Ryzen cpus vulnerabilities take amd by surprise

Today we had told you about the 13 security flaws discovered in the AMD Ryzen processors and the consequences that this could have in terms of privacy and theft of data from users who own any of these CPUs.

Security flaws discovered in Ryzen, Threadripper and EPYC processors

An Israeli cybersecurity investigation firm with six employees (CTS Labs) said Tuesday that it had found flaws in the AMD microprocessors. When this report was released, AMD shares fell to $ 11.10, then rebounded to 11.80 throughout the day.

CTS executives told Reuters they had shared their findings with some clients who pay the firm for the proprietary investigation into vulnerabilities in computer hardware. CTS declined to identify its customers or to say when they had been provided data on these vulnerabilities.

On Friday and Monday, AMD's short sale of shares increased by about 15 million shares, according to S3 Partners, a financial analysis firm. This brought global short-term interest in the chipmaker of approximately 180 million shares, most since at least 2010. '' In the past few days there has been a short-term spike in sales that was completely out of the norm, ” said Ihor Dusaniwsky, head of research at S3 Partners. In conclusion, many shareholders already knew what was going to happen as soon as the news about Ryzen's vulnerabilities became known.

AMD said the report took him by surprise.

'' CTS Labs was a company unknown to AMD and we find it unusual for a security company to publish their investigation to the press without providing a reasonable period of time for us to investigate their findings, ' AMD said in a note to clients in your website.

New York cybersecurity company Trail of Bits told Reuters that it had verified CTS's findings, and corroborated that the vulnerabilities are true.

Recall that Ryzenfall, Masterkey, Fallout and Chimera vulnerabilities affect all Ryzen, Threadripper and EPYC processors.
