7 New Meltdown and Spectre-type CPU Flaws Affect Intel, AMD, ARM CPUs

7 New Meltdown and Spectre-type CPU Flaws Affect Intel, AMD, ARM CPUs

November 14, 2018Swati Khandelwal
Disclosed earlier this year, potentially dangerous Meltdown and Spectre vulnerabilities that affected a large family of modern processors proven that speculative execution attacks can be exploited in a trivial way to access highly sensitive information. Since then, several more variants of speculative execution attacks have been discovered, including Spectre-NG , SpectreRSB, Spectre 1.1, Spectre1.2, TLBleed , Lazy FP , NetSpectre and Foreshadow , patches for which were released by affected vendors time-to-time. Speculative execution is a core component of modern processors design that speculatively executes instructions based on assumptions that are considered likely to be true. If the assumptions come out to be valid, the execution continues, otherwise discarded. Now, the same team of cybersecurity researchers who discovered original Meltdown and Spectre vulnerabilities have uncovered 7 new transient execution attacks affecting 3 major processor vendors—Intel, AMD, ARM.

A team of security researchers has reportedly discovered a total of eight new " Spectre-class " vulnerabilities in Intel CPUs, which also affect at least a small number of ARM processors and may impact AMD processor architecture as well. Dubbed Spectre-Next Generation , or Spectre-NG , the partial details of the vulnerabilities were first leaked to journalists at German computer magazine Heise, which claims that Intel has classified four of the new vulnerabilities as "high risk" and remaining four as "medium." The new CPU flaws reportedly originate from the same design issue that caused the original Spectre flaw , but the report claims one of the newly discovered flaws allows attackers with access to a virtual machine (VM) to easily target the host system, making it potentially more threatening than the original Spectre vulnerability. "Alternatively, it could attack the VMs of other customers running on the same server. Passwords and secret k
Apple Plans to Replace Intel Chips in Macs with its Custom Designed CPUs

Apple Plans to Replace Intel Chips in Macs with its Custom Designed CPUs

April 03, 2018Mohit Kumar
In a major blow to Intel, Apple is reportedly planning to use its custom-designed ARM chips in Mac computers starting as early as 2020, ultimately replacing the Intel processors running on its desktop and laptop hardware. The company makes its own A-series custom chips for iPhones, iPads and other iThings, while the Mac devices use Intel x64 silicon. Now according to a report from Bloomberg, Apple plans to replace Intel's Mac chips with its own homegrown CPUs. The report says Apple executives have a project, codenamed " Kalamata ," that designs desktop-grade Arm-compatible processors, along with a macOS port, allowing the company to craft a uniform architecture across all of its product lines. The report also says this changeover would be part of a "multi-step transition" to make iOS devices and Macs "work more similarly and seamlessly together," helping Apple's plan (project codename ' Marzipan ') to bring iOS apps to Mac for sof

Meltdown and Spectre CPU Flaws Affect Intel, ARM, AMD Processors

Unlike the initial reports suggested about Intel chips being vulnerable to some severe 'memory leaking' flaws, full technical details about the vulnerabilities have now been emerged, which revealed that almost every modern processor since 1995 is vulnerable to the issues. Disclosed today by Google Project Zero , the vulnerabilities potentially impact all major CPUs, including those from AMD, ARM, and Intel—threatening almost all PCs, laptops, tablets, and smartphones, regardless of manufacturer or operating system. These hardware vulnerabilities have been categorized into two attacks , named Meltdown (CVE-2017-5754) and Spectre (CVE-2017-5753 and CVE-2017-5715), which could allow attackers to steal sensitive data which is currently processed on the computer. Both attacks take advantage of a feature in chips known as "speculative execution," a technique used by most modern CPUs to optimize performance. "In order to improve performance, many CPUs may choose t
Microsoft Started Blocking Windows 7/8.1 Updates For PCs Running New Processors

Microsoft Started Blocking Windows 7/8.1 Updates For PCs Running New Processors

March 20, 2017Wang Wei
You might have heard the latest news about Microsoft blocking new security patches and updates for Windows 7 and Windows 8.1 users running the latest processors from Intel, AMD, Qualcomm, and others. Don't panic, this new policy doesn't mean that all Windows 7 and 8.1 users will not be able to receive latest updates in general because Microsoft has promised to support Windows 7 until 2020 , and Windows 8.1 until 2023. But those who have upgraded their machines running older versions of Windows to the latest processors, or manually downgraded their new laptops to run Windows 7/8.1 would be out of luck. A recently published Microsoft Knowledge Base article suggests that if you are running the older version of operating systems on your computers that feature new processors, including Intel's 7th generation Core i3, i5 and i7 ("Kaby Lake"), AMD Ryzen ("Bristol Ridge") and Qualcomm 8996 chips or later, the security updates will not install.

Japan's Softbank buys semiconductor giant ARM for $32 Billion in Cash

Japan's Softbank buys semiconductor giant ARM for $32 Billion in Cash

July 18, 2016Swati Khandelwal
Japanese telecommunication giant SoftBank has confirmed that the company intends to acquire UK chip designer ARM Holdings for almost $32 Billion (£24.3 Billion) in an all-cash deal. ARM has also agreed to this offer from SoftBank and said that its board would recommend the all-cash deal to shareholders. SoftBank will pay nearly $22.5 per ARM share, which is 43 percent more than ARM's closing share price on Friday and 41 percent more than ARM's all-time high closing share price. The deal is the largest-ever acquisition of a European technology business, first reported by The Financial Times. Wondering Why is ARM really Worth $32 Billion? Founded in 1990, Cambridge-based ARM Holdings designs microchips for a variety of smartphones and powers more than 95 percent of the smartphones in the market. Whether it is Apple's iPhones or iPads, Samsung's Galaxy smartphones, Amazon's Kindle e-readers, the cheapest Nokia phones or Internet-connected devices li

Raspberry Pi 3 to get official Android OS support

May 26, 2016Swati Khandelwal
It's fair to say the success of the ARM-powered Raspberry Pi computers have surpassed expectations and have been a godsend to hobbyists, hackers, and students. If you're one of those people looking for unofficial hacks to install Android OS on a Raspberry Pi device, then stop and wait for the official release. Raspberry Pi computers have largely been Linux affairs, as several Linux distributions have supported this tiny ARM computer. Now, it seems like Raspberry Pi is ready to get official support for one of the most popular mobile operating systems out there: Android . Google has recently registered the $35 Raspberry Pi 3 ‒ the newest version of the Raspberry Pi ‒ as a new device 'tree' in its Android Open Source Project (AOSP) repository . If you're not aware, Raspberry Pi is cheap, credit card-sized, single board ARM computer that looks and feels very basic, but could be built into many geeky projects. What Google is planning for Android and the P

Great news for Hackers and Backtrack Linux fans! The most awaited penetration testing Linux distribution has been released called ' Kali Linux ' or ' Backrack 6 ', from the creators of BackTrack itself. From last 7 years we have seen five awesome versions of Backtrack Linux. But this time to achieve some higher goals, team decided to leave the 4 years old development architecture and ' Kali Linux ' born today. Kali Linux is based upon Debian Linux, instead of Ubuntu and new streamlined repositories synchronize with the Debian repositories 4 times a day, constantly providing users with the latest package updates and security fixes available. Another great feature introduced is that, because of Debian compliant system, it is now able to Bootstrap a Kali Installation/ISO directly from Kali repositories. This allow any user to easily build their own customization of Kali, as well as perform enterprise network installs from a local or remote repository. The Kali Li

Running Desktop Apps on Windows RT, The Hackers Way!

January 08, 2013Wang Wei
A hacker claims to have found a method in the code integrity mechanism in Windows RT, that allow one to bypass security mechanism preventing unauthorized software running on ARM-powered Windows RT tablets. Lets see, How to Run traditional desktop apps on Windows RT in a Hackers  Way! A hacker called ' C. L. Rokr ' explain about the Windows RT exploit on his blog , which requires manipulating a part of Windows RT's system memory that governs whether unsigned apps can run. Windows RT is a special version of Microsoft Windows designed for lightweight PCs and tablets that are based on the ARM architecture, including Microsoft's Surface tablet.  Clrokr said Windows RT inherited a flaw from Windows 8 that makes the workaround possible. " Ironically, a vulnerability in the Windows kernel that has existed for some time and got ported to ARM just like the rest of Windows made this possible, ". Specifically, one needs to inject a blob of ARM code into a safe
