Beware of Malicious Mobile Apps | McAfee Blog

With the surge in the usage of mobile phones, there has been a concurrent increase in malicious activities targeting these devices. One common technique used by hackers is to corrupt legitimate applications. Android devices, in particular, see increases in malware targeting mobile phones year by year. According to McAfee 2023 Consumer Mobile Threat Report, Clicker Malware, a type of malware that runs in the background, spread through deceptive applications masquerading as system utilities such as flashlights and task managers in 2022. Other types of malware also became rampant, such as Dropper, Hidden Ads, and FakeApp. Almost all new mobile malware targets Android’s operating system.

Steps to Secure Your Device

While the instances of smartphone malware are relatively few compared to what is seen with desktop or laptop PCs, being aware of the threat is the first step towards safeguarding yourself and your data. Thorough research of applications and their publishers is crucial. It is always safer to install applications that have high user ratings, are widely used, or have been recommended by your friends or acquaintances.

Getting apps from a reputable and well-established market is also advisable. Android users can prevent the installation of non-market apps by deselecting the “Unknown Sources” option in their device’s application settings menu. However, if this option isn’t available, it means that your mobile provider has automatically blocked applications from unknown sources.

Watching the Permissions

As you install different applications, you will notice a list of permissions for services that can access the hardware and software components on your device. You need to stay vigilant and check these permissions. If you suspect any foul play, for instance, a game or alarm clock app asking for your contact details or any other sensitive data, refrain from installing the app. In case you have any doubts regarding the data the app is accessing, the best course of action is not to install it.

Another important step that you can take is installing antivirus software on your phone. Doing this before adding any other apps to your new mobile device can help to increase its security.

Additional Mobile Security Measures

Aside from the aforementioned steps, there are several other security measures that you can employ to protect your mobile device. A very elementary yet highly efficient method is setting up a strong password for your device. Make sure to choose one that cannot be easily guessed. Regularly updating your phone’s operating system and apps is also crucial since updates usually come with security fixes for vulnerabilities that hackers might exploit.

Next, be cautious when clicking on links in text messages, emails, or social media. Verify the sender’s legitimacy and avoid downloading attachments or clicking suspicious links. These may lead to phishing websites, which aim to deceive you into revealing sensitive information, or malware downloads that can compromise your device’s security.

One more thing to be wary of is the Wi-Fi networks that your device connects to. Public Wi-Fi networks are often unsecured and can provide an avenue for hackers to steal information. When connecting to such networks, it’s best to use a VPN (Virtual Private Network) to encrypt your data and keep it safe from prying eyes. Furthermore, always be cautious about the information you share online; avoid posting sensitive data such as your address, phone number, or personal identification number.

Recognizing Malicious Mobile Apps

Recognizing malicious apps requires vigilance and a keen eye. Malicious apps often masquerade as popular apps, baiting users into downloading them. They often have strange names, with spelling or grammatical errors. Another tell-tale sign is when the app asks for unnecessary permissions that are not needed for it to function. If you find an app asking for permission to access your location or contacts when it has no need to, then it might be malicious.

Finally, note the publisher of the app. Malicious apps often come from unknown or suspicious sources. Genuine apps come from reputable companies that you can trust. Check the reviews and ratings of the app, as they often indicate the app’s legitimacy. Remember, it’s always better to err on the side of caution regarding your mobile device’s security.
