Dozens of Android camera applications, some of them with over 1 million installs on the Google Play Store, were serving malicious ads and fake update prompts while also making sure that they won't be uninstalled by hiding their entries from the application list.
Lorin Wu, a mobile threats analyst for Trend Micro, sorted
these malicious apps in two different categories: some of them were variations of the same camera application designed to beautify photos, while the other kind allowed their users to apply photo filters on their snapshots.
These apps have all been removed from the Google Play store by now, but not before they were able to amass millions of installations (some of them most probably fake).
All of them were also obviously connected to each other given that they were sharing various design components such as the screenshots added to their Google Play entries.
