Google's AI security agent, Big Sleep, has identified a vulnerability in SQLite, designated as CVE-2025-6965, which was being exploited by hackers. Enhancements have been made to Google's open-source forensics tool, now operating on the upgraded Sec-Gemini platform for improved log analysis and threat detection. Google is set to unveil FACADE, an insider threat detection system that has monitored billions of daily events since 2018 using contrastive learning. At DEF CON 33, Google will co-host a Capture the Flag event with Airbus, involving AI assistants in security challenges. Google is contributing data from its Secure AI Framework to the Coalition for Secure AI to enhance research in cybersecurity. The AI Cyber Challenge, a DARPA-led competition supported by Google, is nearing its conclusion, with winners showcasing AI tools for identifying and rectifying vulnerabilities in open-source software.

Microsoft is phasing out JScript in Windows 11 24H2 in favor of JScript9Legacy to enhance security. JScript9Legacy is enabled by default and will manage all scripting processes previously reliant on JScript without requiring user action. This new scripting engine offers improved performance, compatibility with modern web standards, and advanced security features to mitigate risks such as cross-site scripting (XSS). The transition is designed to be seamless, although Microsoft has not provided procedures for reverting to JScript if compatibility issues arise. The change is limited to Windows 11 24H2, with no updates planned for earlier Windows versions.

Microsoft is preparing to initiate a private preview of new Windows changes aimed at relocating antivirus (AV) and endpoint detection and response (EDR) applications away from the Windows kernel. This initiative follows a significant incident involving a faulty update from CrowdStrike that disrupted 8.5 million Windows-based machines globally. Microsoft is collaborating with industry leaders such as CrowdStrike, Bitdefender, ESET, and Trend Micro to develop a new endpoint security platform. The company is engaging its top engineers, including original architects of Windows, to work on these security enhancements. The upcoming private preview will allow security vendors to suggest modifications, with several iterations anticipated before the final version is ready. Microsoft is also addressing concerns related to kernel-level drivers in anti-cheating engines for gaming and is engaging with game developers on minimizing kernel usage. A forthcoming Windows update will introduce a Quick Machine Recovery feature to expedite restoration of machines encountering boot issues. Additionally, Microsoft is redesigning the Blue Screen of Death (BSOD) from blue to black as part of its commitment to enhancing user experience and system reliability.

Windows users are facing security challenges, including zero-day vulnerabilities and hackers bypassing Windows Defender. Microsoft has removed VPN provisions for Windows Defender and discontinued security support for Windows 10, but users can upgrade to Windows 11 for free. Following the April 8 Patch Tuesday updates, a new folder named "inetpub" appeared on user devices, which Microsoft has warned users not to delete, as it is essential for security protections. This folder is generated after installing updates and is traditionally associated with the Internet Information Services (IIS) web server platform, regardless of whether IIS is installed. If users have deleted the inetpub folder, it can be restored by enabling IIS through the Windows Control Panel.

Former National Security Adviser Mike Waltz has come under scrutiny for using TeleMessage, an app that has recently experienced a security breach resulting in the theft of sensitive data, including direct messages and group chats. High-ranking officials from the Trump administration, including Waltz, Vice President J.D. Vance, Secretary of State Marco Rubio, and Director of National Intelligence Tulsi Gabbard, were reported to have used the app. A photograph captured Waltz during a Cabinet meeting appearing to use TeleMessage to access Signal messages, raising concerns due to his previous controversy involving a chat room on Signal that included a journalist. The security vulnerabilities of TeleMessage have been criticized, particularly as it lacks the robust encryption features of Signal. The app was initially marketed as a solution for preserving messages for government record-keeping, but its reliability has been questioned.

A significant vulnerability, designated as CVE-2025-3500, has been identified in Avast Free Antivirus, allowing attackers to gain elevated system privileges and execute malicious code at the kernel level. The vulnerability has a high CVSS score of 8.8 and was publicly disclosed on April 24, 2025, shortly after a patch was implemented. It originates from inadequate validation of user-supplied data in the aswbidsdriver kernel driver, leading to an integer overflow prior to buffer allocation. Attackers must first execute low-privileged code on the target system to exploit this vulnerability. The flaw affects multiple versions of Avast Free Antivirus, specifically versions ranging from 20.1.2397 to 2016.11.1.2262. A fix was released in version 25.3.9983.922, and users are urged to update their software promptly. Security experts recommend enabling automatic updates and using standard user accounts for daily activities to mitigate risks.

Microsoft's recent security update for Windows has raised concerns among users due to the introduction of a new vulnerability. The update, intended to address the CVE-2025-21204 vulnerability, inadvertently created a folder named inetpub, which Microsoft claims is essential for user protection. Security researcher Kevin Beaumont has warned that this update has introduced a denial of service vulnerability that allows non-admin users to halt future Windows security updates. Microsoft has classified the issue as moderate in severity and suggested that deleting the inetpub symlink and retrying the update may resolve the problem. The report has been forwarded to the Windows security team for potential further action.

Microsoft's recent patch for CVE-2025-21204 inadvertently reintroduced the inetpub folder at c:inetpub as part of its mitigation strategy, raising concerns among system administrators. Security researcher Kevin Beaumont discovered that this folder created a new vulnerability when he used the mklink command with the /j parameter to redirect the folder to a system executable (notepad.exe). This allowed standard users to prevent Windows updates without administrative rights, as the command could be executed on default-configured systems. Beaumont has notified Microsoft of this vulnerability, but the company has not yet responded.

Windows users are facing security challenges, including a zero-day vulnerability that threatens Windows passwords and hackers bypassing Windows Defender. Microsoft has discontinued VPN support for Windows Defender users and withdrawn security support for Windows 10. A new folder named "inetpub" was created following the April 8 Patch Tuesday updates as part of the fix for CVE-2025-21204, a vulnerability in the Windows Update Stack. This folder has raised concerns among users, prompting Microsoft to advise against deleting it. The creation of the inetpub folder is intended to enhance security, although its purpose remains unclear. Microsoft confirmed that the folder is created regardless of whether Internet Information Services (IIS) is installed on the user's device.

A critical remote code execution vulnerability, designated as CVE-2024-43639, has been identified in Microsoft’s Windows Key Distribution Center (KDC) Proxy. This flaw arises from an integer overflow due to a missing validation check for Kerberos response lengths, allowing unauthenticated remote attackers to execute arbitrary code with the privileges of the target service. The vulnerability specifically affects KDC Proxy servers and was addressed in a November 2024 security update by implementing necessary length validation checks. Organizations using remote authentication services reliant on the KDC Proxy, such as RDP Gateway or DirectAccess, are particularly at risk. Immediate patching is advised, and monitoring for potential exploitation attempts is recommended.
