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
Researchers have demonstrated an attack that can break through modern Intel and AMD processor technologies that protect encrypted data stored in memory.
Google Expects Tactics to Spread; Global Targets and Other Services at RiskRussian nation-state hackers are using phishing attacks to target Ukrainian users of the chat app Signal, say security researchers. Rather than circumventing Signal's end-to-end encryption via a cryptographic attack, attackers use malicious prompting to prod victims into exposing messages.
Researchers have discovered two novel attack methods targeting high-performance Intel CPUs that could be exploited to stage a key recovery attack against the Advanced Encryption Standard (AES) algorithm
A senior research scientist at Google has devised new CPU attacks to exploit a vulnerability dubbed Downfall that affects multiple Intel microprocessor families and allows stealing passwords, encryption keys, and private data like emails, messages, or banking info from users that share the same computer. [...]
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
NIST's nifty new algorithm looks like it's in trouble One of the four encryption algorithms the US National Institute of Standards and Technology (NIST) recommended as likely to resist decryption by quantum computers has has holes kicked in it by researchers using a single core of an Intel Xeon CPU, released in 2013.…
A newly discovered security vulnerability in modern Intel and AMD processors could let remote attackers steal encryption keys via a power side channel attack
