Flubot: the evolution of a notorious Android Banking Malware
Flubot is an Android based malware that has been distributed in the past 1.5 years in Europe, Asia and Oceania affecting thousands of devices of mostly unsuspecting victims. Like the majority of Android banking malware, Flubot abuses Accessibility Permissions and Services in order to steal the victim’s credentials, by detecting when the official banking application is open to show a fake web injection, a phishing website similar to the login form of the banking application. An important part of the popularity of Flubot is due to the distribution strategy used in its campaigns, since it has been using the infected devices to send text messages, luring new victims into installing the malware from a fake website. In this article we detail its development over time and recent developments regarding its disappearance, including new features and distribution campaigns.
