Remote blocking of Android smartphones and Windows laptops in case of US sanctions?

Question

Operating Systems

Hello, please tell me if I turn off all wireless networks on my Windows laptop and Samsung Android smartphone: mobile data, wifi, Bluetooth, NFS, GPS. , And turn on airplane mode.
Then corporations in the event of harsh sanctions will be able to block the operating system in this case?

Answer 1

Firstly, no one will deal with such a blizzard.
Secondly, there are 100% backdoors)

Answer 2

If they don’t learn how to burn out the processor in the phone with a laser from a satellite, they won’t be able to.
Although, again, no one guarantees that the phone does not have some kind of backdoor that is tied to SMS or a microphone.

Answer 3

In fact - no, but a backdoor can be built into the smartphone, as Vasily Bannikov said, which can enable all functions and use other smartphones to send requests to block OC via bluetooth, which enabled the backdoor to your phone.
With Windows, too - if it is very foolish at first using the methods described above, they will infect your smartphone - it will transfer it to the computer and they will both fail under US sanctions.

Answer 4

in case of severe sanctions

What are these "hard"?
When there are tough times, the owners of corporations will not be up to it, they will rush to the bunkers in order to escape retaliatory sanctions. And there will still be no cellular communications on the planet for at least the next 100 years after tough sanctions (or never at all). The laptop must be placed in a Faraday cage in advance, otherwise the electromagnetic pulse that came from the nearest epicenter of the sanctions will easily burn the microcircuits.

Answer 5

If you set the task of blocking the largest possible number of devices , then information can be transmitted in documents and files in the generation of which the subordinate software participated.
Adding a unique set of bytes to a video file, an office document and any other file that you could view on your device, which is a code word for blocking the device, is technically very simple .
Also, in addition to radio, there is a way to transmit information, for example, by sound (for example, a desktop machine that is still connected to the Internet, through some browser, transmits the necessary code signal at ultrasonic or infrasound frequencies and all the surrounding devices receive it. And yes, smartphones also can be repeaters of this signal, and any others with a speaker.An excellent example is DVRs with the function of viewing video with sound (I know that the time there may be incorrect, this is not so critical), any taxi driver will immediately become a mobile repeater, infecting a command to block everything surrounding devices.Flash
drives and external drives can also be a carrier of information, there are a lot of places where the necessary signal can be kept hidden.
And yes, the signal can be something like - to block the functionality in a year ... the signal to be transmitted all this year, as soon as the sanctions begin, all this time the devices will work and spread the command to die farther and farther.
The vast majority of software that gets on our devices passes through servers and, most importantly, software owned by companies controlled by the United States. We are all firmly and irrevocably addicted to this needle, and the disconnection of any country from this will overthrow it for decades or even a century in development back.
ps at least somewhere we are protected? perhaps there will be a small number of devices, for example, those lying in warehouses and store shelves, which could be turned on in a room isolated from 'infected' devices (i.e. you need to already understand what happened, which in principle is already an almost impossible task), and install applications on it, collecting them from source texts (there is still a problem where to get them) and almost certainly this software will be hopelessly outdated, incomplete, .. I am silent about the documentation, probably many have already noticed that offline without the Internet is something intelligible to do already almost impossible.
another vector of hope for the possibility of at least putting together something that works comes from the mechanism for determining friend or foe, sof, which should attack devices, must somehow determine who owns the device, and all devices sold in the country are initially marked as 'for such and such a region or country ' but private traders could make purchases on their own in other countries, especially since very often this is a way to save money, but there will not be so many of them, and in most cases the settings and pattern of their use (software set, browser history, location history at the same ip addresses and etc.) will show who owns the device.

Answer 6

Nobody knows how Windows works and what bugs are built into it. But in the case of "harsh sanctions" I think all of us will not be up to laptops.
Because "... You need to take medicines with you, as well as a supply of food, documents and money ..." (C) Civil defense instructions from the site of the city hall.
But if it’s not about sanctions from the back, but just copyists want to show who the hillock is here, then they have such opportunities :)
