Meet Xata Agent: An Open Source Agent for Proactive PostgreSQL Monitoring, Automated Troubleshooting, and Seamless DevOps Integration

Xata Agent is an open-source AI assistant designed for PostgreSQL database site reliability engineering. It monitors logs and performance metrics to identify issues like slow queries and unusual connection counts, helping to maintain database integrity and performance. The tool automates tasks such as vacuuming and indexing and provides actionable recommendations through diagnostic playbooks and read-only SQL routines. The architecture is built as a Next.js application using TypeScript, organized in a monorepo structure. Developers can set up their environment using Node, install dependencies, and configure a local PostgreSQL instance with Docker Compose. Production deployment involves using Docker images and configuring environment variables in a production file. Key functionalities include proactive monitoring, configuration tuning, performance troubleshooting, safe diagnostics, cloud integration, alerting, LLM flexibility, and playbook customization. Developers can create new tools and integrate them into playbooks for cohesive workflows. Future plans include custom playbooks, support for Model Context Protocol, evaluation harnesses, approval workflows, and a managed cloud edition. The architecture promotes extensibility and community contributions, standardizing incident response and reducing human error in database management.

Malware steals bank cards and passwords from millions of devices

Infostealer malware has become a major cybersecurity threat, with around 25 million users targeted between early 2023 and the end of 2024. These malware variants capture sensitive information, including bank card details and passwords, with nearly 26 million devices affected during this period, resulting in over 2 million unique bank card details leaked. One in every 14 infections compromised bank card data, passwords, and second-factor authentication cookies. In 2024, infections increased significantly, with RisePro's share rising from 1.4% to 22.45% and Stealc from 2.65% to 13.33%. Redline remained the most prevalent infostealer, responsible for 34.36% of infections. By August 2024, an estimated 15.9 million devices had been affected in 2023, increasing to 16.49 million by March 2025. Over 9 million infections were tracked in 2024, with final counts expected to exceed those of 2023. To protect sensitive information, it is recommended to invest in robust antivirus software, use virtual cards for online transactions, set up transaction alerts and spending limits, avoid storing card details in browsers, use strong and unique passwords, and consider personal data removal services.

I never click any link on my Android phone without using this app first

URLCheck is an open-source application for Android that enhances link management by intercepting links before they are followed, allowing users to view, modify, or disregard them. It integrates with the VirusTotal API for threat checking, although users must sign up to use this feature. The app removes tracking tags and unnecessary redirects when sharing links. To set up URLCheck, users need to download it, select it as the default browser, and enable preferred modules. While URLCheck improves security, it does not guarantee complete safety online and requires users to exercise caution. The app only intercepts links from applications that redirect to a browser, and users must use the share menu to check URLs within their browser.

“Reinventing the Wheel: New Computing Concepts Using Windows NT Architecture and PowerShell”

The Windows NT architecture continues to support a significant portion of global IT infrastructure, with millions of installations across Windows Server, Windows 10, and Windows 11. It can be leveraged alongside modern PowerShell techniques to create next-generation computing solutions. A secure and distributed file system can be implemented using Windows NT's Distributed File System (DFS) with encryption capabilities through PowerShell scripts. This allows organizations to create a secure, fault-tolerant file-sharing mechanism. PowerShell scripts can also be used to establish a real-time health monitoring dashboard that aggregates data from event logs, system performance counters, and custom triggers, enabling system administrators to swiftly identify failures and monitor system health. Automating patch management can be achieved through PowerShell by utilizing Windows Update Services (WSUS) to streamline the detection of missing updates, apply patches, and audit systems for compliance. PowerShell can enhance identity and access management (IAM) processes by automating compliance and monitoring permissions, ensuring continuous auditing of user access rights and adherence to corporate policies.

Choosing the right secure messaging app for your organization

Liad Shnell, the Chief Technology Officer at Rakuten Viber, discussed key factors organizations should consider when selecting secure messaging applications. Important features include end-to-end encryption, global accessibility, integration capabilities, AI-driven extensibility, and privacy standards like SOC 2 Type 2 and GDPR compliance. To mitigate phishing and malware risks, users should exercise caution with links and verify sender identities. Leading platforms like Viber implement security measures, such as filtering messages from unknown senders and using algorithms to block suspicious activities. The SANS 2024 Security Awareness Report indicates that 89% of respondents view social engineering attacks as a primary concern, emphasizing the need for security awareness programs, clear communication policies, and AI-driven detection tools. Balancing usability and security is essential, with a focus on user experience through AI-driven automation and zero trust principles. Emerging trends include post-quantum cryptography and enhanced AI detection capabilities to maintain authenticity in conversations as technology evolves.
