on GitHub

TEESimulator 3.0 is a significant update focused on powerful new configuration options, major improvements to stealth, and enhanced stability.

✨ Highlights & New Features

• 🎯 Per-App Security Patch Configuration: Gain ultimate control by setting security patch levels on a per-package basis. Define a global default in security_patch.txt and override it for specific apps like [com.google.android.gms]. Moreover, your configuration is now alive! Use the today keyword to always report the current date, or create rolling dates with templates like YYYY-MM-05. Be sure to check README for more details.
• 🕰️ Full Software Emulation on Android 11: We've implemented a complete, software-based key generation and attestation flow for the legacy IKeystoreService API, bringing full emulation capabilities to older devices.

🛡️ Stealth & Evasion Upgrades

• ⛓️ Consistent Certificate Signatures: Say goodbye to a major detection vector in icu.nullptr.nativetest. Patched certificates are now cached, ensuring that every request for a key returns a byte-for-byte identical certificate, just like a real TEE.
• 🔑 Authentic Device Properties: To appear more genuine, the simulator now sources and uses your device's real verifiedBootHash and moduleHash, moving away from placeholder values.
• 📜 Structurally Sound Certificates: The patching logic has been rewritten to be less intrusive. It now modifies the attestation extension in-place, preserving the original order of other extensions and preventing duplicates to avoid suspicion.

🐛 Bug Fixes & Reliability

• ✅ Robust Crypto Engine: Fixed critical crashes related to cryptographic provider conflicts. The signing logic is now more explicit and the KeyBox parser is more resilient against malformed files.
• ➡️ Improved Compatibility: Resolved a native crash on Android 11 devices.

🚀 The Road Ahead

Our work to fix detection vectors and provide full support for TEE-broken devices and Android 10/11 is ongoing. We welcome your feedback! Please report any issues or contribute a pull request on our GitHub.
