Marcher Malware: A Banking Trojan Targeting Android Devices
With SpyHunter
Marcher Malware Overview
Marcher is a highly sophisticated banking Trojan that primarily targets Android users. Once installed, the malware requests extensive permissions, including device administrator rights, which allow it to modify system settings and ensure persistence.
One of the core functionalities of Marcher is its ability to overlay legitimate applications with fraudulent phishing pages. This technique enables cybercriminals to steal login credentials, payment details, and other sensitive data. Marcher has been observed impersonating popular banking apps and financial services, tricking users into entering their information into malicious forms.
Beyond credential theft, Marcher is capable of intercepting SMS messages, allowing attackers to capture one-time passwords (OTPs) and two-factor authentication (2FA) codes. This greatly increases the likelihood of unauthorized access to banking and financial accounts.
Additionally, Marcher can:
- Prevent the device from going to sleep
- Modify and delete files from external storage
- Collect information about Wi-Fi networks and device location
- Read, send, and delete SMS messages
- Make phone calls without user interaction
These capabilities make Marcher one of the most dangerous Android malware strains, with the potential to cause severe financial and privacy-related damages.
