Keeping Your Android Phone Safe from Malware: A Guide
Introduction
Despite efforts from manufacturers to keep Android phones safe, malware still finds its way onto the Google Play Store. While Google is doing its best to keep the Play Store safe, shady developers can still find ways to get past security measures. So, what can you do to keep your phone and data safe? Follow this guide to protect your device from malicious actors.
What is Malware?
Malware is a program designed to exploit computer systems, networks, or devices. Android smartphones are vulnerable to malware, which can range from trojans to spyware. Malware can infect your device in several ways:
- Opening suspicious emails and their attachments
- Connecting to unsafe public networks
- Browsing shady websites online
- Mounting an unknown USB device
- Downloading infected software
Google Play is a common source of malware, as developers can slip through security measures. Once malware is installed on your device, it can steal personal data, corrupt files, lock your system and files behind a paywall, delete everything on your phone, trick you into phishing scams, or hijack your phone for various activities.
How Do Malicious Apps End Up on Google Play?
Social engineering plays a significant role in getting malicious apps onto Google Play. Social engineers use their skills to convince users to download apps with malicious intent. Some red flags that indicate a malicious app include:
- The app’s name copies the name of a real, safe app
- The app uses a sensational tone
- The app offers features and functions that are too good to be true
- The app pushes users to download it quickly
- The app uses fear tactics in its description
- The app promises rewards in exchange for access permissions
- The app uses bad language and poor grammar
- The app has “fake” reviews that push it to a positive rating
Legitimate developers may also use these elements, but typically do not use free stock images or very bright, warm colors. To determine if an app is legitimate, examine everything objectively before clicking the “Install” button. Check if the visual elements look original, if the language is correct and neutral, if the developer has other apps, if the app has reviews, and if the app has a negative reputation online.
How Can You Tell if Your Android Phone Has Malware?
If your phone is infected with malware, you may notice several signs:
- Your device randomly heats up throughout the day, even when not in use
- Your battery drain has worsened suddenly
- You notice unfamiliar apps on your phone
- Your phone is sluggish when in use
- Ads start popping up on your phone’s menus
