Misspell one word and you’re infected: New malware campaign fools developers on both Windows and Linux

Cybersecurity experts have highlighted the risks of typosquatting, where developers accidentally download malicious packages due to typographical errors. A report from Checkmarx reveals that attackers exploit this trust by creating counterfeit packages that can grant unauthorized access to systems. Malicious packages have been found in the Python Package Index (PyPI) and can enable remote control, posing serious threats to system integrity. Attackers employ a cross-platform strategy, mixing names from different programming environments to target unsuspecting users. On Windows, malware can create scheduled tasks and disable antivirus protections, while on Linux, certain packages facilitate encrypted reverse shells for data exfiltration. Although the malicious packages have been removed, the threat remains, prompting developers to verify package sources and spellings. Checkmarx recommends organizations conduct audits of deployed packages and scrutinize application code to enhance security.

In response, Arms Cyber has begun offering ransomware protection for macOS, becoming the first firm to provide comprehensive protection across Windows, Linux, and macOS. Their solutions include real-time file entropy analysis, Steal Archival technology for rapid recovery, and Automated Moving Target Defense (AMTD) to thwart attacks. The growing use of Mac devices in critical sectors highlights the need for enhanced security measures, as attackers see opportunities in less protected systems. Managed Security Service Providers (MSSPs) are also being equipped with these protections to strengthen defenses against ransomware.

Signal now blocks Microsoft Recall screenshots on Windows 11

Signal has introduced a "screen security" feature in its Windows application to enhance user privacy by preventing Microsoft's AI-driven Recall functionality from capturing content displayed within the app. This feature is active by default on all Windows 11 devices and sets a Digital Rights Management (DRM) flag on Signal's app windows. Recall, launched in May 2024, captures screenshots of active windows and has raised privacy concerns, leading Microsoft to make it optional and implement various security enhancements. Users can disable Signal's screen security but will be warned about potential privacy risks. Signal's developer, Joshua Lund, highlighted ongoing concerns regarding privacy in applications like Signal and called for a balance between privacy and accessibility in AI technologies.

Microsoft fixes Linux boot issues on dual-boot Windows systems

Microsoft addressed a boot issue affecting dual-boot systems running Linux alongside Windows after the August 2024 Windows security updates, which caused Linux systems to fail to boot due to a Secure Boot Advanced Targeting (SBAT) update. This issue impacted various Windows operating systems, including Windows 10, Windows 11, and Windows Server 2012 and later. The problem arose from a detection mechanism that failed to recognize some customized dual-boot setups, leading to error messages such as "Something has gone seriously wrong: SBAT self-check failed: Security Policy Violation." Microsoft confirmed that the boot issues would be resolved with the May 2025 Patch Tuesday security updates and provided a temporary workaround in late August, advising users to delete the SBAT update. On September 19, Microsoft stopped the automatic application of the problematic SBAT update and recommended a command to prevent future SBAT updates. The issue was specific to the August 2024 security and preview updates, and subsequent updates starting with September 2024 did not contain the problematic settings.

I started dual-booting NixOS alongside Windows, and I’m so glad I did

Dual-booting allows users to navigate between Windows and Linux, with NixOS being a notable Linux distribution due to its unique package management system that isolates each package in its own immutable path, preventing dependency conflicts. NixOS uses a single configuration file for system management, enabling atomic changes and easy rollbacks. Users have reported that NixOS provides a streamlined experience compared to Windows, which is often cluttered with advertisements and notifications, and feels sluggish. Daily use of NixOS is described as straightforward and enjoyable, allowing for easy customization and experimentation without the fear of disrupting the system. While some users still rely on Windows for specific applications, NixOS offers a stable and personalized environment that enhances the overall computing experience.

Intego Mac Internet Security

PCs were introduced before Apple’s Macintosh, leading to the emergence of PC viruses and the establishment of antivirus companies, with Macintosh protection being less prioritized. Intego focused on Macintosh security from the start, offering Intego Mac Internet Security, which includes a firewall that manages network permissions and defends against external attacks. Intego has been effective against Mac malware, achieving a 99.1% malware detection score in independent lab tests, although it lacks phishing protection, a feature offered by competitors Norton 360 Deluxe and Bitdefender Antivirus Plus. Intego's pricing is competitive, with a standard annual fee of .99 for a single license and .99 for three licenses. A five-device subscription costs .99, while the Mac Premium Bundle starts at .99 annually and includes additional features. A 14-day free trial is available, and free alternatives like Avast and AVG are also on the market. Intego supports older macOS versions back to Mavericks (10.9), but the latest version requires High Sierra (10.13) or later. The installation process for Intego is straightforward, requiring a restart and granting necessary permissions. The main interface includes components for updates, firewall, and antivirus, with user-friendly access to scanning options. Intego has received certification from AV-Comparatives and detected 100% of Windows malware samples in tests. Its quick scan takes about two and a half minutes, while a full system scan takes seven minutes. Intego's Safe Browsing feature checks existing browser protections but lacks a dedicated antiphishing solution. The NetBarrier firewall allows users to classify their network and manage traffic permissions effectively, although it may be complex for some users.

5 reasons why Windows isn’t the best OS for productivity

Operating systems significantly influence user interactions with computers, accommodating various preferences. Windows is the most widely used operating system for traditional desktops but has several productivity limitations: 1. Windows installations often come with excessive pre-installed applications (bloatware), unlike macOS and most Linux distributions, which have minimal bloatware. 2. Windows lacks built-in productivity software, requiring users to purchase Microsoft Office or use alternatives, while macOS includes basic applications and Linux offers LibreOffice for free. 3. Windows does not have an integrated local file-sharing solution comparable to Apple's AirDrop, making file transfers between devices more cumbersome. 4. Keyboard and touchpad shortcuts in Windows are less intuitive and consistent compared to macOS, which can hinder productivity for users accustomed to macOS gestures. 5. Windows is a primary target for malware due to its widespread use, leading to a higher risk of system compromise compared to macOS and Linux, which encounter less malware.
