In January 2024, we reported several vulnerabilities being exploited by the XRY tool from MSAB to get data from Android devices including stock OS Pixels. In April 2024, Pixels shipped a reset attack mitigation we proposed preventing the whole attack vector. We plan to expand it.
Currently, non-Pixel devices are still vulnerable to these reset attacks. In June 2024, Android 14 QPR3 included another feature we proposed providing wipe-without-reboot support for the device admin wipe API. We shipped this early and use it in our duress PIN/password feature.
We also began triggering a full compacting garbage collection cycle in system_server and SystemUI when the device is locked based on info about these attacks. This releases memory for no longer allocated objects to the OS, where our generic zero-on-free feature clears all of it.
In the near future, we plan to ship support for adding a PIN as a 2nd factor to fingerprint unlock to enable users to use a strong passphrase combined with PIN+fingerprint secondary unlock for convenience. We have an initial implementation, but it needs more work before shipping.
