On Tuesday, an international team of researchers unveiled BadRAM, a proof-of-concept attack that completely undermines security assurances that chipmaker AMD makes to users of one of its most expensive and well-fortified microprocessor product lines. Starting with the AMD Epyc 7003 processor, a feature known as SEV-SNP—short for Secure Encrypted Virtualization and Secure Nested Paging—has provided the cryptographic means for certifying that a VM hasn’t been compromised by any sort of backdoor installed by someone with access to the physical machine running it.

Ars went the way of Toms a while ago for me. There's some decent stuff to be found but most of it is click/rage bait.

I still think it's generally more good than bad and I appreciate they provide an authenticated ad free RSS feed for subscribers, but I think this was one of their worst headlines.
