Generating Referentially Consistent Synthetic Test Data for PostgreSQL in .NET Application Modernization

Satyajit Gokhale, Aiswaryaa Venugopalan, Ruchi Agarwal, Nits Jeganathan, Khurram Khawaja, Vijay Mandadi, and Luke Huan contributed to this article. AWS Transform offers a .NET application modernization service that allows enterprise customers to migrate from Microsoft SQL Server to Amazon Aurora PostgreSQL Compatible Edition. This migration reduces licensing costs and enhances scalability while utilizing an open-source ecosystem. Schema conversion tools can assist in translating DDL to PostgreSQL-compatible definitions, but correctness must be verified by teams to ensure performance under real-world workloads. Traditional testing methods, such as using production data or manual checks, are not scalable and raise privacy concerns. Therefore, there is a need for realistic synthetic data generated at scale that adheres to the migrated schema's constraints. AWS Transform for SQL Server modernization employs an AI agent to generate constraint-respecting synthetic data at scale during the migration workflow. This process involves loading the PostgreSQL schema into a live database, constructing a dependency graph for data generation, and distributing tasks across multiple sub-agents. The agent validates each generated INSERT against the live database, ensuring compliance with constraints and providing error diagnostics for any violations. The synthetic data generation workflow consists of four stages: schema analysis, establishing generation order, distributing tasks across sub-agents, and validation with error recovery. The agent extracts metadata from the PostgreSQL schema, determines a valid table generation sequence, parallelizes data generation while maintaining referential integrity, and generates and validates data row-by-row against the live database. Each successful insertion enriches the context for subsequent generations, while errors are handled through structured diagnostics and iterative regeneration. The process ensures referential integrity and preserves the generation state, allowing for recovery from interruptions without data loss.

ClamAV Setup: Linux Antivirus in 12 Steps [2026]

Malware can threaten Linux systems, which are often mistakenly believed to be immune to viruses. It can be introduced through email attachments, infected files, or compromised plugins, especially when Linux servers interact with Windows clients or handle internet uploads. ClamAV is an open-source antivirus engine maintained by Cisco Talos, designed for scanning mail traffic and file uploads. As of mid-2026, the stable release is ClamAV 1.5.x, with version 1.5.2 being the latest patch. To deploy ClamAV, users need root or sudo access on a compatible Linux machine, at least 2 vCPUs and 2GB of RAM, 5GB of free disk space, and outbound HTTPS access to ClamAV’s signature mirrors. The installation process involves several steps, including configuring freshclam for automatic updates, validating detection with the EICAR test file, and setting up cron jobs for regular scans. ClamAV can also be integrated with mail servers and a SIEM for enhanced security. Common pitfalls in deployment include skipping the initial freshclam run and using clamscan instead of clamdscan for repeated scans. ClamAV is free for commercial use and can also scan Windows systems, although it does not replace comprehensive endpoint protection solutions.

I Built My Second ETL Pipeline. This Time, I Started Thinking Like a Data Engineer

The author transitioned from a data analyst role to a data engineer, creating a 12-month self-study roadmap focused on learning by building projects. The first project was a GitHub ETL pipeline, which evolved from a simple Python script to a more complex system using SQLite and GitHub Actions for automation. The author realized that the challenges of data engineering lay in system design and orchestration rather than just writing ETL logic. For the second project, the author built an automated RSS ingestion pipeline to explore engineering decisions in creating a reliable data pipeline. The project emphasized the importance of separating application responsibilities from orchestration tasks, leading to the use of Docker for consistent execution environments and Kestra for orchestration. The author validated each component of the project incrementally: first the Python ETL, then PostgreSQL, followed by Docker, and finally Kestra. This approach ensured that each layer functioned correctly before adding complexity. The final architecture included distinct responsibilities for each component: Python for data processing, PostgreSQL for data storage, Docker for execution, and Kestra for orchestration. The author learned that effective engineering involves considering system reliability, error handling, and observability, shifting the focus from merely writing code to designing entire systems. The experience transformed the author's mindset, emphasizing the importance of incremental building and the separation of execution and orchestration responsibilities.

Enable BitLocker on Windows 11: 11 Steps, 45 Min [2026]

A stolen laptop can lead to a significant data breach, particularly when taken from public places. Windows 11 has introduced BitLocker, a full-disk encryption feature that became mandatory for Australian businesses in 2026. The Office of the Australian Information Commissioner reported 766 notifiable data breaches in the latter half of 2024, with unauthorized access to devices being a major cause. Full-disk encryption is crucial for compliance with the Essential Eight framework, which mandates data protection on portable devices. BitLocker ensures that data on an encrypted drive becomes unreadable if the drive is removed and connected to another computer. It aligns with the Essential Eight framework, requiring evidence of encryption rather than just claims of protection. There are three types of encryption on Windows 11: Device Encryption, BitLocker Drive Encryption, and File-Level Encryption. BitLocker is available only on Windows 11 Pro and higher editions. To use BitLocker, certain prerequisites must be met, including having Windows 11 Pro or higher, a Trusted Platform Module (TPM) 2.0, UEFI firmware with Secure Boot enabled, and local administrator rights. The process to enable BitLocker involves confirming the edition, checking TPM status, enabling BitLocker through Windows Settings or PowerShell, and backing up the recovery key. Organizations can deploy BitLocker fleet-wide using Microsoft Intune, and additional security measures like TPM+PIN can be implemented for pre-boot authentication. Common pitfalls during BitLocker rollout include skipping recovery key backup and assuming that Home edition machines are covered. Troubleshooting common BitLocker issues involves identifying symptoms and applying appropriate fixes. Advanced tips for enhancing security include suspending BitLocker before maintenance and auditing compliance at the fleet level. BitLocker is integral to protecting data on portable devices, and compliance documentation is essential for proving that every device has an active recovery key.

LabubaRAT malware infiltrates Windows systems while posing as NVIDIA software

LabubaRAT is a newly identified Rust-based remote access tool (RAT) that disguises itself as NVIDIA software to facilitate operations on Windows systems. It establishes a reusable foothold for hands-on activity and can profile the host system, identify security tools, execute commands, transfer files, capture screenshots, and proxy network traffic. LabubaRAT retrieves its configuration at launch via command-line arguments or environment variables, allowing operators to specify parameters like the command-and-control server and API key at runtime. It maintains local state in a SQLite database and supports communication through HTTPS polling, Microsoft Edge WebView2, and DNS tunneling. The malware includes capabilities for command execution, file handling, and establishing persistence through a Windows Run registry key. The entry point for the attack is an executable named nvidia-sysruntime.exe, which masquerades as NVIDIA’s container runtime toolkit. LabubaRAT conducts thorough profiling of the host, checking for installed browsers and security products, and gathers information on the system's specifications. Blackpoint Cyber has shared indicators of compromise to help detect LabubaRAT activity.

Microsoft denies WSL 3 exists, reveals Windows 11’s WSL Containers ship next week

Microsoft has clarified that there is no WSL 3 in development, as stated by Craig Loewen, the Product Manager for the Windows Subsystem for Linux (WSL). The confusion arose from articles discussing a new feature called WSL Containers, which will be launched soon. WSL allows users to run Linux environments on Windows without dual-booting, while WSL Containers enable the creation and management of Linux containers directly within Windows, eliminating the need for third-party tools like Docker Desktop. WSL 1, introduced in 2016, served as a translation layer for Linux system calls, and WSL 2, launched in 2019, included a full Linux kernel in a lightweight virtual machine. WSL Containers is an enhancement to WSL, allowing developers to build, run, and deploy containers directly from Windows using the wslc.exe command. This feature is part of Microsoft's strategy to make Windows a more accessible platform for running Linux workloads, helping to retain developers who might consider switching to other operating systems.
