    As a performance junkie, I’m less concerned about the security risks of the Spectre and Meltdown vulnerabilities—after all, there are no known exploits in use today—than I am about a performance hit from the fixes.And from what I’m seeing, my concerns are warranted.My sole experience with a fully updated platform so far is with Microsoft’s original Surface Book. It’s based on an Intel “Skylake” Core i7-6700U and has 16GB of LPDDR3 and a 512GB Samsung 950 Pro NVMe drive. The Surface Book is running the 64-bit Windows 10 Pro Fall Creator’s Update.[ Further reading: How to remove malware from your...

    security week ^ | 1/8/2018 | Eduard Kovacs
    Users have complained that the updates released by Microsoft last week for the Spectre and Meltdown vulnerabilities cause Windows to break down on some computers with AMD processors. Several individuals whose computers rely on AMD processors, particularly older Athlon models, say they are unable to start Windows 10 after installing KB4056892, an update released by Microsoft in response to the disclosure of serious flaws affecting Intel, AMD and ARM processors. The security holes have been dubbed Spectre and Meltdown and they allow malicious applications to bypass memory isolation mechanisms and access passwords, photos, documents, emails, and other sensitive information. Both...

    A series of flaws have been discovered in Intel, AMD, and ARM chipsets that allow speculative references to be probed for privileged data. "Meltdown" is a flaw currently believed to affect only Intel processors and "melts security boundaries which are normally enforced by the hardware". "Spectre" is a flaw that affects Intel, AMD, and ARM processors due to the way "speculative execution" is handled. Both could theoretically be used to read information from a computer's memory, including private information like passwords, photos, messages, and more. Apple has apparently already started patching Meltdown in macOS. Here's what you need to know....

    What are Meltdown and Spectre? Do they only affect Intel chips? Will the fixes slow my computer … and what even is a processor? Meltdown and Spectre are the names of two serious security flaws that have been found within computer processors. They could allow hackers to steal sensitive data without users knowing, one of them affecting chips made as far back as 1995. What are Meltdown and Spectre? Meltdown is a security flaw that could allow hackers to bypass the hardware barrier between applications run by users and the computer’s core memory, which is normally highly protected. Spectre is...

    Two major flaws in computer chips could leave a huge number of computers and smartphones vulnerable to security concerns, researchers revealed Wednesday. And a U.S. government-backed body warned that the chips themselves need to be replaced to completely fix the problems. The flaws could allow an attacker to read sensitive data stored in the memory, like passwords, or look at what tabs someone has open on their computer, researchers found. Daniel Gruss, a researcher from Graz University of Technology who helped identify the flaw, said it may be difficult to execute an attack, but billions of devices were impacted. Related:...

    Apple’s iPhones, iPads and Mac computers are all vulnerable to the major processor flaws revealed on Wednesday, the company has warned, but it says updates are already available. The flaws known as Meltdown and Spectre affect almost every modern computing device from all manufacturers using chip designs from Intel, AMD and ARM. Apple uses Intel processors in its Mac computers and ARM-based designs for its A-series processors used in the iPhone, iPad, Apple TV and Apple Watch lines. Apple said: “All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at this time.” The...

    Like the Meltdown bug, the Spectre bug is a hardware bug in the form of a CPU design flaw. Unlike the Meltdown bug which only affects Intel processors, the Spectre bug impacts Intel, AMD, and some ARM (used in many smart phones and other mobile devices) processors. These three are by far the most common CPUs on the planet, running literally billions of devices. In a Spectre attack, the CPU is tricked into executing instructions that it normally would not, causing leaks in the victims memory address space.

    Microsoft has warned some PC users they will not be able to apply an emergency Windows patch because their security software is incompatible. The out-of-bounds update was issued by Microsoft yesterday to address the Meltdown and Spectre flaws in Intel chips. These vulnerabilities affect most PCs and servers, and can be exploited to allow an attacker to read sensitive information, such as passwords, from protected memory. The Spectre flaw also affects AMD chips, but is considerably more difficult to exploit, as well as a small number of Arm-based processors. However, not every Microsoft system will be able to apply the...

    What is the Meltdown bug? Most of the bugs that make the news are software bugs, but the Meltdown bug is a hardware bug (in the form of a design flaw) that affects Intel processors going back several generations. In a nut shell, the Meltdown bug is a brand new way to (possibly) steal your information.

    Only Intel machines are affected by Meltdown Details have emerged on two major processor security flaws this week, and the industry is scrambling to issue fixes and secure machines for customers. Dubbed “Meltdown” and “Spectre,” the flaws affect nearly every device made in the past 20 years. The Meltdown flaw only affects Intel processors, and researchers have already released proof of concept code that could lead to attacks using Meltdown. The vulnerabilities allow an attacker to compromise the privileged memory of a processor by exploiting the way processes run in parallel. They also allow an attacker to use JavaScript code...

    Here’s what you need to know about Meltdown and Spectre, the two huge bugs that affect practically every computer and device out there. What are these flaws? Short answer: Bugs at a fundamental level that allow critical information stored deep inside computer systems to be exposed. Security researchers released official documentation — complete with nicknames and logos —  of two major flaws found in nearly all modern central processing units, or CPUs. It’s not a physical problem with the CPUs themselves, or a plain software bug you might find in an application like Word or Chrome. It’s in between, at...

    As many of you know as I started my Christmas holiday last night and employed a new app called PostBot to fulfill my commitment and obligations as a productive and engaged member of FR while taking much needed time off. After running it for approximately 24 hours I can report the following. 1. The app kept track of what it perceived were negative replies to those it determined were positive. The ratio was approximately 20:1 positive. 2. It compiled lists from the negative responses as to belligerent (9), thin-skinned (18), irrational (6), nasty (11) and self-righteous/sanctimonious (22). A total of...

    On Nov. 8, 2016, I was on the hook to file several election-related pieces, and had made the process easier for myself by pre-writing four different versions of “What does the first female president mean for America?” It was 3 a.m. when I woke up in Nairobi, Kenya, where I was living that year, and as I opened the New York Times app and saw an electoral map that looked awfully red, I thought that I might still be dreaming. Not that it really mattered — states that are physically large often go Republican, so a red South and middle...

So, that’s number one.” He continued, “No Senate candidate across the country wants to be associated with Mitch McConnell. Then you have to ask the question, why do these candidates not want to be publicly associated with Mitch...

    October 16, 2017 12:45 pm NBC has tracked down and fired the employee responsible for leaking the video of MSNBC host Lawrence O'Donnell's infamous meltdown, during which he cursed at his crew and yelled about hearing random noises in his earpiece during a live broadcast of his show. Multiple sources said a male editor for the "Today" show compiled and leaked the eight-minute video to Mediaite last month of O'Donnell yelling at his staff during the Aug. 29 broadcast of his show, "The Last Word," according to Page Six. In the clip, an increasingly perturbed O’Donnell slams his fist on...
