5 reasons why Windows isn’t the best OS for productivity

Operating systems significantly influence user interactions with computers, accommodating various preferences. Windows is the most widely used operating system for traditional desktops but has several productivity limitations: 1. Windows installations often come with excessive pre-installed applications (bloatware), unlike macOS and most Linux distributions, which have minimal bloatware. 2. Windows lacks built-in productivity software, requiring users to purchase Microsoft Office or use alternatives, while macOS includes basic applications and Linux offers LibreOffice for free. 3. Windows does not have an integrated local file-sharing solution comparable to Apple's AirDrop, making file transfers between devices more cumbersome. 4. Keyboard and touchpad shortcuts in Windows are less intuitive and consistent compared to macOS, which can hinder productivity for users accustomed to macOS gestures. 5. Windows is a primary target for malware due to its widespread use, leading to a higher risk of system compromise compared to macOS and Linux, which encounter less malware.

New HeartCrypt Packer-as-a-Service (PaaS) Protecting Malware From Antivirus

HeartCrypt is a packer-as-a-service (PaaS) developed in July 2023 and launched in February 2024, designed to help malware operators evade antivirus detection. It has facilitated the packing of over 2,000 malicious payloads across 45 malware families. HeartCrypt injects harmful code into legitimate executable files, complicating detection by antivirus software. It is promoted on underground forums and Telegram channels, charging a fee per file for packing Windows x86 and .NET payloads. Its clients include operators of malware families like LummaStealer, Remcos, and Rhadamanthys. The packing process involves several techniques: - Payload Execution: The payload is encrypted with a single-byte XOR operation and executed through process hollowing or .NET framework capabilities. - Stub Creation: Position-independent code (PIC) is integrated into the binary’s .text section. - Control Flow Hijacking: The entry point of the original binary is altered to redirect execution to the malicious PIC. - Resource Addition: Resources disguised as BMP files contain encoded malicious code. - Obfuscation Techniques: Multiple layers of encoding are used, including stack strings and dynamic API resolution. HeartCrypt employs anti-analysis techniques such as loading non-existent DLLs to detect sandbox environments and using virtual DLLs to evade Windows Defender’s emulator. The service lowers entry barriers for malware operators, potentially increasing malware infections. Security researchers have analyzed HeartCrypt payloads, revealing insights into its operations and associated malware campaigns.

Microsoft Defender Is Not Enough Anymore—This Malware Gets Around It

A victim lost over ,000 in cryptocurrency due to a malware attack that bypassed Microsoft Defender. The attacker persuaded the victim to download a malicious application disguised as a game called Orbit Unit via Telegram. The malware accessed the victim's Google passwords through an unlocked Bitwarden, compromising his cryptocurrency wallet. Despite having Malwarebytes installed, it did not provide real-time protection, only identifying the malware after the damage was done. Researchers confirmed that Microsoft Defender failed to block the malware or detect it once operational. The malware used PowerShell to execute scripts and installed a deceptive Chrome extension to steal credentials and manipulate browser activity. In tests, Malwarebytes with real-time protection blocked the malware, while Bitdefender prevented access to sensitive information. The malware did not execute if the user was located in Russia, Ukraine, or Belarus. SafetyDetectives advised against storing wallet passwords digitally and recommended using reputable antivirus software with real-time protection. They also suggested limiting cryptocurrency in browser wallets and using hardware wallets for significant amounts.

Best Anti-Malware Software for Mac 2025

Cyber threats are increasingly targeting macOS, making it essential for Mac users to invest in dedicated anti-malware and antivirus software in 2025. Anti-malware software detects, prevents, and eliminates a broader range of threats, including spyware, adware, ransomware, and trojans, while antivirus software primarily focuses on viruses. Both types of software aim to protect devices from harmful threats but operate differently. Antivirus software relies on signature-based detection, which may not be effective against newer threats, whereas anti-malware software uses heuristic and behavioral analyses for broader protection.
