https://safirsoft.com Pluto, Microsoft's new security chip will finally be tested

AMD is the first CPU manufacturer to incorporate a Microsoft-designed chip into its products.

In November 2020, Microsoft built Pluton, a security processor designed to thwart some of the most sophisticated types of hacking attacks. . On Tuesday, AMD announced that it will integrate the chip into future Ryzen processors for use in Lenovo ThinkPad Z series laptops.

Microsoft previously used Pluto to secure Xbox Ones and Azure Sphere microcontrollers against attacks involving physically accessible people, opening hardware chests, and hacking devices that circumvented security protections. These hacks are usually carried out by device owners who want to run unauthorized games or software to cheat. They are designed to steal encrypted keys or other sensitive items. Secrets While many systems already have trusted platform modules or protections such as Intel Software Protection Extensions to protect this data, secrets are vulnerable to many types of attacks.

ReadingIntel SGX failed again. Such a physical attack involves laying wires that collide with the communication between the TPM and other components of the device and extracting secrets that pass between devices. Last August, researchers discovered an attack that took just 30 minutes to extract a BitLocker key from a new Lenovo computer that already uses TPM for full disk encryption, password-protected BIOS settings, and UEFI SecureBoot. The hack - which worked by sniffing the communication between the TPM and the CMOS chip - showed that locking a laptop with the latest defense system isn't always enough. A similar attack revealed three months later showed that a vulnerability (now fixed) could be used on Intel CPUs to break all security measures, including those provided by BitLocker, TPM, and anti-copy restrictions. Attacks called Specter and Meltdown have repeatedly emphasized the risk of extracting malicious passwords directly from the CPU, even when secrets are stored in Intel SGX.

Pluto's new approach to design fixes all these mysteries. It integrates directly into the CPU, storing encryption keys and other secrets in an enclosed garden completely separate from the rest of the system. Microsoft said that the data stored there cannot be deleted even when the attacker has malware installed or has a personal computer, as it is unique. key or hut. SHACK helps ensure that keys are never placed outside of protected devices, even for Pluton's operating system. Pluto will also be responsible for providing automatic firmware updates through Windows Updates. With hardware and software integration, Microsoft expects Pluto to integrate security patches as needed.

To avoid everything malicious and unauthorized as possible, says Joseph Fitzpatrick, hardware hacker and software security researcher at SecuringHardware.com. Pluto is the hardware path to get there. p> https://safirsoft.com Pluto, <b>Microsoft's</b> <b>new</b> <b>security</b> chip, <b>will</b> <b>finally</b> arrive.

Microsoft said the ThinkPad Z13 and Z16 models, which use Pluton as a TPM, help protect Windows Hello credentials by further separating the credentials from attackers. </ p></div><br><div class=Tags: pluto, microsoft's, new, security, chip, will, finally, tested
