One-click Postgres Pro optimization with pgpro_tune

pgpro_tune is a command-line utility designed to optimize the initial server configuration of Postgres Pro based on hardware specifications. It scans the server to identify key hardware details, processes these values through shell scripts that encapsulate tuning expertise, and generates recommended parameters for PostgreSQL settings, including memory management, autovacuum tuning, connection limits, and statistics collection. The utility appends these settings to the postgresql.conf file, ensuring they override the default settings. pgpro_tune supports various presets for different use cases and allows database administrators to create custom presets. It runs automatically during cluster initialization and can be executed manually at any time, applying changes through standard PostgreSQL methods. This tool aims to streamline the tuning process, reduce the risks of misconfiguration, and enhance performance without replacing the need for advanced tuning in specialized scenarios.

Chimera Malware: Outsmarting Antivirus, Firewalls, and Human Defenses

X Business, an e-commerce store specializing in handmade home décor, experienced a cybersecurity incident involving a malware strain called Chimera. The attack began during a routine update to their inventory management system and escalated within 12 hours, resulting in halted customer orders, locked employee accounts, and a crashed website. The attackers demanded a ransom of 0,000 in cryptocurrency, threatening to expose sensitive customer data. Chimera is an AI-driven malware that adapts its code to evade detection, targeting both Windows and macOS systems. It exploited a zero-day vulnerability in Windows' Print Spooler service and bypassed macOS security measures by forging code signatures. The malware used social engineering tactics to deceive employees into activating malicious payloads, leading to compromised systems and encrypted customer data. The recovery process took 48 hours, utilizing cybersecurity tools like CrowdStrike Falcon and SentinelOne Singularity to identify and isolate the malware. Data restoration was achieved through Acronis Cyber Protect and macOS Time Machine, while vulnerabilities were addressed with Qualys and emergency patch deployment via WSUS. The network security framework was improved using Cisco Umbrella and Zscaler Private Access to implement a Zero Trust architecture. The incident highlights the need for small enterprises to adopt proactive cybersecurity strategies, including a 3-2-1 backup approach, Zero Trust models, investment in AI-driven defense tools, and employee training to recognize social engineering attempts.

5 reasons why I stopped using an antivirus on Windows 11

A growing number of users are reevaluating their reliance on traditional antivirus software, reflecting a deeper understanding of personal security needs. Many individuals are adopting strong cyber hygiene practices, taking personal responsibility for safe browsing and cautious online behavior. Modern browsers like Opera and Brave offer built-in security features and VPNs, emphasizing self-discipline in cybersecurity. Microsoft Defender Antivirus, integrated into Windows 11, provides real-time protection and frequent updates, making it a reliable choice for users who practice basic cyber hygiene. High-end antivirus packages often come with subscription fees, while open-source solutions can be cost-effective alternatives. Users have reported improved system performance after moving away from third-party antivirus programs, experiencing faster boot times and increased responsiveness. Essential security features are now recognized as not exclusive to antivirus software, with regular data backups, encryption, and password management enhancing overall protection. While some users find sufficient protection without traditional antivirus software, others with different threat models may still require it.

Photo appears to shows Mike Waltz using Signal-like app that can archive messages

White House Deputy Press Secretary Anna Kelly confirmed that the encrypted messaging application Signal is officially sanctioned for government use and installed on government-issued devices. The National Security Council has not commented on the related app, TeleMessage, which is derived from Signal and designed to help government entities comply with records retention laws. TeleMessage was founded in 1999, acquired by Smarsh in 2024, and has been involved in government contracts, including a .1 million contract with the Department of Homeland Security and FEMA that began in February 2023 and will conclude in August 2025. Tom Padgett, Smarsh’s president for enterprise business, stated that like Signal, messages sent through TeleMessage are encrypted, but the app does not address security issues raised by a recent incident involving Signal. The specifics of how government officials utilize TeleMessage remain unclear, and five cybersecurity experts admitted they were unfamiliar with the app prior to recent developments. TeleMessage licenses parts of its technology, including its encryption protocol, to other companies, but Signal clarified there is no formal agreement with TeleMessage and expressed concerns about the privacy and security of unofficial versions of their app.

5 steps I took for a successful in-place upgrade of my 6-year-old PC from Windows 10 to 11

Windows 11 was released in October 2021. A user upgraded from Windows 10 22H2 to Windows 11 24H2 on a six-year-old HP Omen using an in-place upgrade. They backed up important files using OneDrive, Proton Drive, and a 4 TB external drive. The hardware was checked for compatibility with Windows 11 using Microsoft’s support page and the PC Health Check app. The user decluttered the system using Disk Cleanup and Revo Uninstaller. A system restore point was created for safety before the upgrade. The upgrade was initiated through Settings -> Update & Security -> Windows Update or the Windows 11 Installation Assistant, and it proceeded smoothly, allowing the user to keep files and applications.
