Do I need an antivirus and a VPN?

Reliance on antivirus software for device protection is common, but certain threats, especially ransomware, can bypass even the best solutions. Cybercriminals have shifted tactics from encrypting data for ransom to exfiltrating sensitive information and threatening to leak it. The availability of ransomware kits and the use of AI by attackers have made cybercrime more accessible and targeted. Remote work environments increase vulnerabilities, as hackers exploit unsecured networks and personal devices. Antivirus software can help protect against malware and viruses, but built-in solutions often lack comprehensive security. A high-quality antivirus program can enhance protection through advanced features and AI. A Virtual Private Network (VPN) encrypts data and secures internet traffic, making it a valuable tool for cybersecurity. Implementing a VPN is cost-effective compared to potential data breach costs. Using both a VPN and antivirus software is essential for comprehensive coverage, as they address different security aspects. Businesses may need advanced endpoint protection solutions for heightened security, which continuously scans for suspicious behavior and integrates multiple security features. Despite these tools, proper personal practices and cybersecurity awareness are crucial to minimize vulnerabilities and human error, which is a leading cause of cyberattacks.

Windows 11 is getting top-level protection against the next generation of quantum cyberattacks

Microsoft has announced new protective measures against potential quantum-powered cyber threats by rolling out post-quantum cryptography (PQC) capabilities for Windows Insiders using Canary Channel Build 27852 and higher, and for Linux users through SymCrypt-OpenSSL version 1.9.0. The newly introduced PQC algorithms, standardized by NIST, will evolve in response to emerging threats, emphasizing the need for "Crypto Agility." The updates enhance OpenSSL’s API surface for Linux developers, allowing experimentation with TLS hybrid key exchange. Experts warn that quantum computing could breach even the most robust encryption systems, highlighting the urgency for software companies to adapt their security measures.

This Stealthy Malware Takes Control of Your Computer to Steal Your Data

Skitnet is a new malware that targets personal data by stealthily infiltrating computer systems. It is used by hackers to steal sensitive information through advanced methods, including the insertion of invisible malicious code in emails and the creation of fraudulent websites. Cybersecurity experts from PRODAFT have revealed that Skitnet is often employed by ransomware groups and can remotely control infected computers using services like AnyDesk. The malware operates discreetly, monitoring user actions without detection for extended periods, making it difficult for victims to realize they are infected until after data theft occurs. To protect against such threats, security specialists recommend identifying suspicious emails, using reliable antivirus software, and enhancing account security with two-step verification and strong passwords.

Microsoft Tells Nearly All Windows Users—You Must Reboot Your PC

This month's KB5058497 update for Windows 11 24H2 introduces the first 'hotpatch' update, allowing installation without a reboot, but it is only available for Windows 11 24H2 Enterprise users. There is no timeline for extending this feature to Pro and Home users. To use hotpatch updates, users must have a Microsoft subscription that includes Windows 11 Enterprise E3, E5, or F3, Windows 11 Education A3 or A5, or a Windows 365 Enterprise subscription, along with devices running Windows 11 Enterprise version 24H2 (Build 26100.2033 or later), an x64 CPU, Microsoft Intune for deployment management, and Virtualization-based Security (VBS) enabled. Users of Windows 11 24H2 or older versions must reboot their systems to apply new security updates, except for specific patches for Windows Defender, while every third update will still require a reboot. KB5058497 is scheduled to be released between May and June 2025 during the 'no restart' period, and it has been reported to install seamlessly without prompting for a reboot. Users of Windows 11 Home and Pro still face the traditional monthly reboot requirement for updates.

Microsoft says Lumma password stealer malware found on 394,000 Windows PCs

Microsoft, in collaboration with law enforcement, has taken legal action against the Lumma malware operation, which has affected over 394,000 Windows PCs globally, particularly in Brazil, Europe, and the United States. A federal court authorized the seizure of 2,300 domains used as command and control servers for Lumma, and the Justice Department confiscated five additional domains related to its infrastructure. Lumma is primarily spread through questionable games or cracked applications and extracts sensitive information such as logins, passwords, credit card details, and cryptocurrency wallets, which is then sold to other cybercriminals. Lumma also facilitates the deployment of additional malware, including ransomware, and has been linked to significant cyberattacks on major tech companies like PowerSchool and Snowflake, resulting in substantial data theft.

Microsoft says 394,000 Windows computers infected by Lumma malware

Microsoft announced the dismantling of the Lumma Stealer malware project in collaboration with global law enforcement. Over 394,000 Windows computers were identified as infected by Lumma between March 16 and May 16. The malware is known for stealing sensitive information such as passwords and credit card details. Microsoft, with a court order, dismantled the web domains supporting Lumma's infrastructure, while the U.S. Department of Justice took control of its central command structure. More than 1,300 domains were seized or transferred to Microsoft, with 300 acted upon by law enforcement and Europol. Other tech firms like Cloudflare and Lumen assisted in this effort. Since 2022, hackers have been acquiring Lumma through underground forums, and it has been used in phishing campaigns and attacks on various sectors, including gaming, education, and critical infrastructure.

Mac users once skipped antivirus software — here’s why that’s no longer a good idea

In 2024, 22 new Mac malware families emerged, up from 13 in 2022, indicating a rise in malware targeting macOS. Built-in security features include XProtect, which warns users about known malicious software; Gatekeeper, which prevents the installation of unsigned software; Sandboxing, which isolates applications to prevent unauthorized changes; Lockdown Mode, which restricts app functionality to protect user data; Safari protections against phishing and tracking; and password security measures that alert users about weak or compromised passwords. While Apple's built-in protections are robust, third-party antivirus software may provide additional security layers. Users are advised to practice good security habits, keep software updated, avoid unverified apps, and use a VPN on public Wi-Fi.
