Researchers at Wandera, a mobile security company, discovered the two apps on Google’s store. The first, Sun Pro Beauty Camera, had over one million downloads, while the second, Funny Sweet Beauty Selfie Camera, had over 500,000 downloads.
The apps were found to serve up intrusive out-of-app ads, which are not only a huge annoyance but may also brick devices, drain their batteries, and in some cases infect them with more malicious forms of malware.
