The Herodotus Android banking Trojan is emerging as a key threat, spreading through SMS phishing campaigns. Victims are lured into downloading malware from unofficial sites, bypassing Google's Play Store safeguards.
Phishing Tactics and Infection
After installation, Herodotus leverages critical permissions like Accessibility to overlay fake screens on legitimate banking apps. This allows it to capture sensitive data and execute fraud in real-time. The Trojan's tactics include sophisticated evasion techniques that emulate human behavior, challenging traditional security tools.
According to research by Pradeo, these human-like interactions—random typing and subtle screen movements—make Herodotus difficult to detect. Some antivirus solutions fail to identify it since it activates harmful behavior only post-installation.
Necessary Security Measures
Pradeo advises deploying robust Mobile Threat Defense (MTD) systems as a countermeasure. Such systems can block phishing links, identify unauthorized app installations, and manage sensitive permission requests. They can also detect UI overlays and network activities tied to suspicious behavior, crucial for protecting enterprise environments.
For businesses, adopting specialized MTD solutions is critical to shield sensitive financial data and ensure secure mobile interactions.
