdoors would come with an OS preinstalled that could spy you.

My question is: if that is the case, how secure would be a wallet that you generate in those devices?

Would an electrum wallet that you generate with Tails OS and completely offline be safe?

thx!
