Foreshadow Attack | Breaking Cybersecurity News | The Hacker News

It turns out that the root cause behind several previously disclosed speculative execution attacks against modern processors, such as Meltdown and Foreshadow , was misattributed to 'prefetching effect,' resulting in hardware vendors releasing incomplete mitigations and countermeasures. Sharing its findings with The Hacker News, a group of academics from the Graz University of Technology and CISPA Helmholtz Center for Information Security finally revealed the exact reason behind why the kernel addresses are cached in the first place, as well as presented several new attacks that exploit the previously unidentified underlying issue, allowing attackers to sniff out sensitive data. The new research explains microarchitectural attacks were actually caused by speculative dereferencing of user-space registers in the kernel, which not just impacts the most recent Intel CPUs with the latest hardware mitigations, but also several modern processors from ARM, IBM, and AMD — previou

2018 has been quite a tough year for Intel. While the chip-maker giant is still dealing with Meltdown and Spectre processor vulnerabilities, yet another major speculative execution flaw has been revealed in Intel's Core and Xeon lines of processors that may leave users vulnerable to cyber-attacks. Dubbed Foreshadow , alternatively called L1 Terminal Fault or L1TF, the new attacks include three new speculative execution side-channel vulnerabilities affecting Intel processors. The Foreshadow attacks could allow a hacker or malicious application to gain access to the sensitive data stored in a computer's memory or third-party clouds, including files, encryption keys, pictures, or passwords. The three Foreshadow vulnerabilities have been categorized into two variants: 1.) Foreshadow Foreshadow ( PDF ) targets a new technology originally been designed to protect select code and users' data from disclosure or modification, even if the entire system falls under a

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.
