Researchers built an inexpensive device that circumvents chipmakers' confidential computing protections and reveals weaknesses in scalable memory encryption.
Cyberattacks are getting smarter and harder to stop. This week, hackers used sneaky tools, tricked trusted systems, and quickly took advantage of new security problems—some just hours after being found. No system was fully safe
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.
Tulsi Gabbard Takes Credit After Apparent British Reversal of Backdoor RequestU.S. Director of National Intelligence Tulsi Gabbard announced the United Kingdom has apparently reversed course on a demand for Apple to provide the government with a backdoor into its advanced iCloud encrypted protections following growing criticism from U.S. lawmakers and privacy advocates.
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
AMD Zen chips, meanwhile, are vulnerable to side-channel data scrying A group of computer scientists has identified an architectural error in certain recent Intel CPUs that can be abused to expose SGX enclave data like private encryption keys.…
A late-stage candidate encryption algorithm that was meant to withstand decryption by powerful quantum computers in the future has been trivially cracked by using a computer running Intel Xeon CPU in an hour's time
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
