Banking Trojans and Financial Theft

Banking trojans like Datzbro, Cerberus, and Hydra have stolen millions from Android users by:

• Intercepting SMS two-factor authentication codes
• Overlaying fake login screens on banking apps
• Taking screenshots of sensitive information
• Recording keystrokes to capture passwords

GrapheneOS Protection: App sandboxing prevents apps from accessing other apps' data. Network permissions block unauthorized connections. Hardened memory allocator prevents many exploitation techniques used by trojans.

Zero-Click Exploits

Zero-click exploits like those used by NSO Group's Pegasus spyware can compromise devices without any user interaction through:

• Memory corruption exploits
• Baseband processor vulnerabilities
• Social engineering attacks

GrapheneOS Protection: Hardened memory allocator blocks memory exploitation. Reduced attack surface eliminates many vulnerability vectors. Baseband isolation limits attack scope. Regular security updates patch known vulnerabilities.

Corporate Tracking and Data Harvesting

Google, Facebook, TikTok, and thousands of apps constantly track your:

• Precise GPS location history
• App usage patterns and screen time
• Contacts and social connections
• Web browsing history
• Device identifiers for cross-app tracking

GrapheneOS Protection: Zero telemetry means no data sent to Google. MAC address randomization prevents WiFi tracking. Per-app network controls block unauthorized connections. No advertising identifiers.

SIM Swapping Attacks

Attackers convince mobile carriers to transfer your phone number to their SIM card, then use it to bypass SMS two-factor authentication and take over accounts.

GrapheneOS Protection: Use authenticator apps (TOTP) instead of SMS-based 2FA. Enhanced security features make the device itself harder to compromise even if SIM is swapped.

Public WiFi Attacks

Attackers on public WiFi networks can intercept unencrypted traffic, perform man-in-the-middle attacks, or serve malicious content.

GrapheneOS Protection: Enforced HTTPS connections. MAC address randomization per network. Enhanced WiFi privacy controls. Works seamlessly with VPNs for additional protection.

Supply Chain Attacks

Malware pre-installed on devices by manufacturers or carriers before you even buy them - a growing problem with Android phones.

GrapheneOS Protection: Clean installation removes all pre-installed bloatware and potential backdoors. Open-source code can be audited. Verified boot ensures system integrity.

Social Engineering and Phishing

While no OS can fully protect against user error, GrapheneOS provides additional safeguards:

• Enhanced security indicators in the Vanadium browser
• No pre-installed apps that could be impersonated
• Clear permission prompts that can't be spoofed
• Sandboxing limits damage even if malicious app installed
