Researchers at Tel Aviv University in Israel found that several Galaxy S8,
Galaxy S9, Galaxy S10, Galaxy S20, and Galaxy S21 phones models didn't store
their cryptographic keys properly, effectively allowing hackers to extract
the information stored in them, which could include sensitive data such as
passwords.

The TrustZone Keymaster Design issues have already been patched by Samsung,
which was notified of the problem promptly after it was discovered. The
first fix started rolling out with the August 2021 security patch and a
subsequent vulnerability was addressed with the October 2021 patch.

However you might want to consider updating your Samsung phone if it on an
older security patch. If Samsung has stopped supporting your device, you may
have to rely on third-party custom ROMs with updated security.
