TrickyStore is an Android device integrity emulator and keystore attestation spoofer. It functions as a framework to intercept keystore calls and provide modified certificate chains and security metadata to bypass hardware attestation requirements.
The project enables the injection of hardware keyboxes and the modification of key attestation certificates to simulate a secure root of trust. It allows for the overriding of security patch levels and operating system versions to mask a device's identity and state from third party applications.
The system includes capabilities for application-specific attestation filtering, asymmetric key generation, and the persistent storage of attestation keys to maintain consistency across device reboots. It can toggle between modifying existing certificates and generating new chains based on a target configuration list.
