You Can Use A GameCube Controller On Your PC – Here’s How

Many leading gaming brands are now offering USB-cable versions of controllers for better compatibility. Nintendo's Switch 2 features a controller that connects to Windows systems via cable or Bluetooth with a dedicated PC application. The original GameCube controller requires an external adapter for PC use, as it lacks a USB connection. To use a GameCube controller on a PC, an adapter is necessary, with popular options including the official Wii U adapter and various Mayflash models. The adapter must be set to the correct mode for the games being played, particularly for emulated GameCube titles. As of late 2025, Steam supports GameCube controllers natively, including rumble support, and recognizes both original controllers with adapters and third-party alternatives. The GameCube controller designed for the Switch 2 is also compatible with Steam. Users should ensure their Steam client is updated and can customize controls using Steam Input. While the GameCube controller is effective for games designed for it, it may not perform optimally for modern games.

Windows Defender ‘BlueHammer’ vulnerability now exploited as part of malware campaigns — CISA issues warning despite patch release on April 14

A race condition vulnerability in Windows Defender, known as BlueHammer, has been exploited by the hacker Nightmare Eclipse, allowing attackers to gain SYSTEM user access. Microsoft released a patch for this vulnerability on April 14, but the Cybersecurity and Infrastructure Security Agency (CISA) has flagged it as actively exploited in ransomware campaigns. The average time to apply critical OS patches across Windows 10 and 11 is now 127 days, with enterprise environments averaging 76 days. Estimates suggest that 15% to 26% of Windows 10 machines remain unpatched, with a conservative estimate of 20% translating to one in five machines being vulnerable. Microsoft has extended security updates for Windows 10 until October 14, 2027, but public awareness of the updates remains low.

New Millenium RAT version infects 62,000 Windows systems worldwide

A significant evolution of the Millenium remote access trojan (RAT) has impacted over 62,000 Windows devices across more than 160 countries. The latest version, 4.*, marks a departure from previous .NET-based versions and is attributed to a threat cluster known as Y2K Operators, with the creator identified as “ShinyEnigma.” There are 62,289 infected endpoints, with 39,730 infections occurring in the first quarter of 2026. The RAT is marketed as malware-as-a-service (MaaS) and promoted through underground forums and platforms like GitHub, with accessible pricing. Millenium RAT 4 is developed in native C++ and uses the Telegram Bot API for command-and-control communications. Its capabilities include stealing browser data, collecting system information, logging keystrokes, capturing screenshots and audio, accessing Telegram and Discord data, downloading additional payloads, and executing Windows or PowerShell commands. The malware ensures persistence by replicating itself in the %APPDATA% directory and creating an autorun registry entry. The malware is distributed through social engineering tactics such as cracked software, cryptocurrency utilities, hacking toolkits, OSINT tools, exploit builders, and Roblox-related cheats. Some campaigns have trojanized malware builders, infecting cybercriminals. One campaign used PDF-themed lures with a malicious Windows shortcut to download the RAT while displaying a legitimate document. Payloads often use filenames associated with Windows components or security software to blend into infected systems. Group-IB recommends avoiding untrusted executables, applying security updates, enabling multi-factor authentication, and monitoring for unusual autorun registry entries.

Windows RAT Uses Encrypted HTTP C2 and Registry Persistence After npm Infection

A malware campaign targets Windows systems through a malicious npm package named postcss-minify-selector-parser, which mimics the legitimate postcss-selector-parser. This counterfeit package installs a Remote Access Trojan (RAT) on developer machines, beginning with a multi-stage attack triggered by the installation of the package. The RAT can steal credentials, execute shell commands, and communicate with a remote attacker. Security researchers at JFrog identified this threat and reported it on June 22, 2026, noting that two additional related packages, postcss-minify-selector and aes-decode-runner-pro, are linked to the same publisher and remain live on the npm registry. The RAT employs encrypted HTTP communication with a command-and-control (C2) server and ensures persistence by creating a registry key under the Windows Run key. It has capabilities for remote shell execution, file uploads and downloads, and can steal saved login data from Google Chrome using Windows decryption APIs. The malware is designed for organized batch exfiltration of stolen data. Indicators of compromise include specific IP addresses, domains, file paths, and SHA-256 hashes associated with the malware components. JFrog advises users to remove the malicious packages, inspect their dependency trees, and treat any stored credentials as compromised.

Microsoft and Adobe team up and make Photoshop 20% faster on Windows

Microsoft is collaborating with Adobe to enhance the performance of Photoshop, a widely used image editing software. The partnership focuses on optimizing operations within Photoshop, which is primarily developed in C++ and compiled using Microsoft’s Visual C++ (MSVC) compiler. Microsoft aims to improve performance for CPU-intensive tasks, particularly those that are latency-sensitive, such as brush responsiveness and file-opening tasks. The engineering team activated MSVC’s "peak-performance" compilation mode and explored profile-guided optimization (PGO) to refine executables. However, due to the complexity PGO introduced, they shifted to Sample-based Profile Guided Optimizations (SPGO), which uses hardware performance samples from actual release binaries. This method allows for greater flexibility in data collection and typically yields performance improvements of 5% to 15%. By combining MSVC’s peak-performance mode with SPGO, the teams achieved a 20% performance boost on x64 Windows systems and a 13% enhancement on Arm architecture. These optimizations resulted in improved responsiveness for critical tasks in Photoshop, enhancing the user experience in professional creative workflows.

Windows SprySOCKS Malware: Advanced Kernel-Level Rootkit Targets Government Organizations via Supply Chain Vulnerabilities

The Windows variant of SprySOCKS malware, developed by the Chinese threat group Earth Lusca, targets government entities globally and features advanced capabilities such as rootkit-level stealth and extensive command-and-control (C2) functionalities. It operates on Windows systems, utilizing two main variants: WINDRV, which includes kernel drivers for stealth operations, and WINPLUS, a streamlined backdoor. The malware can communicate over TCP, UDP, and WebSocket, offering over 30 C2 commands for various operations, including system information gathering and keystroke logging. WINDRV loads a driver named ‘RawWNPF’ into memory using another signed kernel driver, allowing it to conceal processes and achieve persistence. The malware's design incorporates open-source elements and exploits vulnerabilities in the software supply chain, notably using a leaked certificate for driver signing. To combat SprySOCKS, organizations are advised to implement advanced endpoint detection and response (EDR) solutions, maintain regular patching, and manage supply chain risks vigilantly. The malware's adaptability and reliance on legitimate certificates complicate detection efforts, necessitating continuous refinement of security practices.
