• Malicious apps. Some apps may contain hidden code that can harm your device or data. For example, some apps may ask for unnecessary permissions, access your contacts, messages, photos, or location, or send premium-rate SMS messages without your consent.
• Phishing emails or messages. Some emails or messages may try to trick you into clicking on a link, opening an attachment, or providing your personal or financial information. For example, some emails or messages may claim to be from your bank, government, or a trusted company, and ask you to verify your account, update your details, or pay a fee.
• Fake or compromised websites. Some websites may try to infect your device with malware, or capture your login credentials, credit card numbers, or other sensitive information. For example, some websites may look like legitimate sites, but have a slightly different URL, spelling, or design.
• Unsecured Wi-Fi networks. Some Wi-Fi networks may not be encrypted or protected, which means that anyone can intercept or modify your online traffic. For example, some Wi-Fi networks may have generic or suspicious names, such as “Free Wi-Fi ”or “Public Wi-Fi ”.

How to Detect Mobile Threats? Mobile threats can be hard to detect, as they often operate in the background, without your knowledge or consent. However, there are some signs and symptoms that may indicate that your device or data has been compromised, such as:

• Unusual or unexpected charges on your phone bill, such as for calls, texts, or data that you did not make or use.
• Reduced battery life, performance, or storage space, as some malware may consume your device ’s resources or create unwanted files.
• Pop-up ads, notifications, or messages, that appear randomly, frequently, or inappropriately, such as on your home screen, lock screen, or browser.
• Changes in your device ’s settings, appearance, or behavior, such as new apps, icons, wallpapers, or sounds that you did not install or authorize.
• Requests for permissions, passwords, or codes, that seem suspicious, unnecessary, or irrelevant, such as for accessing your camera, microphone, contacts, or location.

How to Prevent Mobile Threats? Mobile threats can be prevented by following some simple and effective tips, such as:

• Be careful about what you download, open, or click on. Only download apps from trusted sources, such as the official app stores or the developer ’s website. Check the app ’s ratings, reviews, and permissions before installing it. Avoid opening attachments or clicking on links from unknown or unsolicited emails or messages. Verify the sender ’s identity and the message ’s authenticity before responding or taking action.
• Be alert about what you share, enter, or store. Only share, enter, or store your personal or financial information on secure and legitimate websites, apps, or platforms. Look for signs of security, such as a padlock icon, a green address bar, or a URL that starts with “https ”. Use strong and unique passwords for your accounts, and change them regularly. Enable two-factor authentication, if available, for extra security.
• Be mindful about how you connect, browse, or backup. Only connect to Wi-Fi networks that are encrypted or protected, such as those that require a password or a certificate. Avoid using public or shared Wi-Fi networks, especially for sensitive or confidential activities, such as banking, shopping, or logging in. Use a VPN, if possible, to encrypt your online traffic. Browse safely, by using a reputable browser, enabling pop-up blockers, and clearing your browsing history and cookies. Backup your data, by using a cloud service, an external drive, or a computer, and encrypting it, if possible.
