Pornographic images were found on scores of children’s game apps which were in the Google Play store, caused by a malicious code called “AdultSwine”.
Researchers at Check Point found that 63 apps were affected.
Check Point said AdultSwine caused pornographic images to pop up during the children’s games, including in a car-racing game named after the Disney cartoon character Lightning McQueen, which according to Google data had been downloaded at least 500,000 times.
In addition to displaying pornographic content, AdultSwine can also show pop ups that state a virus has infected the device, prompting the user to download another app claiming to be able to remove it.
A security system called Google Play Protect is supposed to defend customers using Google’s Android operating system from malicious codes by scanning apps for malware.
