Over the weekend, AMD said it planned to do just that in a firmware update scheduled for release next month. More often than not, the chipmaker refers to TSME as Memory Guard. “Regarding certain non-PRO Ryzen 9000-series desktop processors, a BIOS option to enable Memory Guard was previously available but was removed in a recent… Read More: Following user outcry, AMD reinstates memory encryption in consumer CPUs »
Limoncello promptly replied: “My apologies; but I don’t have any more information to share on this topic.” With that, the discussion and Kilpatrick’s inquiry were over. The Lendacky comment in 2020 Kilpatrick referred to came in this thread discussing encryption features available in AMD CPUs. Lendacky said that the Ryzen 3700x, a consumer CPU, “should… Read More: Users cry foul after AMD stripped memory crypto from its… »

Cheap, quick, and the size of a briefcase “Now that we have interpositioned DDR5 traffic, our work shows that even the most modern of TEEs across all vendors with available hardware is vulnerable to cheap physical attacks,” Genkin said. The equipment required by TEE.fail runs off-the-shelf gear that costs less than $1,000. One of the… Read More: New physical attacks are quickly diluting secure enclave defenses from… »
As part of the arrangement, AMD will allow OpenAI to purchase up to 160 million AMD shares at 1 cent each throughout the chips deal. OpenAI diversifies its chip supply With demand for AI compute growing rapidly, companies like OpenAI have been looking for secondary supply lines and sources of additional computing capacity, and the… Read More: AMD wins massive AI chip deal from OpenAI with stock… »
The key benefit of Battering RAM is that it requires equipment that costs less than $50 to pull off. It also allows active decryption, meaning encrypted data can be both read and tampered with. In addition, it works against both SGX and SEV-SNP, as long as they work with DDR4 memory modules. Wiretap Wiretap, meanwhile,… Read More: Intel and AMD trusted enclaves, the backbone of network security,… »
Chinese firms have begun rushing to order Nvidia’s H20 AI chips as the company plans to resume sales to mainland China, Reuters reports.

If a VM has been backdoored, the cryptographic attestation will fail and immediately alert the VM admin of the compromise. Or at least that’s how SEV-SNP is designed to work. BadRAM is an attack that a server admin can carry out in minutes, using either about $10 of hardware, or in some cases, software only,… Read More: AMD’s trusted execution environment blown wide open by new BadRAM… »
On Thursday, AMD announced its new MI325X AI accelerator chip, which is set to roll out to data center customers in the fourth quarter of this year. At an event hosted in San Francisco, the company claimed the new chip offers “industry-leading” performance compared to Nvidia’s current H200 GPUs, which are widely used in data… Read More: AMD unveils powerful new AI chip to challenge Nvidia »
