Back in October 2015 security firm lookout found several applications live in the Google Play Store written by the developers behind the Brain Test malware family, these apps had hundreds of thousands of downloads and had at least a four star average review score.

 This wasn’t the first time that the security firm had discovered malware hidden in brain training apps, just one month before Google had removed two Brain Test samples after a report by Checkpoint.
