To protect yourself from mobile threats, Kaspersky shares the following recommendations:

• Download your apps only from official stores like Apple App Store, Google Play or Amazon Appstore. Apps from these markets are not 100% failsafe, but at least they get checked by shop representatives and there is some filtration system - not every app can get onto these stores.
• Check the permissions of apps that you use and think carefully before permitting an app, especially when it comes to high-risk permissions such as Accessibility Services. The only permission that a flashlight app needs is to the flashlight (which doesn't even involve camera access).
• A reliable security solution helps you detect malicious apps and adware before they start behaving badly on your devices. Conveniently, you can get protection, like Kaspersky Premium, directly from mobile operators.
• A good piece of advice is to update your operating system and important apps as updates become available. Many safety issues can be solved by installing updated versions of software.
