These days, mobile devices have become more than gadgets. They have become essential tools for entertainment, banking, education, communication, and even work. However, its increased usage leads to a major security risk – mobile malware threats. Cybercriminals find new ways to data breach through malware as we store more personal and sensitive information on our phones. Knowing how to recognise and respond to mobile malware threats helps you keep your mobile device secure.

This blog will explain mobile malware, how to recognise it, and how to protect your device from malicious attacks.

What is Mobile Malware?

Malware is a malicious software program/file that intentionally harms the mobile device that intends to access private data, spy on your activities, or steal your data. It can lead to significant financial loss, identity theft, or the compromise of sensitive information. Mobile malware can come in various forms, such as spyware, viruses, ransomware, and trojan horses.

How to Recognise Mobile Malware?

Knowing unusual behaviour on your smartphone can help you detect it before it causes significant damage. Here are a few common signs that show your smartphone is infected.

•   Sudden and quick battery drain is a common sign that your smartphone has malware. Due to malware, your phone tries to meet the energy requirement of the malware, which causes a sudden battery drain. These malware often run in the background, damaging your smartphone’s resources.
•   Generally, mobile malware requires an internet connection with the server to send or download any malicious files. Therefore, if you notice a spike in data usage, although there has been no change in your smartphone usage habit, it’s time to find out the culprit. Some malware sends premium text messages or makes calls to premium numbers, which can lead to higher data usage or phone bills.
•   If you experience unusually slow performance on your device, it’s a hint of suspicious activity on your smartphone. Your phone needs to work hard to support the downloaded virus or unfamiliar apps, so taking up storage space and running in the background could be why your phone runs slowly.
•   Your contacts are receiving random messages on your social media account with suspicious links.
•   When your phone has malware, it has to work harder to continue functioning, which leads to overheating.
•   If you see any apps that you don’t remember you have downloaded, it could be malware.

How to Respond To Mobile Malware?

If you find your smartphone is infected with malware, don’t panic. Here is how you can eliminate the threat and secure your device.

•   Download antivirus software or a mobile security app that will help you find existing viruses and malware. Keep your antivirus updated and ensure the latest threats.
•   Check all your installed apps and remove any app if you find it suspicious.
•   If you cannot remove malware manually, it’s time to perform a factory reset on your smartphone. As it will delete all your data and reset your phone to its original state, ensure you back up your important contacts, photos, and documents.
•   Once you remove malware, change the passwords of all your important accounts because if your smartphone is compromised, there might be a high chance that hackers have accessed this information.
•   Turn on automatic updates, which will keep your smartphone’s OS and apps up to date so your mobile device is always protected against new threats.
•   Clear phone storage and cache so that it will remove unnecessary items from storage. If you are using an Android phone, go to Settings -> Apps -> All Apps -> Click on the app you wish to clean -> choose Clear Data -> Clear Cache. For iPhone users, go to Settings -> Safari -> Click on Clear History and Website Data.
