Windows 10 'S Mode' Coming Soon — For Security and Performance

Windows 10 'S Mode' Coming Soon — For Security and Performance

March 09, 2018Mohit Kumar
Microsoft has confirmed that the company is planning to convert Windows 10 S from a dedicated operating system to a special " S Mode " that will be available in all versions of Windows. Windows 10 S, a new operating system designed for simplicity, security, and speed, was released by Microsoft last year. It locks a computer down to run applications only downloaded from official Windows Store, but the slimmed-down and restricted flavor of Windows did not exactly turn out to be a success. Therefore, the company has now decided Windows 10 S be offered as an optional mode rather than a dedicated operating system. Windows 10 S was developed to simplify administration for school or business sysadmins that want the 'low-hassle' guaranteed performance version. It has been designed to deliver predictable performance and quality through Microsoft-verified apps via the Microsoft Store. However, in a blog post published Wednesday, the corporate VP of Microsoft's

October 11, 2017Swati Khandelwal
As part of its "October Patch Tuesday," Microsoft has today released a large batch of security updates to patch a total of 62 vulnerabilities in its products, including a severe MS office zero-day flaw that has been exploited in the wild. Security updates also include patches for Microsoft Windows operating systems, Internet Explorer, Microsoft Edge, Skype, Microsoft Lync and Microsoft SharePoint Server. Besides the MS Office vulnerability, the company has also addressed two other publicly disclosed (but not yet targeted in the wild) vulnerabilities that affect the SharePoint Server and the Windows Subsystem for Linux. October patch Tuesday also fixes a critical Windows DNS vulnerability that could be exploited by a malicious DNS server to execute arbitrary code on the targeted system. Below you can find a brief technical explanation of all above mentioned critical and important vulnerabilities. Microsoft Office Memory Corruption Vulnerability (CVE-2017-11826) T

Windows 10 to Give More Control Over App-level Permissions

September 14, 2017Unknown
Microsoft has been gradually changing its privacy settings in Windows 10 with the Fall Creators Update to give its users more controls over their data. In April, Microsoft addressed some initial privacy concerns in the Windows 10 Creators Update with simplified data collection levels—Security, Basic, Enhanced, and Full—and eventually revealed its data collection practices . Now, the software giant is making another privacy-related change with the upcoming Windows 10 Fall Creators Update, which is due for release in October 2017, giving you much more control over what apps can do with your device. Just like apps on your smartphone's app store, apps on Windows Store also require permission to access your computer's critical functionalities like camera, microphone, calendar, contacts, and music, pictures and video libraries. While Android and iOS allow you to limit an app's permissions to access these sensitive things, these permissions have currently been provided
New GhostHook Attack Bypasses Windows 10 PatchGuard Protections

New GhostHook Attack Bypasses Windows 10 PatchGuard Protections

June 23, 2017Swati Khandelwal
Vulnerabilities discovered in Microsoft PatchGuard kernel protection could allow hackers to plant rootkits on computers running the company's latest and secure operating system, Windows 10. Researchers at CyberArk Labs have developed a new attack technique which could allow hackers to completely bypass PatchGuard, and hook a malicious kernel code (rootkits) at the kernel level. PatchGuard, or (or Kernel Patch Protection) is a software tool that has been designed to forbid the kernel of 64-bit versions of Windows OS from being patched, preventing hackers from running rootkits or executing malicious code at the kernel level. Dubbed GhostHook , the attack is what the CyberArk Labs researchers call the first attack technique that thwarts the defensive technology to bypass PatchGuard, though it requires a hacker to already be present on a compromised system and running code in the kernel. So, basically, this is a post-exploitation attack. "[GhostHook] is neither an

Microsoft Patches Windows Zero-Day Flaw Disclosed by Google

Microsoft was very upset with Google last week when its Threat Analysis Group publically disclosed a critical Windows kernel vulnerability (CVE-2016-7255) that had yet to be patched. The company criticized Google's move , claiming that the disclosure of the vulnerability, which was being exploited in the wild, put its customers "at potential risk." The vulnerability affects all Windows versions from Windows Vista through current versions of Windows 10, and Microsoft was set to issue a fix come this month's Patch Tuesday. So, as part of its monthly Patch Tuesday, Microsoft today patched the security flaw in Windows that was actively being exploited by hackers. According to Microsoft's security bulletin released today, any hacker who tricked victims into running a "specially-crafted application" could successfully exploit the system bug and gain the ability to "install programs; view, change, or delete data; or create new accounts with fu

Microsoft Patches 5 Zero-Day Vulnerabilities Being Exploited in the Wild

Microsoft has released its monthly Patch Tuesday update including a total of 10 security bulletin, and you are required to apply the whole package of patches altogether, whether you like it or not. That's because the company is kicking off a controversial new all-or-nothing patch model this month by packaging all security updates into a single payload, removing your ability to pick and choose which individual patches to install. October's patch bundle includes fixes for at least 5 separate dangerous zero-day vulnerabilities in Internet Explorer, Edge, Windows and Office products that attackers were already exploiting in the wild before the patch release. The patches for these zero-day flaws are included in MS16-118, MS16-119, MS16-120, MS16-121 and MS16-126. All the zero-days are being exploited in the wild, allowing attackers to execute a remote command on victim's system. Although none of the zero-day flaws were publicly disclosed prior to Tuesday, the company wa
