Amazon RDS Proxy now supports TLS 1.3 for connections to Amazon Aurora PostgreSQL and RDS for PostgreSQL database instances, enhancing security with stronger cryptographic algorithms and a streamlined handshake process. The Proxy automatically negotiates the highest security level during connection setup and can be configured to enforce TLS 1.3 exclusively. TLS 1.3 support is also available for RDS Proxy for MySQL engines. RDS Proxy is a fully managed database proxy that improves performance, reliability, scalability, and security for RDS and Amazon Aurora databases.

Thousands of PostgreSQL servers are being hijacked to mine crypto

Researchers at Wiz have identified a cryptojacking campaign by a group called JINX-0126, targeting over 1,500 misconfigured PostgreSQL servers by exploiting weak login credentials. The attackers deploy the XMRig-C3 miner to mine Monero, consuming nearly all computing resources and increasing electricity usage for victims. Each compromised device is assigned a unique mining worker for tracking. The campaign has evolved to include defensive measures and fileless deployment to evade detection. Nearly 90% of cloud environments host PostgreSQL instances, with about one-third publicly accessible, highlighting security vulnerabilities.

Google made a dashcam app for cars with Android Automotive, but you can’t download it

Google has launched a dashcam application for Android Automotive that allows vehicles with built-in cameras to record their surroundings. This open-source app can be integrated by car manufacturers, addressing the gap where many vehicles lack a native dashcam feature. The app is designed to work with existing camera hardware and requires system-level permissions for integration into the vehicle's operating system. Recordings are stored in the vehicle's internal storage, but Google recommends saving them on external removable storage to reduce wear on internal components. Manufacturers can customize various parameters of the app, including storage allocation and user interface.

Announcing Windows 11 Insider Preview Build 26200.5516 (Dev Channel)

Windows 11 Insider Preview Build 26200.5516 (KB5054687) has been released to the Dev Channel. The Dev Channel has transitioned to the 26200 series builds, closing the opportunity to switch to the Beta Channel. The 26200 series is based on Windows 11, version 24H2. Enhancements to Windows Search for AMD and Intel®-powered Copilot+ PCs include semantic indexing for more intuitive searches, allowing users to find documents, photos, and settings using natural language. Users can manage indexed locations in Settings and the feature supports multiple languages and document formats. The improved Windows Search can also locate cloud-stored photos, with users needing to sign into OneDrive for access. A new feature called speech recap has been introduced in Narrator, allowing users to track what has been spoken and providing quick access to the last 500 strings spoken. A streamlined UI for unexpected restarts is being previewed. The Copilot can now be launched with Win + C, and users can personalize their experience through Settings. Click to Do is available from the Start menu and supports intelligent text actions in multiple languages. The Windows share window now includes a visual preview for shared links and image editing capabilities. Several fixes have been made to improve performance and address issues in Taskbar, File Explorer, Login and Lock, Windowing, and Settings. Known issues include problems with Recall and File Explorer crashes for some users. Windows Insiders in the Dev Channel receive updates based on Windows 11, version 24H2, and feature rollouts are monitored for feedback.

Why SQL Server Is Still Worth It — Redmondmag.com

SQL Server Enterprise Edition costs approximately ,000 per CPU core, with an additional 23 percent for Software Assurance. SQL Server provides a mature solution for high availability and backups, integrating seamlessly with Windows Server Failover Clustering. PostgreSQL offers three primary backup methods: SQL dump, file system-level backup (requiring database shutdown), and continuous archiving, with the latter being complex to implement. SQL Server typically offers more integrated features out of the box, such as temporal tables and graph databases, while PostgreSQL requires extensions. SQL Server caches execution plans, which can reduce CPU usage but may lead to suboptimal plans. SQL Server Management Studio (SSMS) provides a superior user experience compared to PGAdmin. SQLPackage for SQL Server is considered better than available options for PostgreSQL, and the SQL Server community is noted for its support and engagement.

Microsoft’s ReFS file system resurfaces in latest Windows 11 build

Microsoft's Resilient File System (ReFS) was introduced in 2012 with Windows Server 2012 and has been relatively obscure compared to NTFS. It has recently emerged as an optional feature in a preview build of Windows 11 (Build 27823), allowing users to format partitions with a "Flexible Storage" option, offering a choice between NTFS and ReFS. ReFS is designed for larger storage capacities, can format partitions up to 35 petabytes, and supports single files as large as the entire volume. It includes advanced features like block cloning and file-level snapshots but lacks support for certain NTFS functionalities such as bootable volumes and file compression. Currently, ReFS is primarily aimed at enterprise and server environments, but its inclusion in Windows 11 may indicate plans for broader consumer access. The open-source community is developing unofficial documentation for ReFS, and Paragon Software has created a closed-source ReFS driver.

Microsoft launches new Windows 11 apps to make it easier to find contacts and files

Microsoft has unveiled two new companion apps for Windows 11 users: People and File Search. The People app enhances connectivity by allowing users to explore contacts, access profile cards, send messages via Teams, and search based on various criteria. The File Search app simplifies file management by enabling users to find recently opened files, search by content, filter by type, and preview files before sharing. Both apps integrate with Microsoft 365 tools and can be pinned to the taskbar for easy access. Currently, they are available to Windows 11 users who have Microsoft 365 desktop apps, are part of the Microsoft 365 Insider program (Beta Channel), and hold a Microsoft 365 subscription for business.
