There are programs and devices whose functionality includes intercepting your calls, SMS, geographic positions and photos. Of course, programs and software do not allow intercepting traffic in the same way as special services do, but you can get your data. Indirect signs are considered to be:
1) High temperature of the device
The device tends to heat up during active operation, but if no one uses the device, but it is heated – here it is, an alarm bell. It is likely that spyware is actively running.
The battery life expires over time and is quite a natural process, if after a year of use the charge lasts 12 hours instead of two days, but if the device is only a couple of weeks or months old, and the charge stops holding , then this is a reason to worry, because a malicious application can drain the battery.
It would seem: Turning off the phone is a common process, but it can also provide useful information. If the device takes longer than usual to turn off, the backlight of the phone is on for a long time, or it does not turn off at all, then you should worry. Although this can be attributed to normal technical problems.
4) Independent life of the device
The phone turns on, turns off, installs dubious applications, does not want to update, and many other dubious actions indicate that the device is clearly infected and someone controls it. Yes, the operating system can also be naughty, in which case it can be reinstalled.
Interference also occurs due to poor communication, but if you hear it too often, then this is cause for concern, even if the connection is good.
1 ) Use an antivirus, such as Dr.Web or McAfee
2) Check the system for viruses and remove them using the same program
3) You can use the program spywarn, which was created specifically for tracking espionage
4) Contact your mobile operator if you are sure that your phone is being tapped. They have a large set of tools for detecting a spy.
