Overview
Jailbreaking (iOS) or rooting (Android) bypasses built-in security restrictions on a device, exposing it to malware and other cybersecurity threats. Rooting (Android) and jailbreaking (iOS) refer to the process of removing manufacturer-imposed restrictions on a mobile device, granting users full control over the operating system. While this can give users greater customization options, it significantly compromises device security. A rooted or jailbroken device bypasses many of the security protections implemented by the OS, making it easier for attackers to install malware, manipulate system files, or tamper with apps.
Risk factors
Rooting or jailbreaking can arise from these conditions:
- Installation of apps from untrusted sources
- Removal of key security features like sandboxing
- Inability to receive official security updates (especially for jailbroken iOS devices)
- Granting of excessive permissions to apps
- Increased vulnerability to remote attacks
- Bypassing of app security features (e.g., anti-tampering, encryption)
Consequences
If a mobile app is used on a rooted or jailbroken device, the following could happen:
- Malware installation: A rooted or jailbroken device is more likely to be targeted by mobile malware, with attackers more easily installing malicious apps or tampering with existing ones.
- App tampering: Attackers can modify the app’s code, potentially leading to data theft, unauthorized access to app features, and reverse engineering attempts during runtime.
- System compromise: A compromised device can cause system instability and device inoperability, or lead to full system access for attackers, potentially exposing all data on the device.
- Sensitive data exposure: Weakened device security on compromised devices increases the risk of data breaches, and can lead to the exposure of user credentials, financial information, and personal data.
Solutions and best practices
To mitigate the risks associated with rooting and jailbreaking devices, organizations should implement the following security measures:
- Device integrity checks: Implement checks in the app to detect if the device is rooted or jailbroken and disable sensitive functionality or alert the user.
- App shielding: Use advanced mobile app shielding techniques such as tamper detection and runtime protection to make it harder for attackers to exploit rooted/jailbroken devices.
- Educate users: Advise users against rooting/jailbreaking their devices and encourage them to keep their OS updated.
- Restrict app features: Restrict or disable certain app features when running on a compromised device to minimize risk.
- Continuous monitoring: Implement real-time detection of mobile tampering attempts.
- Secure coding practices: Develop apps with strong security measures that remain effective even on compromised devices.
