CPU Side-Channel Information Disclosure Vulnerabilities: May 2018
On May 21, 2018, researchers disclosed two vulnerabilities that take advantage of the implementation of speculative execution of instructions on many modern microprocessor architectures to perform side-channel information disclosure attacks. These vulnerabilities could allow an unprivileged, loca...
Intel the reproduction of new vulnerabilities or be subjected to hackers implant attack script-vulnerability warning-the black bar safety net
5 on 22, reported,yesterday, Intel and Microsoft announced a Spectre and Meltdown security vulnerability, the new variant-the“variant 4”. The new variant is the use of“Speculative Store Bypass”, the defect enables the Processor chip to a potential unsafe area to disclose sensitive information...
CVE-2018-3640: Observable Discrepancy
Systems with microprocessors utilizing speculative execution and that perform speculative reads of system registers may allow unauthorized disclosure of system parameters to an attacker with local user access via a side-channel analysis, aka Rogue System Register Read RSRE, Variant 3a...

Wicked Botnet Uses Passel of Exploits to Target IoT
Yet another variant of the Mirai botnet has appeared on the scene, but this one has a twist: The code is integrated with at least three exploits that target unpatched IoT devices, including closed-circuit cameras and Netgear routers. It also has ties to a web of other botnets, made for DDoS...
CPU hardware utilizing speculative execution may be vulnerable to cache side-channel attacks
Overview CPU hardware utilizing speculative execution may be vulnerable to cache timing side-channel analysis. Two vulnerabilities are identified, known as "Variant 3a" and "Variant 4". Description Speculative execution is a technique used by many modern processors to improve performance by...
