Android and iPhone users have been issued with a warning after an abundance of mobile applications have been found to contain information stealing malware.
Facebook say that they have pinpointed more than 400 apps which appear to be stealing private login information from smartphone users - and to make matters worse, these dangerous applications have all been listed on either the official Google Play store of Apple App store.
This means that it's highly likely that the apps have been installed on a large number of devices worldwide.
