In the digital age, smartphones are not only a communication tool but also store a lot of personal information, from bank accounts to work schedules. However, this convenience also comes with the risk of being tracked or installing Spyware that users are not aware of.
According to Mr. David Emm, senior security expert at cybersecurity software company Kaspersky (brunch in the UK), many current Spyware programs can operate silently, recording call logs, messages, GPS positions and even environmental sounds without leaving a clear signal. However, users can still detect unusual signs if they observe closely.
One of the common manifestations is that the device runs out of battery faster than usual. The underground surveillance software will consume energy, causing the phone to heat up unusually even when not in use.
In addition, the sudden increase in mobile data, especially when no application is updating or transmitting big data, is also a warning signal.
Users should also pay attention to strange applications of unknown origin or automatically installed.
In Settings > Applications, check the list and remove unfamiliar applications.
- On iPhone, go to Settings > privacy > Analysis & Upgrade, check system activity reports to detect unusual behavior.
- For Android, an effective way to check is to go to Settings > Security > device Administration, check if any application is being illegally granted permission to manage.
Another sign is strange noises when calling, or the phone is unusually bright with a screen even without a notification. In many cases, this is a manifestation of monitoring tools that activate remote recording or recording videos.
Mr. Emm recommends: Uservers should regularly update the operating system, download apps from official warehouses such as Google Play or the App Store, and use reliable security software.
In addition, restoring the root settings is a way to clean the device when suspected of being hacked, but need to back up data before doing so.
In a technology world full of digital traps, being vigilant and equipped with basic knowledge about device safety is the key to protecting personal information from the eye of the unknown.
