A DODGY app with over a million downloads is a bit of a headache for Android users.
The newly discovered adware, disguised as a PDF reader, delivers annoying full-screen ads that pop up randomly.
According to cyber security company Malwarebytesthat identified the nasty download, the ads appear even when the app isn’t being used.
This makes it very difficult to identify and remove the source of the pop-ups that users are often bombarded with.
Every time an ad is shown, the crooks behind the app make a small amount of money.
These earnings could add up to a lot of money if over a million people downloaded the fake software.
Once installed, the app named “PDF Reader – Documents Viewer” keeps beeping whenever the infected phone is locked.
When the phone’s owner unlocks it to see what all the fuss is about, an annoying full page pops up.
After the first ad is displayed, another ad follows shortly after in the form of a video.
After those initial annoyances, ads keep coming.
The app’s developers cleverly designed it to evade detection, Malwarebytes’ Nathan Collier wrote.
“It takes a few hours for the PDF app to show ads.
“This long delay is meant to make it harder to figure out which app is causing the ads.
“For example, full-screen ads displayed immediately after installation would likely result in a quick uninstall.”
The app has been available in the Google Play Store since November 2021.
According to its listing, it has over a million downloads.
Adware earns crooks a quick buck by displaying multiple indecent online ads on a person’s phone without their consent.
The software is usually disguised as a useful app on the Google Play Store to hide its nefarious purpose.
Google has banned such apps from its store and has implemented controls to prevent adware and other malicious downloads from appearing there.
However, many still slip through the cracks, and hundreds, if not thousands, flock to the store each year.
To avoid getting caught, make sure your Andriod software is up to date and think twice before you click a download.
It’s also worth manually scanning downloaded files for viruses before opening them.
