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.

Fake Antivirus App Spreads Android Malware to Spy on Russian Users

Cybersecurity experts at Doctor Web have identified a new variant of Android malware called Android.Backdoor.916.origin, active since January 2025. This malware can eavesdrop on conversations, steal messages, stream video, and log keystrokes. It targets Russian business representatives rather than average users, being distributed through direct messages as a fake antivirus app named GuardCB, which mimics the Russian Central Bank's emblem. The app requests extensive permissions, including geolocation, audio recording, camera access, and SMS data, and can function as a keylogger. It is designed for persistence, launching background services and communicating with multiple command-and-control servers. The malware can livestream audio, broadcast video, capture text, and upload contacts and call history. It exploits Android’s Accessibility Service to capture keystrokes and prevent uninstallation. The interface is exclusively in Russian, indicating it is specifically designed for a targeted group. Users in Russia are advised to download applications only from trusted sources to mitigate risks.

Everyting About Postgres Security

Securing a PostgreSQL database involves following the Center for Internet Security (CIS) benchmarks, which include: 1. Installation and Patches: - Ensure PostgreSQL packages are obtained from authorized repositories, specifically the PostgreSQL Global Development Group (PGDG). - Enable systemd service files for managing PostgreSQL services. - Confirm that the data directory (PGDATA) is initialized properly. 2. Directory and File Permissions: - Set the correct file permissions mask to prevent unauthorized access. 3. Logging and Auditing: - Implement logging for monitoring and auditing purposes. 4. User Access and Authorization: - Review and configure sudo permissions to limit administrative access. 5. Connection and Login: - Avoid specifying passwords in the command line to prevent exposure in shell history or process lists. 6. PostgreSQL Settings: - Understand potential attack vectors and configure runtime parameters accordingly. 7. Replication: - Create a dedicated replication user with limited permissions. 8. Special Configuration Considerations: - Place PostgreSQL subdirectory locations outside the main data directory for enhanced security and manageability.

Windows 11 insider builds have new File Explorer dark mode

Users of Windows 11 have experienced inconsistencies with dark mode, as some dialog boxes remain white despite the overall dark theme. A new beta feature in Windows 11 Insider Beta and Dev builds allows File Explorer dialog boxes to adopt a dark mode appearance, which was previously unavailable. This feature can be accessed by users on specific Insider builds (26120.5751 for Beta or 26200.5751 for Dev) released on August 15, 2025. To enable the dark mode dialog boxes, users must use ViveTool, a utility that unlocks hidden features, and execute specific commands after installing the Insider build. Although the dark mode dialog boxes are now available, some buttons within them may still appear in gray, indicating that Microsoft is still refining this aspect of the user interface. Other windows, such as the Run dialog box and Control Panel, still show inconsistencies in color schemes.

Threat Actors Abuse Microsoft Help Index File to Execute PipeMagic Malware

Cybersecurity researchers have identified a malware campaign that uses Microsoft Help Index Files (.mshi) to deploy the PipeMagic backdoor, which has primarily targeted organizations in Saudi Arabia and Brazil in 2025. PipeMagic first appeared in December 2022 during a RansomExx ransomware campaign and exploits CVE-2025-29824, a vulnerability recognized by Microsoft as actively exploited. The malware has evolved from exploiting CVE-2017-0144 to using advanced social engineering techniques. The latest campaign employs .mshi files containing obfuscated C# code and encrypted payloads, utilizing the MSBuild framework for execution to bypass security controls. The infection process begins with executing a malicious metafile.mshi, which decrypts shellcode using an RC4 stream cipher and executes it via the Windows API function EnumDeviceMonitor. The decrypted shellcode is designed for 32-bit Windows systems and uses evasion techniques to complicate analysis, ultimately establishing the PipeMagic backdoor on the system and enabling communication through a named pipe at 127.0.0.1:8082.
