Irish Android and iPhone have been put on high alert by Facebook after they US social media giant discovered a data hack related to around 400 apps.
Facebook says it has pinpointed the apps that appear to have been stealing private logins from smartphone users. To make matters worse, these dangerous applications were found listed on the official Google Play Store and Apple App Store marketplaces which means it's highly likely they may have been installed on a large number of devices.
The dangerous apps managed to sneak onto the Play Store and App Store by disguising themselves as popular services such as photo editors, mobile games and VPN services. Once installed they then set about trying to access private data by suggesting that users need to sign in, via their Facebook account, to gain access to features.
