Much public Wi-Fi exists (stations, hotels, coffees, etc.), they are open to customers but they are therefore also more open to cyberattacks. It is recommended not to use open Wi-Fi hotspots and instead use private mobile networks. If you need to connect to a public Wi-Fi network, it’s best to use a virtual private network called a VPN.
2. Install antivirus

3. Do not click on SMS links
We must be very careful about the practice of smishing (phishing by SMS). It is still very widespread and many people are still having it. The technique consists of sending you an SMS pretending to deliver a package or an update to your vital card, for example, in order to encourage you to click on the link contained in the message. The goal of cybercriminals: is to trick you into sharing personal information (e.g. credit card number) or unwittingly downloading and running malware on your device.
The advice is therefore to be extra vigilant on text messages received from unknown senders: do not click on the links and do not reply to them. This also applies to emails received in your mailbox. We also talk about phishing.
4. Do not download apps from unknown sources
Beware of the apps you download! First, do not upload a mobile app from an unknown source. Instead, rely on known app stores such as Google Play Store or Apple Store. And even in these most famous stores, check the information about the application before downloading it. The opinions of other users can give you a good indication of the reliability of the application, for example. You can also check the data to which the application will have access.
5. Update your OS as soon as possible
When there’s a new update to your operating system (Android or iOS), it frequently includes fixes for security vulnerabilities that malware can exploit. So if you receive a notification about this, do not wait to update. To ensure that the latest update has been made, go to your Settings on Android and in the Settings > General > Software Update on iPhone.
6. Take precautions in case of loss or theft
If lost or stolen, your phone is at risk. Here are some tips to protect your data:
- Never deactivate the PIN code of your mobile and change the one set by default (do not leave 0000 for example),
- Set up an automatic lock delay (after a few seconds of use, the phone should lock),
- Keep your smartphone IMEI number to block it if necessary and avoid fraudulent use.
