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

Hands-on Review: Cynomi AI-powered vCISO Platform

Apr 10, 2024vCISO / Risk Assessment
The need for vCISO services is growing. SMBs and SMEs are dealing with more third-party risks, tightening regulatory demands and stringent cyber insurance requirements than ever before. However, they often lack the resources and expertise to hire an in-house security executive team. By outsourcing security and compliance leadership to a vCISO, these organizations can more easily obtain cybersecurity expertise specialized for their industry and strengthen their cybersecurity posture. MSPs and MSSPs looking to meet this growing vCISO demand are often faced with the same challenge. The demand for cybersecurity talent far exceeds the supply. This has led to a competitive market where the costs of hiring and retaining skilled professionals can be prohibitive for MSSPs/MSPs as well. The need to maintain expertise of both security and compliance further exacerbates this challenge. Cynomi, the first AI-driven vCISO platform , can help.

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.
