Can the viewing angle follow the state to monitor the mobile phone?

As long as the mobile phone has a GPS module, it can be realized with high positioning accuracy. We usually use XX taxi, XX map, etc. , using base station +GPS cooperative positioning. Of course, GPS is limited to outdoor positioning, and the indoor error is large. Machine friends who have seen in the name of people should remember that when tracking Ding in the play, they tracked his mobile phone GPS.

2. Through the wireless network

After the phone turns on the WiFi function, it can be accurately positioned without connecting WiFi. When the phone turns on WiFi, it will scan and collect the WiFi signals of the surrounding routers. No matter how strong or weak it is, whether it can be displayed or not, as long as there is one, it can be scanned.

Each WiFi hotspot has a unique address, and the server retrieves the geographic location of each WiFi hotspot, and then calculates the geographic location of the mobile phone according to the strength of the signal. This method is more suitable for indoor use, and its accuracy is less than 10m.

3. Positioning through the base station

As long as your mobile phone has a signal, it will automatically connect to the base station with the strongest signal, so that you can find the location information of your mobile phone through the location of the base station. The phone number of each SIM card is unique. When your mobile phone is connected to the base station signal, this data will be recorded and uploaded, so which base station your mobile phone is connected to can also find out your approximate location. However, the positioning error of base stations is generally large, which is100-300m.

Will the phone be monitored when it is turned off?

The hacker implanted some kind of rogue software in the mobile phone of the monitored object in advance. When the user turns off the phone, the phone does not really turn off, but enters a low-power mode, and the screen is completely black. No matter how you press the button, it doesn't respond. It seems to be turned off, but some key communication chips of the mobile phone are still running in the background.

In this "dead" state, hackers can continue to control the mobile phone, such as sending instructions to the mobile phone, activating the microphone and listening. If you are not a professional, you can't tell whether the phone is really turned off.

Will the SIM card of the mobile phone be monitored when it is unplugged?

In fact, as long as the mobile phone is turned on, it will be connected to the base station signal acquisition network by default, so that the base station can obtain the ID information of the mobile phone, and then it will judge whether there is a SIM card. So even without a SIM card, others can't find the phone directly by listening to the number, but they can also find out where the phone has been turned on by investigating the phone ID associated with the number, so as to track your location information.

Here is another scene in "Taking in the name of people". The informant threw the SIM card into the toilet and was still found to have made a phone call from a base station near the provincial party committee.

The following five points are consistent, indicating that your mobile phone is likely to have been monitored:

1. I didn't buy the mobile phone myself, or the mobile phone was lost for a period of time and was found back (maybe a monitoring chip or software was implanted;

2. Occasionally, the mobile phone will fail and the key response will be slow;

3. A strange number with no impression appears in the address book;

4. The communication cost is soaring (the information you receive or send to others will be secretly sent to the "monitor" by the mobile phone);

5. The 5.SIM card has enabled the three-way calling function (if your mobile phone has enabled this function, the incoming and outgoing calls will be controlled by the "monitor" but will not be discovered by you).

How to prevent mobile phones from being eavesdropped?

1, take out the battery.

The mobile phone may be in a "fake shutdown" state without unplugging the battery. For example, many mobile phones still ring when the alarm clock is turned off. But this method is almost impossible, because most mobile phones on the market can't disassemble the battery.

2. Strengthen awareness of prevention and avoid using malicious software.

Download software should be obtained from the regular application market, avoid opening SMS attachments, refuse to install applications of unknown origin, and pay more attention to installed applications.

3. Virtual positioning

Nowadays, many mobile phones have the function of "virtual location", and it is easy to create fake locations to confuse monitoring.

The more you know about mobile phone monitoring, the more you think about it. Maybe you still think surveillance is far away from you. In fact, monitoring is everywhere in the online world now. ...
