Modern computer systems are facing security challenges and thus are forced to employ various encryption, mitigation mechanisms, and other measures that affect significantly their performance. In this study, we aim to identify the energy and run-time performance implications of Meltdown and Spectre mitigation mechanisms.

Kaspersky Security Bulletin 2018. Top security stories
Securelist • David Emm Victor Chebyshev • 03 Dec 2018

The internet is now woven into the fabric of our lives. Many people routinely bank, shop and socialize online and the internet is the lifeblood of commercial organizations. The dependence on technology of governments, businesses and consumers provides a broad attack surface for attackers with all kinds of motives – financial theft, theft of data, disruption, damage, reputational damage or simply ‘for the lulz’. The result is a threat landscape that ranges from highly sophisticated targeted...

Microsoft, Google: We've found a fourth data-leaking Meltdown-Spectre CPU hole
The Register • Chris Williams, Editor in Chief • 21 May 2018

Design blunder exists in Intel, AMD, Arm, Power processors

A fourth variant of the data-leaking Meltdown-Spectre security flaws in modern processors has been found by Microsoft and Google researchers.
These speculative-execution design blunders can be potentially exploited by malicious software running on a vulnerable device or computer, or a miscreant logged into the system, to slowly extract secrets, such as passwords, from protected kernel or application memory, depending on the circumstances.
Variants 1 and 2 are known as Spectre (CVE-20...

Security researchers from Google and Microsoft have found two new variants of the Spectre attack that affects processors made by AMD, ARM, IBM, and Intel.
Rumors about this new flaw leaked online at the start of the month in a German magazine, but actual details were published today.
AMD, ARM, IBM, Intel, Microsoft, Red Hat and Ubuntu have published security advisories at the time of writing, containing explanations of how the bugs work, along with mitigation advice.

BleepingComputer • Catalin Cimpanu • 29 Mar 2018

Microsoft issued today an out-of-band security update for 64-bit versions of Windows 7 and Windows Server 2008 R2.
The security update —KB4100480— addresses a security bug discovered by a Swedish security expert earlier this week.
The bug was caused by a patch meant to fix the Meltdown vulnerability but accidentally opened the kernel memory wide open.
According to Ulf Frisk, Microsoft's January 2018 Meltdown patch (for CVE-2017-5754) allowed any app to extract or write cont...

Meltdown Patch Opened Bigger Security Hole on Windows 7
BleepingComputer • Catalin Cimpanu • 27 Mar 2018

Microsoft's Meltdown patch has opened an even bigger security hole on Windows 7, allowing any user-level application to read content from the operating system's kernel, and even write data to kernel memory.
Swedish IT security expert Ulf Frisk made the discovery earlier this month while working on PCILeech, a device he created a few years back for carrying out Direct Memory Access (DMA) attacks and dumping protected OS memory.
Frisk says that Microsoft's Meltdown patch (for CVE-2017-...

List of Meltdown and Spectre Vulnerability Advisories, Patches, & Updates
BleepingComputer • Lawrence Abrams • 01 Jan 1970

Two new vulnerabilities called Meltdown and Spectre, or speculative execution side-channel vulnerabilities, have been discovered in modern processors that allow malicious programs to steal information from the memory of other programs. This means that the malicious program can steal passwords, account information, encryption keys, or theoretically anything stored in the memory of a process.
Vendors have started to release information on how customers can protect themselves from Spectre o...
