A new Android banking Trojan named Massiv has been discovered, posing a significant threat to mobile banking users. This malware allows remote control of infected devices and enables Device Takeover attacks, leading to fraudulent transactions from victims' accounts. Massiv is distributed through side-loading, often masquerading as IPTV applications. It features overlay functionality, keylogging, and SMS/Push message interception to steal sensitive data. The malware has targeted government applications and digital identity wallets, particularly in Portugal. Massiv supports screen streaming and UI-tree modes for remote control, bypassing screen capture protections. The trend of malware masquerading as IPTV apps is increasing, exploiting users' willingness to install from unofficial sources.
