Intelligent mobiles were a success in Europe And the rest of the countries of the world largely by Sis Wireless Communication Systems. The main thing is the communication of dice via the mobile network, but Wi -fi and Bluetooth connection are also important systems.
The latter was available in mobile phones at the beginning of the century, even before they became smartphonesallowing the sending of information or must use the transmitters and infrared receivers that certain models had in the 20th century.
Bluetooth communication is currently used to connect various devices, But it is always possible to send and receive information via this systemAlthough users do not use it for this. The problem is that this allows malicious attacks on devices that have an active Bluetooth, something that is currently necessary on several occasions, because we carry clocks, headphones or audio systems in constantly connected cars.
It is important to be clear that for such an attack to occur, you must be close. According to Briedis, CTO of NordVPN, “For an attack sent via Bluetooth to succeed, it must be at least 10 meters“. Of course, it is possible” that certain cyber attacks can be launched 100 meters. “”
To avoid or minimize the possibilities of being attacked, a series of actions must be carried out. They cannot always be made, but we must keep in mind that this type of attack is more and more frequent.
-
Put the Bluetooth devices in undetectable mode. By default, some Bluetooth devices are in detectable mode, which means that any other device can see them. If we do not correspond to a device, the right thing is not to put them this mode.
-
Reject unknown connection requests. As with emails, WhatsApp messages or calls, we must reject any connection attempt by devices that we do not know. And if they send us something, you must erase it immediately.
-
Put the passwords for connections. If possible, it is a good idea to use passwords to prevent unauthorized devices from connecting automatically. And if you are one like 0000 or 1234, you need to change it if you can.
-
Increased data use. If data use is appreciated which cannot be explained by the use of mobile, we can be checked from another device. In this case, it is best to put the mobile in plan mode and check the connections.
-
Suspicious activities. If the mobile cuts calls unexpectedly or if messages seem that we have not sent, we can be compromised. The best thing in this case is to restore the factory configuration.
-
Disable Bluetooth when not used. Normally, this prevents the risk of attacks, but it is not possible to make it when we wear an intelligent watch, or we use wireless headphones.
As always, in these cases, Common sense usually helps make specific decisions. Whenever we have a doubt about something that happens on our mobile, it is better to act by assuming the worst and to take all possible precautions.
