Windows 10 Support Ends Soon. Here Are Your Best Options if You Can’t Upgrade

Microsoft will end official support for Windows 10 on October 14, meaning users will no longer receive bug fixes, technical support, or security updates. Extended security updates (ESU) will be available for a fee, primarily aimed at businesses and educational institutions, with a consumer version available for one year. Users can also consider alternative operating systems like Linux or ChromeOS Flex. Microsoft suggests cloud solutions like Windows 365 or Azure Virtual Desktop for those unable to upgrade their devices. Some users are opting for third-party security software, such as the 0patch agent, to address security risks associated with using Windows 10 post-support. There are methods to bypass Windows 11 upgrade compatibility checks using tools like Rufus or Registry Editor modifications.

Inside Quick Heal’s Journey: Building India’s First Antivirus to a Global Brand

Quick Heal Technologies was founded by brothers Kailash and Sanjay Katkar in Pune, focusing on antivirus solutions to combat rising computer viruses. It became India's first homegrown antivirus and is now a globally recognized company. Despite India's digital economy expanding, only 7% of organizations are mature in cybersecurity readiness, facing challenges such as a skills deficit, fragmented security implementations, and a disconnect between executive priorities and security realities. India needs over 800,000 cybersecurity professionals, and educational institutions must integrate practical threat scenarios into their curricula. The "Make in India" movement is fostering indigenous cybersecurity solutions that address local threats while being globally relevant. Quick Heal utilizes AI to enhance threat detection and response, analyzing vast amounts of data while emphasizing the irreplaceable role of human expertise in strategic decision-making. Emerging threats include AI-powered social engineering, supply chain attacks, and cloud misconfigurations. Organizations should adopt Zero Trust architectures, invest in continuous security training, and utilize integrated threat intelligence. Quick Heal's leadership emphasizes solving real problems for customers and encourages young engineers to gain practical experience in cybersecurity. Recommended strategies for CISOs include aligning security investments with business priorities, embracing automation, and establishing integrated threat intelligence for effective risk management.

Beware of this Android antivirus. It actually steals data, records audio, and tracks you

LunaSpy is a deceptive antivirus application that spreads primarily through Telegram and is not available on the official Google Play Store. It masquerades as a legitimate antivirus program, claiming to protect online banking activities. Upon installation, it conducts a superficial scan and displays false warnings to instill fear, prompting users to grant extensive permissions. Once installed, it can invade personal data, access banking information, record audio and video, steal passwords, read SMS messages, track locations, and has been found to include a command for photo theft. Users are advised to avoid downloading LunaSpy and to exercise caution with applications from social networks or unofficial sources, relying instead on verified antivirus solutions from official app stores.

Your antivirus is under attack from new “killer” tool – here’s what we know

Cybercriminals are enhancing their capabilities to disable antivirus and endpoint detection and response (EDR) systems, with a new malware tool called EDRKillShifter being circulated in underground forums. This tool can neutralize EDR systems from vendors like Sophos, Bitdefender, and Kaspersky, using obfuscation techniques and signed drivers that may be stolen or compromised. EDRKillShifter was found embedded in the legitimate Clipboard Compare tool from Beyond Compare, indicating sophisticated tactics to evade detection. The malware emerged in mid-2024 after an unsuccessful attempt to disable antivirus software and deploy ransomware, revealing evolving strategies among attackers. To mitigate risks, Sophos recommends enabling tamper protection, maintaining robust security hygiene, and keeping systems updated, particularly regarding outdated signed drivers.

Understanding polymorphic malware: A comprehensive guide

Polymorphic malware is a type of malicious software that can change its code structure while maintaining its core functionality, making it difficult for traditional signature-based antivirus solutions to detect. It uses a mutation engine to create new variants by altering its code through techniques like code obfuscation, encryption, and junk code insertion. There are several categories of polymorphic malware, including polymorphic viruses, trojans, rootkits, and ransomware, each with unique characteristics. Detection of polymorphic malware is challenging due to its ability to evade conventional methods, prompting the use of behavioral analysis and machine learning for identification. To protect against such threats, a multi-layered security approach is recommended, including regular software updates, network segmentation, and employee training. Real-world examples like the Storm Worm and Conficker worm illustrate the significant impact of polymorphic malware, which has caused substantial financial losses. As cybersecurity measures advance, polymorphic malware continues to evolve, incorporating artificial intelligence and machine learning, leading to new challenges for security professionals. Cloud-based security solutions are emerging as effective tools to combat these threats.
