hi
I tried the POC test with the S21, but it didn't work normally.
As a result of keybuster_test execution, all but one failure are displayed as success.

But when I run poc.sh, poc_rsa.sh it fails on the first step and does not proceed.

If the device is patched (e.g. patch level greater than November 2021) then the PoC will not work since Samsung fixed the issues after our responsible disclosure.

From a quick look at the logs, it seems that your device is indeed patched since the command that fails is the import of v15 blobs (the patch completely removes the legacy key blob implementation).
