Microsoft Introduces Linux-Like 'sudo' Command to Windows 11

Microsoft Introduces Linux-Like 'sudo' Command to Windows 11

Feb 12, 2024 Operating System / Technology
Microsoft said it's introducing Sudo for Windows 11 as part of an early preview version to help users execute commands with administrator privileges. "Sudo for Windows is a new way for users to run elevated commands directly from an unelevated console session," Microsoft Product Manager Jordi Adoumie  said . "It is an ergonomic and familiar solution for users who want to elevate a command without having to first open a new elevated console." Sudo, short for superuser do, is a  program  for  Unix-like computer operating systems  that allows users to run programs with the security privileges of another user, usually a user with elevated permissions (e.g., administrator). The feature is available for Windows 11 builds 26045 and later. It can be enabled by heading to Settings > System > For Developers, and setting "Enable sudo" to On. Sudo for Windows comes with three options: run applications in a new elevated console window, run the elevated

Malicious PyPI Packages Slip WhiteSnake InfoStealer Malware onto Windows Machines

Jan 29, 2024 PyPI Repository / Malware
Cybersecurity researchers have identified malicious packages on the open-source Python Package Index (PyPI) repository that deliver an information stealing malware called WhiteSnake Stealer on Windows systems. The malware-laced packages are named nigpal, figflix, telerer, seGMM, fbdebug, sGMM, myGens, NewGends, and TestLibs111. They have been uploaded by a threat actor named "WS." "These packages incorporate Base64-encoded source code of PE or other Python scripts within their setup.py files," Fortinet FortiGuard Labs  said  in an analysis published last week. "Depending on the victim devices' operating system, the final malicious payload is dropped and executed when these Python packages are installed." While Windows systems are infected with WhiteSnake Stealer, compromised Linux hosts are served a Python script designed to harvest information. The activity, which predominantly targets Windows users, overlaps with a  prior campaign  that JFrog
Midnight Blizzard and Cloudflare-Atlassian Cybersecurity Incidents: What to Know

Midnight Blizzard and Cloudflare-Atlassian Cybersecurity Incidents: What to Know

Feb 13, 2024SaaS Security / Data Breach
The Midnight Blizzard and Cloudflare-Atlassian cybersecurity incidents raised alarms about the vulnerabilities inherent in major SaaS platforms. These incidents illustrate the stakes involved in SaaS breaches — safeguarding the integrity of SaaS apps and their sensitive data is critical but is not easy. Common threat vectors such as sophisticated spear-phishing, misconfigurations and vulnerabilities in third-party app integrations demonstrate the complex security challenges facing IT systems. In the case of Midnight Blizzard, password spraying against a test environment was the initial attack vector. For Cloudflare-Atlassian, threat actors initiated the attack via compromised  OAuth tokens  from a prior breach at Okta, a SaaS identity security provider.  What Exactly Happened? Microsoft Midnight Blizzard Breach Microsoft was targeted by the Russian "Midnight Blizzard" hackers (also known as Nobelium, APT29, or Cozy Bear) who are linked to the SVR, the Kremlin's forei
New Variant of DLL Search Order Hijacking Bypasses Windows 10 and 11 Protections

New Variant of DLL Search Order Hijacking Bypasses Windows 10 and 11 Protections

Jan 01, 2024 Windows Security / Vulnerability
Security researchers have detailed a new variant of a dynamic link library ( DLL ) search order hijacking technique that could be used by threat actors to bypass security mechanisms and achieve execution of malicious code on systems running Microsoft Windows 10 and Windows 11. The approach "leverages executables commonly found in the trusted WinSxS folder and exploits them via the classic DLL search order hijacking technique," cybersecurity firm Security Joes  said  in a new report exclusively shared with The Hacker News. In doing so, it allows adversaries to eliminate the need for elevated privileges when attempting to run nefarious code on a compromised machine as well as introduce potentially vulnerable binaries into the attack chain, as  observed   in the   past . DLL search order hijacking , as the name implies, involves  gaming the search order  used to load DLLs in order to execute malicious payloads for purposes of defense evasion, persistence, and privilege escal

Google Using Clang Sanitizers to Protect Android Against Cellular Baseband Vulnerabilities

Google Using Clang Sanitizers to Protect Android Against Cellular Baseband Vulnerabilities

Dec 13, 2023 Mobile Communication / Firmware security
Google is highlighting the role played by  Clang sanitizers  in hardening the security of the cellular baseband in the  Android operating system  and preventing specific kinds of vulnerabilities. This comprises Integer Overflow Sanitizer (IntSan) and BoundsSanitizer (BoundSan), both of which are part of UndefinedBehaviorSanitizer ( UBSan ), a tool designed to catch various kinds of undefined behavior during program execution. "They are architecture agnostic, suitable for bare-metal deployment, and should be enabled in existing C/C++ code bases to mitigate unknown vulnerabilities," Ivan Lozano and Roger Piqueras Jover  said  in a Tuesday post. The development comes months after the tech giant said it's  working with ecosystem partners  to increase the  security of firmware  that interacts with Android, thereby making it difficult for threat actors to achieve remote code execution within the Wi-Fi SoC or the cellular baseband. IntSan and BoundSan are two of the  compi
What is the Essential Eight (And Why Non-Aussies Should Care)

What is the Essential Eight (And Why Non-Aussies Should Care)

Jun 14, 2022
In 2017, The Australian Cyber Security Center (ACSC) published a set of mitigation strategies that were designed to help organizations to protect themselves against cyber security incidents. These strategies, which became known as  the Essential Eight , are designed specifically for use on Windows networks, although variations of these strategies are commonly applied to other platforms. What is the Essential Eight?  The Essential Eight is essentially a cyber security framework that is made up of objectives and controls (with each objective including multiple controls). Initially, the Australian government only mandated that companies adhere to four of the security controls that were included in the first objective. Starting in June of 2022 however, all 98 non-corporate Commonwealth entities (NCCEs) are going to be  required to comply with the entire framework . Non-Australians take note  Although the Essential Eight is specific to Australia, organizations outside of Australia shou
Microsoft Discovers New Privilege Escalation Flaws in Linux Operating System

Microsoft Discovers New Privilege Escalation Flaws in Linux Operating System

Apr 27, 2022
Microsoft on Tuesday disclosed a set of two privilege escalation vulnerabilities in the Linux operating system that could potentially allow threat actors to carry out an array of nefarious activities. Collectively called " Nimbuspwn ," the flaws "can be chained together to gain root privileges on Linux systems, allowing attackers to deploy payloads, like a root backdoor, and perform other malicious actions via arbitrary root code execution," Jonathan Bar Or of the Microsoft 365 Defender Research Team  said  in a report. On top of that, the defects — tracked as  CVE-2022-29799 and CVE-2022-29800  — could also be weaponized as a vector for root access to deploy more sophisticated threats such as ransomware. The vulnerabilities are rooted in a  systemd  component called  networkd-dispatcher , a  daemon program  for the network manager system service that's designed to dispatch network status changes. Specifically, they relate to a combination of  directory t
Apple May Start Delivering Security Patches Separately From Other OS Updates

Apple May Start Delivering Security Patches Separately From Other OS Updates

Mar 17, 2021
Apple may be changing the way it delivers security patches to its devices running iOS and iPadOS mobile operating systems. According to code spotted in iOS 14.5, the iPhone maker is reportedly working on a method for delivering security fixes independently of other OS updates. The changes were first reported by  the 9to5Mac  website. While Google's Android has had monthly security patches rolled out that are completely divorced from the OS-related updates, iOS has traditionally bundled security updates along with an upgrade to the latest version of the OS. For instance, Apple rolled out iOS 14.4.1 earlier this month just to address one security vulnerability in WebKit that could have allowed adversaries to run arbitrary code on devices via malicious web content. But with this new setting called "Install Security Updates" added to the software update menu, it's expected that Apple will let users choose between either installing the entire iOS update or just the
Are You Ready for Microsoft Windows 7 End of Support on 14th January 2020?

Are You Ready for Microsoft Windows 7 End of Support on 14th January 2020?

Jan 07, 2020
January 14, 2020, is a day cybersecurity stakeholders should pay attention to, as it marks the end of Microsoft support in Windows 7. From a security perspective, both the routine monthly security patches as well as hotfixes for attacks in the wild will not be available, effectively making any newly discovered vulnerability a Windows 7 zero-day. Cynet 360 autonomous breach protection is a good example of a multilayered advanced protection solution that can enable organizations who run Windows 7 to remain secure despite the end of support ( to learn more click here ). Let's dig a bit deeper to understand the risk. The reality is that all software contains bugs. Ideally, these bugs are discovered during the development process. In practice, many of them surface only following the product release in the course of their interactions with real users. Bugs that can be exploited for malicious purposes are called vulnerabilities. Microsoft conducts rigorous and ongoing research
Latest Microsoft Update Patches New Windows 0-Day Under Active Attack

Latest Microsoft Update Patches New Windows 0-Day Under Active Attack

Dec 11, 2019
With its latest and last Patch Tuesday for 2019, Microsoft is warning billions of its users of a new Windows zero-day vulnerability that attackers are actively exploiting in the wild in combination with a Chrome exploit to take remote control over vulnerable computers. Microsoft's December security updates include patches for a total of 36 vulnerabilities, where 7 are critical, 27 important, 1 moderate, and one is low in severity—brief information on which you can find later in this article. Tracked as CVE-2019-1458 and rated as Important, the newly patched zero-day Win32k privilege escalation vulnerability, reported by Kaspersky, was used in Operation WizardOpium attacks to gain higher privileges on targeted systems by escaping the Chrome sandbox. Although Google addressed the flaw in Chrome 78.0.3904.87 with the release of an emergency update last month after Kaspersky disclosed it to the tech giant, hackers are still targeting users who are using vulnerable versions of th
Critical Flaws Found in VxWorks RTOS That Powers Over 2 Billion Devices

Critical Flaws Found in VxWorks RTOS That Powers Over 2 Billion Devices

Jul 29, 2019
Security researchers have discovered almost a dozen zero-day vulnerabilities in VxWorks, one of the most widely used real-time operating systems (RTOS) for embedded devices that powers over 2 billion devices across aerospace, defense, industrial, medical, automotive, consumer electronics, networking, and other critical industries. According to a new report Armis researchers shared with The Hacker News prior to its release, the vulnerabilities are collectively dubbed as URGENT/11 as they are 11 in total, 6 of which are critical in severity leading to 'devastating' cyberattacks. Armis Labs is the same IoT security company that previously discovered the BlueBorne vulnerabilities in Bluetooth protocol that impacted more than 5.3 Billion devices—from Android, iOS, Windows and Linux to the Internet of things (IoT). These vulnerabilities could allow remote attackers to bypass traditional security solutions and take full control over affected devices or "cause disruption on
macOS 0-Day Flaw Lets Hackers Bypass Security Features With Synthetic Clicks

macOS 0-Day Flaw Lets Hackers Bypass Security Features With Synthetic Clicks

Jun 03, 2019
A security researcher who last year bypassed Apple 's then-newly introduced macOS privacy feature has once again found a new way to bypass security warnings by performing 'Synthetic Clicks' on behalf of users without requiring their interaction. Last June, Apple introduced a core security feature in MacOS that made it mandatory for all applications to take permission ("allow" or "deny") from users before accessing sensitive data or components on the system, including the device camera or microphone, location data, messages, and browsing history. For those unaware, 'Synthetic Clicks' are programmatic and invisible mouse clicks that are generated by a software program rather than a human. MacOS itself has built-in functionality for synthetic clicks, but as an accessibility feature for disabled people to interact with the system interface in non-traditional ways. So, the feature is only available for Apple-approved apps, preventing ma
PoC Exploit For Unpatched Windows 10 Zero-Day Flaw Published Online

PoC Exploit For Unpatched Windows 10 Zero-Day Flaw Published Online

May 22, 2019
An anonymous hacker with an online alias "SandboxEscaper" today released proof-of-concept (PoC) exploit code for a new zero-day vulnerability affecting Windows 10 operating system—that's his/her 5th publicly disclosed Windows zero-day exploit [ 1 , 2 , 3 ] in less than a year. Published on GitHub , the new Windows 10 zero-day vulnerability is a privilege escalation issue that could allow a local attacker or malware to gain and run code with administrative system privileges on the targeted machines, eventually allowing the attacker to gain full control of the machine. The vulnerability resides in Task Scheduler, a utility that enables Windows users to schedule the launch of programs or scripts at a predefined time or after specified time intervals. SandboxEscaper's exploit code makes use of SchRpcRegisterTask, a method in Task Scheduler to register tasks with the server, which doesn't properly check for permissions and can, therefore, be used to set an arb

Reminder: Microsoft to end support for Windows 7 in 1-year from today

Jan 15, 2019
A new reminder for those who are still holding on to the Windows 7 operating system—you have one year left until Microsoft ends support for its 9-year-old operating system. So it's time for you to upgrade your OS and say goodbye to Windows 7, as its five years of extended support will end on January 14, 2020—that's precisely one year from today. After that date, the tech giant will no longer release free security updates, bug fixes and new functionalities for the operating system that's still widely used by people, which could eventually leave a significant number of users more susceptible to malware attacks. However, the end of free support doesn't end Windows 7 support for big business and enterprise customers. As always, Microsoft does make exceptions for certain companies that are willing to pay a lot of money to continue their support. According to a 'Death of Windows 7' report from content delivery firm Kollective, as many as 43% of enterprises
Hacker Discloses New Windows Zero-Day Exploit On Twitter

Hacker Discloses New Windows Zero-Day Exploit On Twitter

Oct 24, 2018
A security researcher with Twitter alias SandboxEscaper—who two months ago publicly dropped a zero-day exploit for Microsoft Windows Task Scheduler—has yesterday released another proof-of-concept exploit for a new Windows zero-day vulnerability. SandboxEscaper posted a link to a Github page hosting a proof-of-concept (PoC) exploit for the vulnerability that appears to be a privilege escalation flaw residing in Microsoft Data Sharing (dssvc.dll). The Data Sharing Service is a local service that runs as LocalSystem account with extensive privileges and provides data brokering between applications. The flaw could allow a low-privileged attacker to elevate their privileges on a target system, though the PoC exploit code (deletebug.exe) released by the researcher only allows a low privileged user to delete critical system files—that otherwise would only be possible via admin level privileges. "Not the same bug I posted a while back, this doesn't write garbage to files

Google Hacker Discloses New Linux Kernel Vulnerability and PoC Exploit

Google Hacker Discloses New Linux Kernel Vulnerability and PoC Exploit

Sep 28, 2018
A cybersecurity researcher with Google Project Zero has released the details, and a proof-of-concept (PoC) exploit for a high severity vulnerability that exists in Linux kernel since kernel version 3.16 through 4.18.8. Discovered by white hat hacker Jann Horn, the kernel vulnerability (CVE-2018-17182) is a cache invalidation bug in the Linux memory management subsystem that leads to use-after-free vulnerability, which if exploited, could allow an attacker to gain root privileges on the targeted system. The use-after-free (UAF) vulnerabilities are a class of memory corruption bug that can be exploited by unprivileged users to corrupt or alter data in memory, enabling them to cause a denial of service (system crash) or escalate privileges to gain administrative access on a system. Linux Kernel Exploit Takes an Hour to Gain Root Access However, Horn says his PoC Linux kernel exploit made available to the public "takes about an hour to run before popping a root shell."

Researcher Claims Samsung's Tizen OS is Poorly Programmed; Contains 27,000 Bugs!

Jul 13, 2017
A researcher has claimed that Samsung's Tizen operating system that runs on millions of Samsung products is so poorly programmed that it could contain nearly 27,000 programming errors, which could also lead to thousands of vulnerabilities. Tizen is a Linux-based open-source operating system backed by Intel and Samsung Electronics, which has been in development since early 2012 and designed for smartphones, tablets, smart TVs, smart watches, cameras and PCs. According to Andrey Karpov — founder of Russia-based company Program Verification Systems that made PVS-Studio, a static code analyzer tool that helps programmers to find and fix bugs in their source codes — his team has discovered hundreds of errors in Tizen project using PVS-Studio. Samsung's Tizen operating system, written in C/C++ programming language, currently has 72.5 million lines of source code, out of which Karpov's team has analysed some randomly chosen modules i.e. 3.3% of the entire Project and fou

Android Beats Windows to Become World's Most Popular Operating System

Apr 03, 2017
It's an impressive milestone for Google — For the first time in decades, Android has been crowned as the world's most popular operating system in terms of Internet usage, knocking Microsoft Windows off the top spot. According to a new report from web traffic analytics firm StatCounter, Google's Android is the most popular operating system worldwide in terms of total internet usage across desktop, laptop, tablet, and mobile combined. Looking at overall internet usage, Android represented 37.93 percent of the global OS Internet usage market share in March, while Windows accounted for 37.91 percent. Although Windows is still not far behind, Android taking the lead is being described by StatCounter CEO Aodhan Cullen as a "milestone in technology history." This achievement is due to the fact that mobile devices are used to connect to the Internet far more frequently than desktops and laptops, and people are spending more time on smartphones surfing the Inter
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

Mar 20, 2017
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.
