This Android app with 40 million downloads ‘robbing’ users

An Android app that has 40 million downloads on Google Play Store has been found making suspicious transactions outside the knowledge of its users. According to report by Upstream’s security platform Secure-D, Snaptube — the app that allows users to download videos from YouTube for offline viewing — has been “delivering invisible ads, generating non-human clicks and purchases, then reporting them as real views, clicks and conversions to the advertising networks that serve them.”
As per the report, Snaptube has generated more than 70 million such suspicious transactions from 4.4 million unique devices in just six months. Secure-D managed to block these transactions that it claims would have cost users up to $91 million in unwanted premium charges. Upstream says that users in Brazil, Egypt, Sri Lanka, Malaysia and South Africa have been the most affected by the attacks which are still ongoing.
