The Anubis banking trojan is a malicious Android malware that poses a significant threat to mobile users and the developers of mobile banking apps. Anubis is an Android banking trojan that was first discovered in 2017. It is designed to target Android devices and steal sensitive financial information, particularly login credentials and personal data related to banking and financial apps. Anubis is distributed through malicious apps, fake updates, or phishing campaigns.
Threats Posed by Anubis to Mobile Banking Apps
- Data Theft: Anubis is primarily designed to steal sensitive information from the user’s device. Information includes login credentials for mobile banking apps and other financial services, such as usernames and passwords.
- Keylogging: The trojan can capture keystrokes made by the user, including login information and other sensitive data entered into mobile banking apps.
- Overlay Attacks: Anubis often employs overlay attacks, displaying fake login screens on top of legitimate mobile banking apps. Users may unknowingly enter their credentials into these fake interfaces, which are then captured by the trojan.
- Accessibility Service Abuse: Anubis can abuse Android’s accessibility services to gain control over the device’s functions and manipulate app interfaces, making it challenging to detect.
- SMS Intercept: The trojan can intercept SMS messages on the infected device, including one-time passwords (OTPs) and transaction verification codes sent by mobile banking apps. SMS intercepts allow attackers to bypass two-factor authentication measures.
- Remote Control: Anubis may establish a connection to a command and control (C2) server controlled by attackers. These server connections enable remote control of the infected device, allowing attackers to execute various commands, including unauthorized transactions.
Mitigating the Threat of Anubis
To protect your mobile banking app and its users from the Anubis banking trojan and similar threats, consider implementing the following security measures:

- Multi-factor Authentication (MFA): Encourage users to enable MFA for their accounts to add an extra layer of security.
- Real-time Monitoring: Implement real-time monitoring to detect and respond to suspicious activities within your app and network traffic.
- Secure Coding: Follow secure coding practices to prevent vulnerabilities in your app’s code, including input validation, data encryption, and secure API communication.
- Third-party Library Review: Carefully review and vet third-party libraries or components used in your app for potential security risks.
- Collaborate with Security Experts: Work with cybersecurity experts to conduct security assessments, code reviews, and penetration testing to identify and address your app’s security weaknesses.
- Incident Response Plan: Develop an incident response plan to respond to security incidents or breaches effectively.
By taking these precautions, you can help safeguard your mobile banking app and protect your users from the threats posed by the Anubis banking trojan and other evolving malware.
