Security experts recommended enabling VPN when using public Wi-Fi 
Experts recommended using VPN and enabling additional protection on your smartphone. This is reported by The Sun.
The journalists talked to security experts who noticed that on the eve of the New Year, the number of fraudulent attacks on smartphones will increase. This is due to the fact that users will visit shopping centers more often and purchase goods on the Internet, where they can be deceived and robbed. The authors gave advice for iPhone owners, but the recommendations are also valid for Android phone users.
First of all, experts advised not to disable additional security features on their devices – for example, Touch ID or Face ID. It is also necessary to regularly update your gadget, since the manufacturer releases patches for it covering various vulnerabilities. When visiting shopping malls and using public Wi-Fi, the authors advised to connect to the network via a VPN: “Unsecured public networks are one of the easiest ways for cybercriminals to launch an attack.”
In conclusion, experts recommended installing a complex digital password, excluding such simple options as 0000 or 9999. The authors of the material advise you to come up with a few memorable words and associate a certain number with each – this will make it easier to remember the passcode.
In November, The Sun journalists told iPhone users, that every time a photo is sent, the smartphone transmits metadata. To prevent the ill-wisher from finding out the whereabouts of the victim, the authors recommended disabling this feature.
