Samsung fixes hardware key security vulnerability affecting hundreds of millions of Android devices

SamMobile reports that although Samsung can always provide security updates for its sizable Android mobile devices before Google officially releases a fix.

However, Samsung smartphones sold over the past few years have been found to have a factory-built security flaw that allows hackers to easily extract sensitive information, including passwords. Researchers at Tel Aviv University in Israel pointed out that the problem is that the Galaxy S8/S9/S10/S20/S21 series models fail to properly store their encryption keys.

In a recent report ( PDF ), Alon Shakevsky, Eyal Ronen, and Avishai Wool detail how they circumvented security measures on Samsung devices. The article involves many technical terms of security technology, which requires readers to have a certain knowledge base.

Fortunately, consumers don’t need to worry too much about this, because the researchers notified Samsung in a timely manner, and the company has already completed the fixes for the above-mentioned security risks.

It is reported that the first fix will be pushed from the August 2021 security patch, and then all the fixes will be completed in October. If you are still using an older version, please update to the latest supported version as soon as possible.

Finally, if the device is out of Samsung’s official support period, consider switching to a third-party custom ROM that is still providing security updates.
