Watch Out for This Info-Stealing Malware on Windows

A new malware strain called CoffeeLoader has been identified, posing a significant risk to gamers by masquerading as a legitimate ASUS utility, specifically the Armoury Crate software. Once it infiltrates a system, it deploys the Rhadamanthys infostealer, which can extract sensitive information such as credentials from web browsers, email clients, cryptocurrency wallets, and password managers. CoffeeLoader evades detection by most security tools by operating on the GPU instead of the CPU and using advanced techniques like call stack spoofing, sleep obfuscation, and exploiting Windows fibers. To protect against CoffeeLoader, users should exercise caution when downloading software, navigate directly to official websites, avoid suspicious links, and adhere to basic cybersecurity practices. If infection is suspected, users should disconnect from the internet, reboot in safe mode, delete temporary files, and check Task Manager for unusual activity. Employing a reliable malware scanner can help identify and eliminate infections.

Do Macs need antivirus? Debunking the security myth

Many users believe that Macs are immune to cybersecurity threats, leading them to neglect protective measures. This perception originated from Apple's marketing and the historical lower targeting of Macs due to their smaller market share. However, as the popularity of Macs has increased, so has the development of malware aimed at macOS. Reports indicate that malware targeting Macs has now outpaced that targeting Windows on a per-device basis. While macOS includes strong security features like XProtect, Gatekeeper, and System Integrity Protection, these are not foolproof. XProtect only defends against known malware, leaving users vulnerable to new threats. Macs are susceptible to various types of malware, including adware, Trojans, and phishing attacks. Antivirus software is important for Macs as it protects against evolving malware, shields users from phishing and online scams, enhances privacy protection, and prevents cross-platform threats.

Devious new Android malware uses a Microsoft tool to avoid being spotted

Cybercriminals are using legitimate software tools to create deceptive Android applications that steal sensitive user information. McAfee's findings indicate that hackers are exploiting the .NET MAUI framework to develop sophisticated malware that can evade traditional antivirus detection. The malware uses a multi-stage dynamic loading process, incrementally loading and decrypting code, making it difficult for security software to identify the applications' true nature. Hackers add extraneous settings and permissions to confuse security scanners and use encrypted communications for data transmission instead of standard internet requests. These malicious applications are not found in reputable app stores like Google Play but are distributed through unofficial app stores, often accessed via phishing links. Examples include a counterfeit banking app and a fraudulent social networking service targeting the Chinese-speaking community. The main goal of these apps is to secretly extract user data and send it to the attackers' servers. Users are advised to download apps only from official repositories and to be cautious by reviewing user feedback before installation.

How to Improve Game Data Loading Times in Windows

Most modern games rely on real-time asset loading, making storage choice crucial for optimal gaming. A slow SSD or HDD can lead to long loading times and performance issues. 1. Disabling NTFS Last Access Time can improve loading speeds by reducing disk overhead. This can be done via Command Prompt with the command: fsutil behavior set disablelastaccess 1. 2. Enabling Large System Cache can enhance performance for games with substantial assets, requiring at least 16 GB of RAM and editing the Windows Registry. 3. Disabling antivirus scanning for the game folder can reduce loading times by preventing real-time scans. This can be done through Windows Security settings. 4. Using an exFAT drive can efficiently process large files, which may benefit games with sizable assets. This involves creating a new volume in Disk Management. 5. Disabling Full-Screen Optimizations can reduce input lag and improve performance by changing settings in the game's executable properties. 6. Increasing Shader Cache Size can improve loading times, with Nvidia users advised to set it to 10 GB or Unlimited in the Nvidia Control Panel. 7. Using a third-party cache management program like PrimoCache can enhance loading times by reserving RAM for caching frequently used programs.

Do Macs Really Need Antivirus? The Truth About Mac Security in 2025

Mac users have historically believed their computers are immune to viruses and malware, but this notion may be outdated as cyber threats evolve. The rise in popularity of Macs has attracted cybercriminals, leading to the development of sophisticated malware and ransomware specifically targeting Mac operating systems. Phishing attacks have also become more prevalent, using impersonation tactics to extract sensitive information from users. Built-in security features like Gatekeeper and XProtect provide some protection, but experts now recommend considering third-party antivirus solutions for enhanced security, especially when handling private information, downloading from unverified sources, or using Macs in business environments. While some users worry that antivirus programs may slow down their systems, modern options are designed to be more efficient. Ultimately, the decision to use antivirus software depends on individual digital habits and risk tolerance.

How to Disable Antivirus on Your Computer

Antivirus software scans files for threats like viruses and malware and is generally recommended to be kept running continuously. However, it may need to be temporarily disabled in certain situations, such as to free up system resources, install a program that is being blocked, avoid false flags from the antivirus, or address privacy concerns. To disable antivirus on Windows 11, users can access Microsoft Defender through system settings and disable options like Real-time Protection and Tamper Protection. They may also need to disable the firewall if a download is blocked. On MacOS, the antivirus protection includes Gatekeeper, which cannot be disabled, and users can partially disable X-Protect but not Notarization. Before disabling antivirus, users should close non-essential programs, ensure they only download trusted files, and promptly re-enable the antivirus after completing necessary tasks. Disabling antivirus exposes the computer to potential malware threats, so caution is advised.

CCI Dismisses Antitrust Complaint Against Microsoft Over Windows Defender

The Competition Commission of India (CCI) investigated an antitrust complaint against Microsoft regarding its bundling of Microsoft Defender with the Windows operating system. The complaint, made by an anonymous informant, claimed that this practice hindered independent antivirus software developers. Key concerns included access to APIs, integration pathways, and default settings that limited third-party antivirus solutions. Microsoft defended its practices by stating that Defender is part of Windows at no extra cost and that users can install third-party antivirus programs, which can be set as the default. The CCI found no merit in the allegations, concluding there was insufficient evidence of anti-competitive behavior and that users have the freedom to choose their antivirus solutions.
