FluBot is a sophisticated SMScomputer virus –specifically a banking Trojan– of global reach which aims to steal private data from Androidsmart phones. Unlike much malware, FluBot has proven exceptionally durable, coming in waves or "campaigns" with each redesign. It masquerades as innocuous messages such as missed calls and deliveries, asking the receiver to click links that download spyware.[1] A variant, TeaBot, has infiltrated official app stores, including Google Play Store, in the guise of a QR-code reader.[2][3][4]
