Unpleasant news for owners of Samsung Galaxy S7 smartphones. Experts have discovered a vulnerability in the gadgets' microchips that allows attackers to spy on unsuspecting users.According to the data presented by researchers from the Technical University in Graz (Austria), tens of millions of Samsung mobile devices were at risk of being hacked by cybercriminals. Experts have proved that Galaxy S7 smartphones are prone to Meltdown vulnerability. Recall that previously it was thought that the company's devices are protected from this breach. Michael Schwartz - one of the experts who discovered the problem, said that other mobile devices from Samsung may also be exposed to the vulnerability. The team of researchers plans to check other models of smartphones of the South Korean giant and publish reports at the Black Hat security conference in Las Vegas. According to research company Strategy Analytics, Galaxy S7 smartphones are currently used by about 30 million people. All of them may be victims of cybercriminals. At the same time, Samsung representatives assure that they released patches to protect the Galaxy S7 from Meltdown back in January and July. Moreover, since then, there have been no proven cases of Meltdown being used to attack this or any other Samsung smartphone model.
