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.

Windows 11’s biggest updates may need multiple reboots, but that’s normal, don’t force shutdown

Users may experience double reboots when installing substantial Windows updates, such as the April and July 2026 Updates, due to factors like Secure Boot and .NET Framework updates. The July 2026 .NET Framework update specifically requires a separate reboot. Microsoft is still rolling out the Secure Boot 2023 certificate update, which may also lead to multiple reboots. Users are advised not to panic during these reboots and to allow the system time to complete the installation process. Additionally, Microsoft has warned against delaying updates for more than three days due to increasing update sizes related to security vulnerabilities. Some users may encounter SCEP certificate errors in the Event Viewer after the July 2026 Update, but these errors do not indicate a failure of the update process.

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.

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.

Study of 281 Free Android VPN Apps Finds Traffic Leaks, Unencrypted Data, and Tracking

Researchers analyzed 281 popular free VPN applications on the Google Play Store and found significant privacy and security shortcomings. The study, conducted by teams from the University of Michigan, the University of New Mexico, and IIT Delhi using a framework called MVPNalyzer, revealed that flagged apps had over 2.4 billion downloads. Key findings included: - Five apps transmitted configuration files unencrypted, allowing attackers to intercept and modify them. - 29 apps allowed user traffic to leak outside the encrypted tunnel, with 24 leaking DNS traffic and six leaking full browsing traffic. - 169 apps made no effort to disguise their traffic, making it identifiable to network operators or government censors. - 76 apps transmitted the device's Advertising ID to advertisers, and over 80% contacted known advertising and tracking servers. - Only one of 108 OpenVPN configurations adhered to recommended security practices; 89% used a single authentication method, and nearly 20% employed outdated encryption techniques. - Many apps passed through Play Store checks without adequate scrutiny, with safety labels often serving as marketing tools rather than security indicators. These findings align with previous research highlighting similar issues in popular Android VPN apps. Users are advised to be cautious when selecting VPNs, prioritizing those with recent independent security audits.

Layered Security Essentials: Protect Your Devices from Threats

Safeguarding modern devices requires a multifaceted security strategy that includes antivirus software, VPNs, strong authentication methods, and regular system updates. Layered security combines multiple protective measures such as encryption, malware detection, and authentication controls to address diverse threats. Key elements of solid cyber hygiene include strong passwords, timely software updates, phishing awareness, and multi-factor authentication. Network protection is crucial, especially when using public Wi-Fi; users should verify the presence of encryption indicators like "HTTPS" before sharing personal information. Employing WPA3 encryption on home routers and changing default admin credentials are essential safeguards. Regular updates to operating systems and applications help close known vulnerabilities, while safe browsing habits are necessary to avoid potential threats. Antivirus software and anti-phishing tools offer real-time monitoring, and device encryption protects data in case of loss or theft. Regular backups are vital to prevent data loss from ransomware attacks or hardware failures. Phishing-resistant multi-factor authentication and passkeys provide strong defenses against credential-based attacks.
