Researchers from cybersecurity firm Check Point warned recently of a widespread malware which may have affected 36.5 million Android users at most.
The malware, dubbed "Judy," is an "auto-clicking adware which was found on 41 apps developed by a Korean company," Check Point said in their latest blog.
Once installed on a phone, the apps can generate large amounts of fraudulent clicks on advertisements and therefore make revenues for the perpetrators behind it.
"Judy" was discovered on Google Play, Google's official app store, and believed to be possibly the largest malware campaign found on the platform, Check Point said.
The spread of the malicious apps is estimated between 4.5 million to 18.5 million downloads, while the actual figure remains unknown.
After Check Point notified Google about this threat, the apps were swiftly removed from the Google Play store.
