Intel SGX Enclaves | Breaking Cybersecurity News | The Hacker News

A team of cybersecurity researchers demonstrated a novel yet another technique to hijack Intel SGX, a hardware-isolated trusted space on modern Intel CPUs that encrypts extremely sensitive data to shield it from attackers even when a system gets compromised. Dubbed Plundervolt and tracked as CVE-2019-11157, the attack relies on the fact that modern processors allow frequency and voltage to be adjusted when needed, which, according to researchers, can be modified in a controlled way to induce errors in the memory by flipping bits. Bit flip is a phenomenon widely known for the Rowhammer attack wherein attackers hijack vulnerable memory cells by changing their value from 1 to a 0, or vice versa—all by tweaking the electrical charge of neighboring memory cells. However, since the Software Guard Extensions (SGX) enclave memory is encrypted, the Plundervolt attack leverages the same idea of flipping bits by injecting faults in the CPU before they are written to the memory. Plundervo

Cybersecurity researchers have discovered a way to hide malicious code in Intel SGX enclaves, a hardware-based memory encryption feature in modern processors that isolates sensitive code and data to protect it from disclosure or modification. In other words, the technique allows attackers to implant malware code in a secure memory that uses protection features of SGX which are otherwise designed to protect important data from prying eyes or from being tampered, even on a compromised system. Introduced with Intel's Skylake processors, SGX (Software Guard Extensions) allows developers to run selected application modules in a completely isolated secure region of memory, called enclaves, which are designed to be protected from processes running at higher privilege levels like the operating system, kernel, BIOS, SMM, hypervisor, etc. However, a team of researchers, some of whom were behind the discovery of the Spectre-Meltdown CPU flaws , managed to bypass this protection and g

As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.
