Fake photo editor apps hiding adware found on Google Play with a total of 3.5M downloads
A group of 29 fake apps was found on Google Play. When downloaded, the apps can open web browsers on their own. They also pop up random advertisements triggered by a number of user interactions on a compromised phone including anytime the phone is unlocked or plugged into a charger. All of the apps appear to masquerade as photo editors.
The apps have already been downloaded 3.5 million times from the Google Play Store. They are barely functional except for showings ads.
“Instead of any usable app functionality, though, the user is simply bombarded with out-of-context interstitial ads,” says a report from the White Ops Satori Threat Intelligence and Research Team.
OOC advertisements pop up each time the user unlocks their phone. Each time an infected device is unlocked, plugged into a charger, switches wireless networks, advertisement pop up on the home screen,
What are OOC Advertisements?
OOC advertisements, or cause out-of-context ads, are types of advertisements that are shown to the viewer using no particular type of targeting. It means an advertisement is shown to the user with no basis for knowing if they would have an actually have an interest or need for the featured product.
The opposite of OOC ads are contextual advertisements. The ad is shown to the viewer using ad targeting based on previous viewer behavior on websites, social media, demographics information, and even in-store purchases. Information for targeting contextual advertising is often taken from cookie tracking, contact lists, and credit card partners. A targeted advertisement is more likely to be of interest to the viewer because they indicated an interest through past purchase history or online activity.
Annoying advertisements are not the only sign that is a phone infected with adware, malware, or another malicious app. Additional signs of a compromised device include random noises during calls, a phone that’s running at hot temperatures, a short battery life, high data usage, apps that won’t close, apps that don’t function as expected or outbox messages appear that you did not send.
The fake app with the lowest number of downloads (5,000+) was Blur Photo Editor. A few of the other fake apps, like Square Photo Blur, had over 500,000 downloads each
