Windows zero-days expose gaps in built-in security protections

Two Windows zero-day vulnerabilities, YellowKey and GreenPlasma, have been identified. YellowKey targets the Windows Recovery Environment (WinRE) on Windows 11 and Windows Server 2025, allowing attackers with physical access to bypass BitLocker protections using a USB device. GreenPlasma affects Windows 10, Windows 11, and Windows Server environments with active Collaborative Translation Framework Monitor (CTFMON) sessions, enabling local privilege escalation from a standard user account to SYSTEM-level privileges. Both vulnerabilities require either physical or local access to exploit. Microsoft has not yet released patches for these vulnerabilities, prompting organizations to enhance their security measures and operational resilience. Recommendations include reassessing physical security, limiting local administrative access, and implementing multifactor authentication and robust credential management practices.

Microsoft Defender Zero-Day Vulnerabilities RedSun and UnDefend Actively Exploited on Windows 10, 11, and Server (April 2026 CVE Analysis)

In April 2026, two zero-day vulnerabilities, RedSun and UnDefend, were discovered in Microsoft Defender, affecting Windows 10, Windows 11, and Windows Server platforms. These vulnerabilities allow attackers to escalate privileges to SYSTEM and bypass Defender’s protections. RedSun exploits a flaw in Defender's remediation process, enabling low-privileged users to overwrite critical system files. UnDefend allows attackers to disrupt Defender’s updates, keeping it outdated and ineffective. Both vulnerabilities are actively being exploited, with attackers leveraging them to gain persistent access and deploy ransomware. The primary targets are organizations using Windows systems with Defender enabled, particularly in sectors like finance, healthcare, and government. Mitigation strategies include applying updates for related vulnerabilities, monitoring for suspicious activities, and implementing additional security measures.

Do you need antivirus on your phone?

Mobile security discussions often question the necessity of antivirus programs for smartphones. While traditionally seen as essential, the need for antivirus software is being reevaluated, especially for advanced smartphones. Apple's iPhone has stringent security measures that prevent traditional antivirus scanning, with scams being the primary threat rather than viruses. In contrast, Android devices allow sideloading, increasing the risk of malware, despite Google monitoring the Play Store. For users primarily downloading from official stores, antivirus applications may not be necessary. Instead, users should focus on keeping devices updated, using strong passwords, and enabling two-factor authentication to enhance security.

What the Tech: Antivirus Software for Smartphone

Many users believe that smartphones need antivirus software, similar to computers. However, most users can navigate their mobile experience without it due to built-in security features in operating systems like iOS and Android, which include regular updates, app store security, and user awareness. Antivirus apps may be necessary for users who download apps from third-party sources or engage in risky online behavior. The decision to install antivirus software should depend on individual usage patterns and risk tolerance.

Google’s AI Studio enables rapid Android app creation in minutes

Google has introduced enhanced web-based AI tools in its AI Studio platform, allowing users to generate complete native Android applications from natural-language prompts. This process enables individuals without programming skills to create installable APKs in minutes. The Build mode accepts plain-English descriptions to construct comprehensive native Android projects, which can then be customized in Android Studio. The tools support integration with third-party APIs and Web3 SDKs, allowing AI-generated apps to interact with blockchain functionalities. This development offers opportunities for the cryptocurrency sector, enabling decentralized finance protocols or wallet providers to create lightweight companion apps without extensive engineering teams. The integration with the Android ecosystem positions Google to reshape competitive dynamics in mobile app development. However, there are security concerns regarding the AI-generated code, particularly related to vulnerabilities in rapidly generated mobile apps that interact with smart contracts.

20-Year-Old PostgreSQL Flaw Gets Public PoC Exploit for Remote Code Execution

A proof-of-concept exploit for CVE-2026-2005 has been released, highlighting a significant vulnerability in the PostgreSQL pgcrypto extension that allows for remote code execution (RCE). This flaw, rooted in legacy code for nearly 20 years, enables attackers to escalate privileges and execute arbitrary commands on compromised servers. The vulnerability is found in the PGP session key parsing logic of the pgcrypto module and involves a heap-based buffer overflow, granting attackers arbitrary read and write access to memory. The exploit, shared by researcher “var77” on GitHub, demonstrates a multi-stage process that bypasses modern security measures like Address Space Layout Randomization (ASLR) using specially crafted PGP messages. The attack involves several steps, including heap pointer leakage, arbitrary memory read, identification of executable memory regions, and privilege escalation to the PostgreSQL superuser level, ultimately allowing the execution of OS-level commands. The vulnerability affects PostgreSQL deployments with the pgcrypto extension enabled, particularly those using vulnerable code versions. Successful exploitation can lead to full database compromise, unauthorized data access or modification, and potential lateral movement within networks. Organizations are advised to update PostgreSQL, restrict pgcrypto usage, limit user privileges, and monitor for unusual activity to mitigate risks.
