Microsoft Wants to Protect Your Linux Desktop with Defender

Microsoft has expanded its Defender security software to Linux desktop environments, currently in public preview. Microsoft Defender for Endpoint is designed for organizations using Linux workstations and aims to enhance security for developers who interact with sensitive resources. Key features include real-time antivirus protection, endpoint detection and response, threat investigation, vulnerability management, and centralized security monitoring. The software uses the same deployment packages and installation methods as those for Linux servers, supporting distributions like Ubuntu LTS, Debian, Fedora, Red Hat Enterprise Linux, openSUSE Leap, SUSE Linux Enterprise, Rocky Linux, and AlmaLinux. Compatibility with desktop environments is based on the underlying distribution and kernel. The software identifies devices by assessing operating system metadata, and if it cannot classify a machine as a workstation, it defaults to identifying it as a server. This development follows the introduction of Defender for Linux servers in 2020. Organizations need a Microsoft Defender for Endpoint subscription and must meet Linux system requirements to use the software.

The summary shall NOT include a title, introduction and conclusion. Text: On October 15, Ledger unveiled its latest innovation, the “Atom,” a phone-shaped crypto cold wallet designed to enhance security in the digital currency landscape. This device allows Android-based applications to operate on a distinct system, separate from the one that authorizes transactions. Interested customers can now place reservations, with deliveries anticipated in 2027. This announcement arrives amid Ledger's ongoing efforts to address concerns regarding compromised devices that have surfaced in Southeast Asia. The Atom aims to provide an additional layer of protection against physical tampering, ensuring users can transact with confidence. Everyday apps, separate transaction approvals According to Ledger, everyday applications will function independently from the secure environment that safeguards users’ private keys. When a transaction requires approval, the device's security system takes over the display, illuminating an indicator to signal that users have entered this protected mode. This design empowers individuals to verify their actions rather than relying solely on information presented by standard applications. Moreover, the Atom features a physical switch that allows users to disable the camera and microphone, further enhancing privacy and security. Ledger updates its account of the thefts In light of recent events, Ledger has provided clarity regarding the thefts reported by AMBCrypto on October 9. The company explained that criminals may have acquired legitimate devices, modified them with hidden components, and subsequently returned them to the distribution network through resellers. These components were engineered to capture users' recovery phrases during the registration process, granting access to their wallets for anyone possessing that critical information. Despite these incidents, Ledger asserts that its crypto hardware, operating platform, and servers remain secure from hacking attempts. In response to the situation, the company has temporarily suspended its reseller and distributor sales channels in Southeast Asia and Hong Kong. The Atom is designed with a protective shield to detect any interference with its secure components, reinforcing Ledger's commitment to user safety.

Experts warn cheap Android phones are shipping with malware

Cybersecurity experts from Bitdefender have found that budget Android smartphones, such as the Doogee S200 X, Doogee Fire 3 Max, and Cubot KINGKONG X, may come pre-loaded with malware embedded in their firmware, posing significant security risks. This malware is introduced during the manufacturing process, particularly affecting devices with MediaTek chipsets. Thousands of users in around 150 countries, including Mexico, France, Italy, the United States, Germany, Brazil, and Spain, have been impacted. Bitdefender identified a network of 32 malicious applications disguised as legitimate utilities that generate fraudulent ad impressions. Some infected phones can function as residential proxies for criminal activities, including spam campaigns and DDoS attacks. Uninstalling the malicious app may not eliminate the infection if it is integrated into the system software, potentially requiring firmware-level remediation. Buyers of budget phones should research manufacturers' supply chain control and commitment to security updates.

Canada could save millions by developing its own operating system instead of relying on Microsoft Windows

Canada is focusing on digital sovereignty in sectors like cloud computing and telecommunications, but the operating systems for government computers have received less attention. A study suggests that adopting a national, free, and open-source operating system could save Canada millions over the next decade and reduce reliance on U.S. technology providers. Currently, Microsoft Windows dominates the Canadian desktop market with a 63.75 percent share, costing the government over 0 million annually. Trust in U.S. technology has declined among Canadians, with 60 percent feeling they can never trust Americans the same way again. Open-source alternatives like Linux exist, which could be adapted into a national operating system based on Debian, allowing Canada to inspect and modify the code. Other countries, such as China and Germany, have developed their own operating systems, achieving significant savings. Transitioning to an open-source system would involve costs estimated between million and million over two years, compared to Germany's ZenDiS initiative. The projected gross savings from switching operating systems over ten years could range from 0 million to .13 billion, benefiting various sectors by reducing licensing fees and enhancing national security.

Windows 11 promises to clean up bloat, but disabling its own features is the only thing that works

Upon installing Windows 11, users encounter numerous pre-installed applications, promotional tiles, and cloud-connected features. These apps are organized in two phases: system-level staging and user-specific activation. The AppX Deployment Service registers these apps for users, creating app data folders. Microsoft also embeds custom app shortcuts and trial software into the Start menu using LayoutModification.json. During setup, Microsoft's Consumer Experience feature connects to cloud servers, downloading app placeholders that are pinned to the Start menu. Local search is integrated with Bing by default, sending requests for suggestions and promoted content. To clean up Windows 11, users can uninstall non-essential applications through Settings, but this only removes them from the user profile. To permanently eliminate app templates, PowerShell commands can be used. Users can disable promotional content in Settings under Personalization and Privacy & Security. To sever Bing integration from search, modifications in the registry editor are required. The Task Manager can help manage startup applications, allowing users to disable non-essential third-party apps. While removing unnecessary components can improve performance, essential packages like Edge WebView2 runtime, Microsoft Defender, and the Microsoft Store should be retained to avoid system errors. Regular maintenance is necessary, as Windows updates may reinstall previously removed apps.

Forget Sony’s barely existent PS5 exclusives, this developer wants to turn the console into a Windows gaming machine

A developer named Mihawk has successfully run Windows 11 on the PS5 through a project called Mihawk OS, allowing both 32-bit and 64-bit Windows games to operate on a jailbroken PS5. Mihawk has also integrated RetroArch, enabling various emulators to function on the console. Early reports indicate that the game HADES has been seen running in this Windows environment. This development may allow gamers to play titles like Gears of War: E-Day natively on the PS5. However, jailbreaking the console can limit access to PlayStation servers and pose risks to user accounts.

Microsoft Warns About Windows Update Certificate Expiration

Microsoft has reminded IT administrators about the expiration of certificates that enable trusted connections between Windows devices and Windows Update servers, set to expire in May and June of 2027. Devices without replacement certificates by these deadlines may lose access to Windows Update services. Most supported Windows devices will receive new certificates automatically through security updates, but older or infrequently updated systems may require manual intervention. Organizations that do not update their devices risk losing access to critical updates, particularly unsupported Windows versions that will not receive necessary certificate updates. IT teams should audit device inventories and ensure compliance with updates, as systems on supported versions will obtain replacement certificates seamlessly. Upgrading unsupported systems is essential, and organizations are encouraged to conduct audits and expedite upgrade projects to avoid losing access to Windows Update.
