Tor VPN Beta brings isolated app-by-app Tor routing to Android

The Tor Project has launched Tor VPN Beta for Android, allowing mobile applications to route traffic through the Tor network, expanding beyond web browsing. This development was driven by user demand for privacy tools to bypass internet censorship, particularly in restrictive regions. The concept originated in 2021, and after initial testing and user feedback, the beta was announced on September 9. Tor VPN creates a separate Tor circuit for each application, enhancing privacy by complicating activity correlation across apps. Users can select which applications use Tor, and the interface has been improved for easier management. The beta version 1.4.0 includes support for WebTunnel bridges to disguise Tor connections as standard encrypted traffic. Usability testing revealed issues with exit-node selection, leading to a design change that requires users to connect to Tor before choosing an exit. Tor VPN is built on the Arti implementation of the Tor protocol and the Onionmasq networking layer, ensuring stability and component sharing. The software supports reproducible builds and is available via F-Droid and APK downloads. A security review in June 2025 found no major flaws but identified some issues being addressed. Tor VPN is currently in beta and focuses on enhancing circumvention capabilities and usability rather than competing with commercial VPNs on speed. Users in censored areas are advised to configure bridges for access.

12-Year-Old PostgreSQL Vulnerability Enables Database, Server Takeover

A significant vulnerability in PostgreSQL, tracked as CVE-2026-6471, has been identified by cybersecurity firm Cyera. This flaw, present since 2014, allows attackers with minimal privileges to potentially take control of databases and servers. The vulnerability, known as PostGREShell, has a CVSS score of 7.2 and can be exploited for remote code execution and privilege escalation due to a missing authorization in the database's logical decoding mechanism. Attackers with 'Replication' privileges can load arbitrary files through the logical decoding plugin, executing code with the privileges of the postgres system user. This can lead to the elevation of privileges to superuser status, granting unrestricted access to all tables and the ability to execute operating system commands. All PostgreSQL versions from 9.4 to 18 are affected, with a patch available in versions 18.6, 17.11, 16.15, 15.19, and 14.24. Organizations are advised to update their PostgreSQL instances and audit their Replication accounts.

Microsoft preps this year’s Windows 11 feature tweaks: 26H2 hits Release Preview

Microsoft has introduced Windows 11 26H2 into the Windows Insider Release Preview Channel, coinciding with the rollout of August's preview update. This version shares its servicing branch with previous versions 24H2 and 25H2. Notable features in the August Preview Update include a movable taskbar, expanded Start Menu customization options, and the ability to exclude web and Microsoft Store suggestions from local search results. The update is delivered through an enablement package, allowing activation of already downloaded functionalities without a complete OS overhaul. Windows 11 26H2 resets the support timeline, offering 24 months of support for Home and Pro editions and 36 months for Enterprise and Education editions. Enterprises need to validate this release, but compatibility with 25H2 and 24H2 is expected. Microsoft advises organizations to test compatibility with their applications and infrastructure. The company has adopted a more cautious approach to updates since the problematic Windows 10 October 2018 update. The August Preview Update faced some criticism from users reporting issues, but Microsoft claims it is not aware of any significant problems.

Windows XP’s most famous pirated key wasn’t a hack, and a Microsoft engineer explains why

The FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8 key is a notorious Windows XP product key that became widely associated with the operating system, which was released on October 25, 2001. Unlike modern free upgrades, Windows XP required users to purchase a physical copy, making the product key essential for installation. The FCKGW key was a legitimate Volume License Key that was misappropriated and allowed users to bypass Microsoft's Windows Product Activation (WPA) system, which linked product keys to specific hardware to combat piracy. This key was whitelisted in the activation logic, enabling installations without activation prompts. Although it is still technically usable on older discs, Microsoft's servers no longer validate it, and the key has been blacklisted. Microsoft recently released a new version of the Windows Bliss wallpaper to commemorate the 25th anniversary of Windows XP.

Windows XP’s most famous pirated key wasn’t a hack. It was a leak

The product key FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8 was originally intended as a valid Volume Licensing Key (VLK) for corporate use and was never meant for casual home users. It was created to facilitate developers' work by allowing them to bypass certain restrictions during testing. The key was later bundled with special volume media and disseminated online, leading to widespread misuse. Windows Product Activation (WPA) generated a unique hardware ID based on the user's CPU, RAM, and other components for validation. The FCKGW key was whitelisted in Windows XP's activation logic, allowing installations to bypass the activation prompt entirely. This oversight enabled Windows XP to function fully without the constraints of a 30-day timer or watermark and bypassed initial validation checks for updates.

How to Protect Against Ransomware: 13 Steps [2026]

Global ransomware attacks increased by 0.8% quarter-over-quarter in Q2 2026. The group Qilin has 279 confirmed victims, maintaining its position as the leading threat actor for four consecutive quarters. The rival group The Gentlemen saw a 62% increase in victims, reaching 269. Checkpoint Research's report indicates a shift in the ransomware landscape, challenging the narrative of declining attacks. IBM's analysis shows breaches within supply chains and third-party vendors have quadrupled over the past five years. Effective ransomware protection requires administrative access to endpoints, firewalls, and backup systems, along with specific software versions and tools. The 3-2-1-1-0 backup strategy is recommended, emphasizing offline, immutable backups. Organizations should implement multi-factor authentication (MFA) across all access points and actively patch known vulnerabilities. Network segmentation is crucial to limit ransomware spread, and canary files can provide early warnings of attacks. Regular phishing simulations and a well-documented incident response plan are essential for preparedness.

Microsoft Prepares Windows Code Signing for Stronger Cryptography

Microsoft has issued an advisory to IT teams and software developers regarding significant changes in Windows code signing due to the expiration of the Windows Production PCA 2011 certificate in October 2026. The transition will involve stronger cryptographic algorithms, including RSA-3072 and SHA-384, which may cause compatibility issues for applications that rely on hardcoded certificate checks or outdated cryptographic standards. Microsoft plans to implement post-quantum cryptography by default for Windows code signing in 2027. IT administrators are encouraged to assess their software environments, confirm vendor compliance with supported trust-validation mechanisms, and ensure applications are tested against the new certificate hierarchy and signing algorithms. Organizations with private trust stores must establish processes for recognizing and deploying legitimate Microsoft certificate updates.

Microsoft is updating Windows Production CA, IT admins and devs should take action ASAP

Microsoft is updating its Windows certificate framework, focusing on Secure Boot certificates and the expiration of certain Windows 11 Insider certificates. A new certificate update is crucial to prevent disruptions in applications and IT processes. Microsoft is phasing out outdated certificates and modernizing signing algorithms, with the Windows Production Public Certificate Authority (PCA) 2011 set to expire on October 19, 2026. It will be replaced by a new PCA, and stronger signing algorithms like RSA-3072 and SHA-384 will be adopted later this year. Applications relying on outdated technologies may fail due to these updates. IT administrators and application developers are advised to review software, adopt algorithm-agnostic approaches, test certificate changes, and check private trust stores for issues. The timeline includes the PCA expiration in 2026, a transition to stronger configurations later that year, and a default to post-quantum cryptography (PQC) in 2027, with ongoing updates as security needs evolve.
