Around 100 million Samsung smartphones were affected by a vulnerability in the cryptographic security environment of the South Korean brand, which exposed hardware-protected user keys to cyberattacks, although the company has already fixed it.

The bug, discovered by researchers at Tel Aviv University in Israel, centers on Samsung’s implementations of the TrustZone operating system, which runs parallel to Android on its mobile devices.

As the authors report in the study, the cryptographic design and implementation of a hardware-supported system to protect Samsung mobile keys using trusted execution environments had “severe design flaws.”

These issues affected the latest flagship families released by Samsung, including the Galaxy S21, S20, S10, S9, and S8 series, which came to market between 2021 and 2017 and are direct predecessors of Samsung. the Galaxy S22 this year.

Through reverse engineering techniques and analysis of the code structure of Samsung’s TrustZone implementation, Tel Aviv University researchers tested the feasibility of three attack techniques that expose cryptographic information on smartphones.

After knowing the vulnerabilities investigated, Samsung released a security patch to solve the problem of its smartphones in August of last year, which was completed with a subsequent update in October to finish protecting its devices.

Marcos Galperin, founder of the electronic commerce company Mercado Libre, assures that bitcoin has turned out to be the “better store of value than gold”. This was announced by the Argentine billionaire after a query made by Twitter users who asked him if he had bitcoin.

However, he added that even when cryptocurrencies have taken a position in the market, he does not believe that they will replace fiat currency, due to what he calls the high “cost of energy required to process his transfers.”

Galperin, who has an equity valued at USD 7.7 billion, according to Bitcoin.com, is betting on “quantum computing” as an alternative to solve the challenge of high energy costs that in his opinion he considers affects the bitcoin network.

Bitcoiners in opposition

Faced with this assertion, responses were generated from many bitcoin users, such as Martín Morando, who explained that Galperin’s mining understanding may not be so accurate. “The energy cost is not a problem, it is part of the package! In addition, most of the energy used is renewable.”

On the other hand, other users like Mathías Walkoski, assured that quantum computing “could cause the cryptographic keys of BTC to be hacked.”
