9 Years of AMD Processors Vulnerable to 2 New Side-Channel Attacks

9 Years of AMD Processors Vulnerable to 2 New Side-Channel Attacks

Mar 09, 2020
AMD processors from as early as 2011 to 2019 carry previously undisclosed vulnerabilities that open them to two new different side-channel attacks, according to a freshly published research. Known as " Take A Way ," the new potential attack vectors leverage the L1 data (L1D) cache way predictor in AMD's Bulldozer microarchitecture to leak sensitive data from the processors and compromise the security by recovering the secret key used during encryption. The research was published by a group of academics from the Graz University of Technology and Research Institute of Computer Science and Random Systems (IRISA), who responsibly disclosed the vulnerabilities to AMD back in August 2019. "We are aware of a new white paper that claims potential security exploits in AMD CPUs, whereby a malicious actor could manipulate a cache-related feature to potentially transmit user data in an unintended way," AMD said in an advisory posted on its website over the weekend...
New 'Lazy FP State Restore' Vulnerability Found in All Modern Intel CPUs

New 'Lazy FP State Restore' Vulnerability Found in All Modern Intel CPUs

Jun 14, 2018
Hell Yeah! Another security vulnerability has been discovered in Intel chips that affects the processor's speculative execution technology—like Specter and Meltdown —and could potentially be exploited to access sensitive information, including encryption related data. Dubbed Lazy FP State Restore , the vulnerability (CVE-2018-3665) within Intel Core and Xeon processors has just been confirmed by Intel, and vendors are now rushing to roll out security updates in order to fix the flaw and keep their customers protected. The company has not yet released technical details about the vulnerability, but since the vulnerability resides in the CPU, the flaw affects all devices running Intel Core-based microprocessors regardless of the installed operating systems, except some modern versions of Windows and Linux distributions. As the name suggests, the flaw leverages a system performance optimization feature, called Lazy FP state restore, embedded in modern processors, which is resp...
Entra ID Data Protection: Essential or Overkill?

Entra ID Data Protection: Essential or Overkill?

May 06, 2025SaaS Security / Identity Management
Microsoft Entra ID (formerly Azure Active Directory) is the backbone of modern identity management, enabling secure access to the applications, data, and services your business relies on. As hybrid work and cloud adoption accelerate, Entra ID plays an even more central role — managing authentication, enforcing policy, and connecting users across distributed environments. That prominence also makes it a prime target. Microsoft reports over 600 million attacks on Entra ID every day. These aren't just random attempts, but include coordinated, persistent, and increasingly automated campaigns designed to exploit even small vulnerabilities. Which brings us to the core question: Are Entra ID's native protections enough? Where do they fall short — and what steps should you take to close the gaps and ensure you're covered? Understanding Entra ID At its core, Microsoft Entra ID is your enterprise identity and access management system. It defines how users prove who they are, what resources...
This Open Source 25-Core Processor Chip Can Be Scaled Up to 200,000-Core Computer

This Open Source 25-Core Processor Chip Can Be Scaled Up to 200,000-Core Computer

Aug 26, 2016
Researchers have designed a new computer chip that promises to boost the performance of computers and data centers while processing applications in parallel. Princeton University researchers have developed a 25-core open source processor, dubbed Piton named after the metal spikes used by rock climbers, which has been designed to be flexible, highly scalable, fast and energy-efficient to satisfy the demands of massive-scale data centers. Every computer has a processor, but it's the core, a processing unit, which defines its actual efficiency and performance. A Processor can have a single core or multiple cores, which receive instructions, then performs calculations on it based on those instructions, and gives the results back. For example, the four independent processing units i.e. Cores of a quad-core processor can run multiple instructions at the same time, increasing the overall performance for applications compatible with parallel processing.
