Malicious Android apps posed as Angry Birds, Assassins Creed, Cut the Rope and other popular titles in a scam that used premium rate text messages from unwitting consumers to defraud them of £27,850.
The attack took place at the end of last year and affected 1,391 mobile numbers in the UK.
Regulator PhonepayPlus received just 34 complaints, however, all those consumers that lost money will automatically be refunded.
It is understood the most that any individual is thought to have lost is £80.
The attack gained access to users' phones when they were downloaded and then sent three premium rate text messages each time the application was opened.
Although Google removes malicious apps from the Android Market, it doesn't vet apps before they are initially uploaded.
A Latvian firm has been ordered to pay the fine of £50,000, as well as refund the £28,000 to the mobile phone users affected.
