Summary
Hardware key attestation lets an Android app prove to its backend that a key lives in secure hardware on a locked, verified device. It is also the wall that stops a security analyst working on a rooted phone. This article opens the mechanism from the analyst's chair, from the certificate chain and the attestation extension down to the root of trust, then shows a simple bypass that never touches the secure hardware. We relay the attestation to a clean device and splice a genuine chain back into the target app with a Frida hook. A companion repository ships the validation backend, the demo apps and the instrumentation, so the whole setup can be run and inspected rather than taken on faith.
