Another devious antivirus killer tool has been found – so make sure you’re protected

The Crypto24 ransomware group, identified in September 2024, employs advanced tactics to disable antivirus protections before launching attacks. They use a custom variant of the open-source tool RealBlindingEDR.malware to neutralize AV defenses, sometimes uninstalling antivirus programs entirely. After gaining access to a target system, they deploy a keylogger and an encryptor, exfiltrating data to Google Drive with a specialized tool. The group has targeted large organizations in the U.S., Europe, and Asia, focusing on sectors like finance, manufacturing, technology, and entertainment. Cybersecurity experts recommend a layered defense strategy, including reputable antivirus solutions with tamper protection, real-time monitoring, firewalls, and additional anti-malware tools to mitigate risks.

Make your Windows 11 taskbar transparent for a cool, minimalist vibe

Many users find the standard Windows 11 taskbar distracting and prefer a minimalist approach with a transparent taskbar. Windows 11 has a native transparency option under Settings > Personalization > Colors, but it typically results in a frosted glass effect. The TranslucentTB app, available for free on the Microsoft Store, allows users to customize the opacity and color of their taskbar. To use it, users should download and install the app, find the TranslucentTB icon in the System Tray, and select "clear" from the Visible Window menu for full transparency. Users can also adjust Security and Privacy settings if the app does not function properly. TranslucentTB offers dynamic behavior options, allowing the taskbar to change transparency based on user activity, such as becoming transparent only when a window is maximized.

Achieve up to 1.7 times higher write throughput and 1.38 times better price performance with Amazon Aurora PostgreSQL on AWS Graviton4-based R8g instances

Upgrading to Graviton4-based R8g instances with Aurora PostgreSQL-Compatible 17.4 in an Aurora I/O-Optimized cluster configuration results in significant performance improvements. The new instances provide up to 1.7 times higher write throughput, 1.38 times better price-performance, and reduce commit latency by up to 46% on r8g.16xlarge instances and 38% on r8g.2xlarge instances compared to Graviton2-based R6g instances. The Amazon Aurora PostgreSQL-Compatible Edition now supports AWS Graviton4-based R8g instances and PostgreSQL 17.4, which introduces performance enhancements for I/O-Optimized configurations, optimizing write operations and batch processing. R8g instances offer up to 192 vCPUs and 1.5 TB of memory, supporting larger configurations and providing up to 50 Gbps of network bandwidth. PostgreSQL 17 includes vacuum improvements, eliminates the need to drop logical replication slots during upgrades, and expands SQL/JSON standards. Aurora PostgreSQL-Compatible separates compute from storage, enabling independent scaling and maintaining six-way replication for durability, while processing changes as log records to reduce I/O operations. Performance benchmarks using HammerDB show improvements in throughput and commit latency across various workloads. For small workloads on 2xlarge instance size, throughput increased by 50.25% and commit latency improved by 33.87%. For medium workloads on 16xlarge instance size, throughput increased by 30% and commit latency improved by 17.44%. The most significant performance benefits arise from combining hardware upgrades from Graviton2 to Graviton4 with database engine upgrades from PostgreSQL 15.10 to 17.4. For small workloads, throughput increased by 70% and commit latency improved by 38.71%. For medium workloads, throughput increased by 70% and commit latency improved by 46.67%. Cost efficiency is also enhanced, with a 38% improvement in price performance and a 61.26% improvement in price-performance ratio when comparing Graviton2 and Graviton4 instances. Reserved Instances for Graviton4-based R8g instances offer additional cost-optimization opportunities.

Microsoft’s Edit on Windows is a new command line text editor

Microsoft introduced a new command-line text editor, Edit on Windows, during its Build conference. This open-source tool allows developers to edit files directly within the command prompt by typing “edit” and is designed to enhance the developer experience. Edit on Windows is less than 250KB in size and includes features such as key bindings for menu options, support for multiple files with ctrl + P shortcut, find and replace functionality with match case and regular expression support, and word wrapping capabilities. The motivation for creating Edit was to provide a default CLI text editor for 64-bit versions of Windows, which previously lacked an integrated command-line editor. Edit on Windows will be available through the Windows Insider program in the upcoming months. Additionally, Microsoft is rebranding Windows Dev Home to Advanced Windows Settings, which will simplify customization for developers and integrate additional features into the main Windows 11 settings interface.
