After Sophos, a cyber security company that makes security apps wrote a blog post about it, Google has deleted 22 apps from the Play store. The apps were deemed malicious — like a computer or mobile virus — and had a backdoor built into them that helped the apps do ad-fraud. Collectively these 22 apps were downloaded by over 2 million times before they were deleted.
Sophos in its investigation found that the apps linked to Andr and Clickr-ad network. The security company wrote that the this “is a well-organized, persistent malware that has the potential to cause serious harm to end users, as well as the entire Android ecosystem” because “these apps generate fraudulent requests that cost ad networks significant revenue as a result of the fake clicks.”
