Researchers built an inexpensive device that circumvents chipmakers' confidential computing protections and reveals weaknesses in scalable memory encryption.
A group of academic researchers from Georgia Tech, Purdue University, and Synkhronix have developed a side-channel attack called TEE.Fail that allows for the extraction of secrets from the trusted execution environment (TEE) in a computer's main processor, including Intel's Software Guard eXtensions (SGX) and Trust Domain Extensions (TDX) and AMD's Secure Encrypted Virtualization with Secure
Chipmaker AMD has released fixes to address a security flaw dubbed RMPocalypse that could be exploited to undermine confidential computing guarantees provided by Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP)
Researchers have demonstrated an attack that can break through modern Intel and AMD processor technologies that protect encrypted data stored in memory.
Boffins devise BadRAM attack to pilfer secrets from SEV-SNP encrypted memory Researchers have found that the security mechanism AMD uses to protect virtual machine memory can be bypassed with $10 of hardware – and perhaps not even that.…
A group of academics has disclosed a new "software fault attack" on AMD's Secure Encrypted Virtualization (SEV) technology that could be potentially exploited by threat actors to infiltrate encrypted virtual machines (VMs) and even perform privilege escalation
A group of researchers has revealed details of a new vulnerability affecting Intel CPUs that enables attackers to obtain encryption keys and other secret information from the processors
A newly discovered security vulnerability in modern Intel and AMD processors could let remote attackers steal encryption keys via a power side channel attack
