As a longtime Android privacy nerd, here are 6 privacy apps I actually regret installing

The author shares experiences with six privacy applications that did not meet expectations. 1. Private Internet Access (PIA): A robust VPN service with a cluttered interface and concerns about its U.S. base; transitioned to NordVPN for a better user experience. 2. Brave Browser: Known for ad and tracker blocking, but had issues with Brave Search reliability, syncing, and battery drain; switched to Firefox with uBlock Origin. 3. LastPass: A former leading password manager that lost trust due to security breaches; moved to Bitwarden for its solid and secure platform. 4. KeePassDX: Impressive for local storage and clean UI, but lacked cloud syncing and required manual password management; eventually chose Bitwarden for convenience. 5. OpenBoard: A privacy-focused keyboard app that is no longer available on Google Play; basic features and installation hassles led to regret over its use; better alternatives exist. 6. OsmAnd: An open-source offline navigation app with extensive customization but a steep learning curve and rigid address searches; now prefers Organic Maps for ease of use.

Microsoft patches record 198 Windows bugs in June update – and 3 are zero days

Microsoft's latest Patch Tuesday addressed 198 security vulnerabilities, the most extensive update in recent memory. Among these, 32 flaws are classified as critical, and three are zero-day vulnerabilities. The updates are detailed in KB articles: KB5094126 for Windows 11 versions 24H2 and 25H2, KB5093998 for version 23H2, and KB5094127 for Windows 10. The updates will automatically download and install, but users must verify their installation status and reboot their computers for changes to take effect. The vulnerabilities addressed this month are attributed to advancements in artificial intelligence, with companies like Microsoft leveraging AI models to expedite the identification and resolution of security flaws. The three zero-day vulnerabilities include one that allows an attacker to gain Windows System privileges through a flaw in file link resolution, another that could facilitate a denial-of-service attack via an HTTP vulnerability, and a third related to a flaw in Windows BitLocker that could enable data capture from an unpatched PC. Additionally, the update introduces new features to Windows 11, including new Secure Boot certificates, a Low Latency Profile for enhanced performance, support for shared audio devices for multiple Bluetooth connections, webcam functionality across multiple applications, and the ability to assign a custom name to the user folder during setup.

Windows 11’s June update shuts down an intentional BitLocker backdoor with full file access

Microsoft addressed three zero-day vulnerabilities identified by security researcher Nightmare-Eclipse, named YellowKey, GreenPlasma, and MiniPlasma. The YellowKey vulnerability allows access to BitLocker-protected drives on Windows 11 using a USB key, leading to allegations that Microsoft may have left a backdoor in BitLocker. Microsoft implemented a mitigation strategy included in the June 2026 Patch Tuesday updates, which addressed over 200 security flaws. Tensions arose between Microsoft and Nightmare-Eclipse regarding vulnerability reporting protocols and researcher compensation, with Microsoft initially threatening legal action against the researcher. Following backlash, Microsoft retracted the threat but tensions persisted. Nightmare-Eclipse claimed retaliation from Microsoft, including the banning of their GitHub account and deletion of their Microsoft account, which Microsoft denied. The situation highlights the ongoing challenges in cybersecurity and the relationship between tech companies and security researchers.

Apple Removes Russian State-Backed Max Messenger From App Store Amid Spyware Questions

Apple has removed the Russian state-backed messaging application, Max, from its App Store, stopping new downloads of the platform. VK, the developer of Max, confirmed this action and stated that existing users can still use the app. VK is seeking clarification from Apple and advising users to consider alternative download options. Earlier, Cloudflare had flagged Max's domain as spyware, a designation that was later lifted. The removal of Max follows a similar action against another VK service, Telega, which Apple removed after Cloudflare identified its domains as spyware. Concerns about Max's functionality as a surveillance tool have been raised, with reports of hidden features such as remote microphone recording and contact list harvesting. Since September 2025, Max has been preinstalled on new smartphones sold in Russia.

How to set up instant antivirus protection for the whole family

An antivirus program protects personal computers from malware that can steal information or disrupt operations. Antivirus vendors offer family bundles at discounted rates, allowing multiple devices to be protected under a single subscription, which can lead to significant cost savings. To set up family antivirus protection, one should choose an appropriate antivirus app based on cost, compatibility, user experience, and features. Many providers offer family plans that cover multiple devices, such as Webroot Essentials, which offers a plan for five devices at a reduced price. After selecting an app, users can opt for a free trial to assess its features before subscribing. The setup process begins with the administrator's personal device, from which family members can be invited to join the subscription. The administrator can also configure settings for connected devices, including screen time limits and web filters. Antivirus software works by scanning files against a database of malware signatures and using techniques like behavioral analysis, sandboxing, real-time web protection, and external device scans to detect threats. No single antivirus tool is the best for everyone; the choice depends on individual needs. Webroot Essentials is highlighted for its comprehensive protection, covering five devices with features like active scanning and real-time web filtering. Best practices for using antivirus tools include running only one antivirus program, enabling automatic updates, and activating real-time protection to ensure optimal security.

Android 16 Bug Allows Apps to Ignore VPNs and Leak IP Addresses

Android 16 may have a vulnerability that allows applications to bypass VPN protections, potentially exposing users' IP addresses. A security engineer reported this issue through Google’s Vulnerability Reward Program, but Google's security team deemed it "infeasible" to address. The vulnerability lies within the ConnectivityManager system service, which circumvents the VPN tunnel, leading to unencrypted traffic and exposure of sensitive information. This issue persists even with "Always-on VPN" or "Block connections without VPN" features enabled. Although there is no confirmed exploitation of this vulnerability, it poses ongoing risks for users. GrapheneOS has patched the issue, indicating a fix is possible. A debug command has been identified as a temporary workaround for affected users, but it requires caution and understanding of USB debugging mode.

Microsoft pits more than 100 AI agents against each other to find Windows vulnerabilities

Microsoft has introduced MDASH (Multi-Model Agentic Scanning Harness), a security solution that uses over 100 specialized AI agents to identify software vulnerabilities. On May 12, 2026, MDASH identified 16 new vulnerabilities (CVEs) in the Windows networking and authentication stack, four of which were critical, including remote code execution vulnerabilities in tcpip.sys, ikeext.dll, netlogon.dll, and dnsapi.dll. Ten of these vulnerabilities can be accessed over the network without authentication. MDASH operates through a four-stage pipeline: analyzing source code, scrutinizing for suspicious elements, debating the exploitability of issues, and attempting to exploit vulnerabilities. The system is model-agnostic and allows integration of new models and domain-specific knowledge. MDASH scored 88.45 percent on the CyberGym benchmark, ranking first among competitors, although the comparison may not be entirely fair as it contrasts a comprehensive framework with individual models. The models used to achieve this score are not specified. MDASH is supported by Microsoft's Autonomous Code Security Team and is currently in a limited private preview for select customers.
