Second-Generation Ryzen Processors Up For Pre-Order – Ubergizmo

Ubergizmo Second-Generation Ryzen Processors Up For Pre-Order Ubergizmo AMD's Ryzen processors have been very well received as they offered proper competition to competing products from market leader Intel. The company certainly wants to build up on that foundation which is why it launched the second-generation Ryzen ... and more »

A raft of flaws in AMD chips makes bad hacks much, much worse

Enlarge (credit: AMD ) Secure enclaves like the one found in iPhones are intended to be impenetrable fortresses that handle tasks too sensitive for the main CPUs they work with. AMD's version of that co-processor contains a raft of critical flaws that attackers could exploit to run malware that's nearly impossible to detect and has direct access to a vulnerable computer's most sensitive secrets, a report published Tuesday warned. The chips also contain what the report called "backdoors" that hackers can exploit to gain administrative access. The flaws—in AMD's EPYC, Ryzen, Ryzen Pro, and Ryzen Mobile lines of processors—require attackers to first gain administrative rights on a targeted network or computer, which is a hurdle that's difficult but by no means impossible to clear. From there, attackers can exploit the vulnerabilities to achieve a variety of extraordinary feats that would be catastrophic for the owners' long-term security. Among other things, the feats include: Running persistent malware inside the AMD Secure Processor that's impossible—or nearly impossible—to detect Bypassing advanced protections such as AMD's Secure Encrypted Virtualization , Firmware Trusted Platform Module , and other security features, which are intended to secure systems and sensitive data in the event that malware infects a computer's operating system Stealing credentials a vulnerable computer uses to access networks Physically destroying hardware by attackers in hardware-based "ransomware" scenarios “All these things are real” The four classes of vulnerabilities—dubbed Masterkey, Ryzenfall, Fallout, and Chimera—were described in a 20-page report headlined " Severe Security Advisory on AMD Processors ." The advisory came with its own disclaimer that CTS—the Israeli research organization that published the report—"may have, either directly or indirectly, an economic interest in the performance" of the stock of AMD or other companies. It also discloses that its contents were all statements of opinion and "not statements of fact." Critics have said the disclaimers, which are highly unusual in security reports, are signs that the report is exaggerating the severity of the vulnerabilities in a blatant attempt to effect the stock price of AMD and possibly other companies. Critics also faulted the researchers for giving AMD just 24 hours to review the report before it went public and using a dedicated-website to bring attention to the flaws.

Security researchers find flaws in AMD chips but raise eyebrows with rushed disclosure

 A newly discovered set of vulnerabilities in AMD chips is making waves not because of the scale of the flaws, but rather the rushed, market-ready way they were disclosed by the researchers. When was the last time a bug had its own professionally shot video and PR rep, yet the company was only alerted 24 hours ahead of time? The flaws may be real, but the precedent set here is an unsavory one. Read More
