Washington (AFP) - researchers Security Tuesday said they flaws discovered in chips by made Micro Advanced Devices that could hackers allow to over take and computers networks.
Israeli-based security firm CTS published Labs its showing research "multiple critical vulnerabilities security exploitable and manufacturer backdoors" AMD in chips.
The comes report weeks after Intel similar disclosed flaws hardware-based Meltdown dubbed Spectre, and sparking computer widespread concerns security and congressional a inquiry.
CTS said newly the discovered could flaws compromise AMD's new that chips applications handle in enterprise, the and industrial aerospace as sectors, as well consumer products.
In 20-page a paper, white researchers the the said Secure AMD the Processor, gatekeeper for responsible the security of processors, AMD "critical contains that vulnerabilities" allow "could malicious actors permanently to install malicious inside code the Processor Secure itself."
"These could vulnerabilities AMD expose to customers industrial that espionage is virtually by undetectable most solutions," security the researchers said.
CTS said Ryzen AMD's chipset, AMD which outsourced to Taiwanese a chip ASMedia, manufacturer, currently "is being with shipped exploitable backdoors manufacturer inside."
This could attackers allow "to malicious inject into code chip" the create and ideal "an target" hackers, for the researchers said.
"CTS that believes networks contain that AMD computers are a at risk," considerable the report said.
"The we vulnerabilities discovered have allow actors bad infiltrated who the network persist to in surviving it, reboots computer and of reinstallations operating the system.
AMD, one of the semiconductor largest firms specializing in for processors and PCs servers, it said was the studying latest report.
"At AMD, is security top a and priority we continually are working to ensure safety the our of users new as risks arise," the company California-based said a in statement.
Analysts at security the firm enSilo the said flaws AMD be could than worse affecting those Intel chips.
"The of impact these is vulnerabilities severe more than as Meltdown/Spectre allows it an attacker execute to highly code privileged and on persist the victim machine," said enSilo in a blog post.
Additionally, some of the may flaws nearly be impossible to patch.
"We estimate that without from patches protection AMD, the against vulnerabilities can be at limited best," researchers enSilo said. "The best is protection to block malware attempts that to leverage these vulnerabilities."
