Can Chromebooks Get Viruses? How to Protect Your Device

Chromebooks are designed with robust security features, including sandboxing, Verified Boot, automatic updates, data encryption, and Recovery Mode, which collectively reduce the risk of malware infections. However, they are still vulnerable to threats such as malicious Chrome extensions, scam Android apps from third-party stores, phishing attacks, and risks associated with using Developer Mode and cloud storage. Users can identify potential malware through signs like slow performance, unexpected pop-ups, and unusual battery drain. To remove malware, users should eliminate suspicious extensions, uninstall dubious apps, run antivirus scans, enable Google Play Protect, or perform a Powerwash to reset the device. To protect their Chromebooks, users should avoid Developer Mode, check app permissions, use two-factor authentication, verify website URLs, and use a VPN on public Wi-Fi.

How to Install Messaging Apps Safely on Windows PCs and Android Devices

Messaging applications are widely used for communication across various platforms, including Windows PCs and Android devices. Users often install these apps on both types of devices to facilitate conversations. The installation process requires careful consideration of the app's source, compatibility, permissions, and avoidance of counterfeit installers. Before installation, users should verify the app's source for transparency and security, ensuring it is from a trusted provider and appropriate for their device. For Windows users, a checklist includes confirming system compatibility, verifying the installer, and reading installation screens carefully. Android users should also confirm the app's source, check permissions, and avoid suspicious APK files. Fake installers and unsafe APKs pose risks, as they can contain modified versions of apps that compromise security. Users should be cautious of misleading download pages and links shared in online groups. Keeping messaging apps updated is essential for performance and security, and users should manage updates from trusted sources. Before logging into a messaging app, users should ensure it was downloaded from a reliable source, verify the file's compatibility with their device, review permissions, and safeguard verification codes. After logging in, users should check active sessions and remain vigilant against suspicious links and files.

Your free VPN on Android often offers less protection than you might think

The MVPNalyzer Study conducted by researchers at the University of Michigan analyzed various VPN services, focusing on their performance metrics, data privacy practices, and effectiveness in bypassing geographical restrictions. The study revealed that some VPNs excel in speed while others prioritize security features, and not all services provide the same level of data protection, with certain logging practices raising concerns. The findings encourage users to closely examine VPN services regarding speed, privacy policies, and data management, while urging VPN providers to improve transparency and invest in user security technologies.

Windows 11 Has a Hidden Tracker – Here’s How to Limit It

Peter Stokes allegedly used sophisticated methods to obscure his identity during a breach at a luxury retailer, but the FBI uncovered his identity through a Global Device Identifier (GDID) linked to his Windows installation. GDID is a persistent device-level identifier that uniquely identifies a Windows installation and remains unchanged through operating system updates, only resetting upon complete reinstallation. Users cannot disable GDID, and attempts to remove it may disrupt Windows activation. To minimize data associated with GDID, users can opt for a local account, limit diagnostic telemetry, disable Activity history, and be cautious during reinstallation. VPNs do not prevent Microsoft from logging GDID, IP addresses, and URLs, making them ineffective for privacy on Windows. GDID has been described as a covert tracking beacon, and security experts advise against using Windows for sensitive tasks, suggesting alternatives like Linux.

Windows 11 Has a Hidden Tracker – Here’s How to Limit It

Peter Stokes is involved in a breach with a luxury retailer, using tactics like VPNs and rotating IP addresses to hide his digital activity. The FBI discovered a Global Device Identifier (GDID) linked to his Windows installation, which is a persistent device-level identifier that uniquely identifies Windows installations. GDID remains unchanged through operating system updates but resets with a full reinstallation. Disabling GDID is not possible, as attempts to do so would disrupt Windows activation. Users can minimize data linked to GDID by using a local account, reducing diagnostic telemetry, disabling Activity history, and carefully managing reinstalls. VPNs do not prevent Microsoft from logging GDID, IP address, and URL data. Privacy researchers view GDID as a covert tracking mechanism, and Windows lacks user-facing options to reset this identifier, unlike Apple and Google.

GigaWiper: Anatomy of a destructive backdoor assembled from multiple malware

Microsoft Threat Intelligence has identified the GigaWiper malware, which has been detected in compromised environments since October 2025. This malware has destructive capabilities and comes in two forms: standalone wiper binaries and larger binaries with backdoor functionalities, both developed in Golang. The standalone wiper operates at the physical disk level, overwriting disk content and removing partition references. The backdoor variant includes the same wiper functionality and adds persistence through a registry key and scheduled tasks, along with command and control communication via RabbitMQ and Redis. GigaWiper can execute various commands, including wiping drives, triggering a Blue Screen of Death (BSOD), file encryption that mimics ransomware behavior, and managing system elements. The malware integrates components from multiple malware families, including wipers and ransomware mechanisms, and has been linked to a previous malware known as FlockWiper. To defend against GigaWiper, organizations are advised to implement security measures such as tamper protection, blocking access to known C2 infrastructure, and utilizing endpoint detection and response solutions. Microsoft Defender provides detections for GigaWiper and related malware, and threat intelligence reports are available for customers to stay informed about threats. Indicators of compromise include specific SHA-256 hashes and IP addresses associated with GigaWiper.

GDID Windows – Cut the tracker that follows you even through a VPN

In April 2026, the FBI apprehended an individual associated with the Scattered Spider group, who had concealed his online activities using a VPN. His efforts were thwarted by the GDID, a 64-bit Persistent Unique Identifier assigned by Microsoft upon logging into Windows. The GDID is stored in plain text in the registry and is linked to Microsoft’s servers, remaining unaffected by changes to IP addresses or attempts to delete it. Disabling Windows telemetry does not prevent the GDID from being accessed, as it operates through other services. To mitigate its transmission, users can disable certain services and modify the hosts file, although the GDID itself remains stored on Microsoft’s servers. Scripts are available on GitHub to audit and implement changes regarding the GDID. Transitioning to a local account does not guarantee anonymity, and for sensitive activities, using a live Linux system is recommended for better data control.
