If you have these apps, delete them Right Now!
This is a warning about some malicious apps which can give you a huge phone bill. Delete it right now!
After a number of common applications have been found to run large bills on victims' devices, Android users were encouraged to check their security settings.
The Pradeo security firm has noticed that many applications with hundreds of thousands of downloads are actually called "fleeceware" which means rare users have been linked to premium services, leaving them with substantial additional costs.
A malicious bot called the Joker corrupted the applications, which the developers and unknown victims could not identify.
A total of six joker-infected applications, including security apps, scanners, SMS services, host fonts and game platforms, accounted for nearly 200,000 installations, Joker-infected.
One of the applications, Convenient Scanner 2, contains more than 100,000 installs alone, which can catch thousands of users.
Roxanne Suau, a writer from Pradeo's wrote in a blog post;
"Joker is a malicious bot (categorized as Fleeceware) which main activity is to simulate clicks and intercept SMS to subscribe to unwanted paid premium services unbeknownst to users,"
"By using as little code as possible and thoroughly hiding it, Joker generates a very discreet footprint that can be tricky to detect."
Pradeo notes that now all infected applications are deleted from Google Play, but that they will remain installed on any person's devices. The company urges users to immediately delete any of the apps affected.
The report comes soon after a separate report says that many Android phones can store "undeletable" files and apps after a number of widespread attacks. Kaspersky data shows that a large variety of Android devices affected by cybercrime can still contain malicious files or items without any knowledge of user.
