Auto-starting malware that is capable of concealing itself
Although the apps contain malware, all of these apps still managed to make it onto the Play Store and bypass Google’s defences. However, McAfee has now shared its findings with Google, which has since removed them. You will still need to delete them from your Android phone yourself, though.
Although it is usually safe to download and install an app without opening it, this is not the case with these apps. When you install any of these apps on your devices, they will automatically launch the HiddenAds malware and begin operating in the background.
These harmful apps can also conceal themselves to prevent users from detecting and removing them. For example, they alter their icons to resemble the Google Play icon that people are familiar with and rename themselves to ‘Google Play’ or ‘Settings.’
There are several ways that the HiddenAds malware applications display ads to their victims. They are displayed in full-screen and are very intrusive. In addition to this, they also try to get users to run an app whenever they install, uninstall or update any other apps on their devices.
The cybercriminals used Facebook as a means to promote their new malware.
All of these apps avoided Google’s security measures and ended up on the Play Store. As a result, their creators were able to make Facebook pages for each app and promote them through the social platform. Even though these links may lead to apps with malware, Facebook doesn’t view Play Store URLs as malicious.
Cybercriminals often take advantage of free services to attract victims to their malware and anyone can create their own Facebook Business account and business page.
Protecting yourself from the HiddenAds malware
- Check that none of the above-listed apps are installed on your Android smartphone or tablet.
- If so, uninstall them immediately.
- Consider utilising a legitimate antivirus tool/application on your Android device to remove any malware that may be left behind.
- Ensure Google Play Protect is enabled on your devices – this is a great way to scan the apps installed on your smartphone for malware and will notify you if you’re about to install a suspicious app.
- Only download apps from the Google Play Store and not apps from unknown sources.
As the HiddenAds malware is still in development, and its creators are also developing new versions, we may see other malicious applications using it in the future, according to McAfee.
