New Perseus Android Banking Malware Monitors Notes Apps to Extract Sensitive Data

Cybersecurity researchers have identified a new family of Android malware called Perseus, designed for device takeovers and financial fraud. It utilizes Accessibility-based remote sessions for real-time monitoring and interaction with infected devices, particularly targeting Turkey and Italy. Perseus monitors user notes to extract personal or financial information and is distributed through dropper applications via phishing websites. It expands on the codebase of previous malware like Phoenix and employs disguises as IPTV services to reduce user suspicion. Once operational, it performs overlay attacks and captures keystrokes to steal credentials from financial applications. The malware allows operators to issue commands through a command-and-control panel, enabling various malicious actions, including capturing note content and initiating remote visual streams. Perseus also conducts environment checks to evade detection and ensure it operates on legitimate devices.

New Android malware hiding in streaming apps to spy on users’ personal notes

Researchers have discovered a sophisticated malware called Perseus that targets Android users by disguising itself within television streaming applications to steal sensitive information, including passwords and banking details. This malware, reported by ThreatFabric, primarily affects users in Turkey and Italy and is based on the leaked code of previous Android banking trojans, particularly Cerberus. Perseus masquerades as IPTV service apps, often downloaded from unofficial sources, and employs overlay attacks and keylogging techniques to capture user credentials. It specifically targets personal note-taking applications like Google Keep, Evernote, and Simple Notes to extract sensitive information stored within them. The malware landscape is evolving, with new threats like the banking trojan Herodotus and the Crocodilus variant, which can manipulate contact lists. Users are advised to be cautious when downloading applications from unofficial sources.

Massiv: When your IPTV app terminates your savings

Massiv is an Android banking Trojan that disguises itself as legitimate applications, primarily targeting users in southern Europe. It is distributed through side-loading and is capable of remote control over infected devices, enabling Device Takeover attacks that can lead to unauthorized banking transactions. Massiv often masquerades as IPTV applications to attract users seeking online television services. The malware employs overlay functionality to create deceptive screens, keylogging to capture sensitive information, and SMS/Push message interception. It can monitor applications on infected devices and present fake overlays to prompt users for sensitive data. Notably, it has targeted the Portuguese government application gov.pt and connects with Chave Móvel Digital, a digital authentication system, to access victims' banking accounts. Once it captures sensitive data, Massiv allows operators remote access to the device using Android’s AccessibilityService, facilitating real-time observation and manipulation of the user interface. It communicates over a WebSocket channel and supports screen streaming and UI-tree modes for enhanced control. Massiv's distribution includes malware droppers that initially do not contain malicious code but open a WebView to an IPTV website while the actual malware operates in the background. This tactic has increased in recent months, particularly in Spain, Portugal, France, and Turkey. Indicators of compromise include specific SHA-256 hashes and package names associated with the malware. The bot commands allow operators to perform various actions on the infected device, such as clicking coordinates, installing APKs, and showing overlays.
