Android users need to uninstall these apps ASAP as they are a security risk

Google will soon notify Android users when an app they installed has lost developer support. Currently, users only receive alerts from Play Protect for significant security threats or potentially harmful apps. The only way to discover if an app has been delisted is through external sources or by trying to install it on a new device. Recent findings in the Play Store indicate that Google is preparing to inform users when apps have been removed from the Play Store and will no longer receive updates. Abandoned apps pose significant security risks, as they may contain vulnerabilities that can be exploited by malicious actors. Google's new notifications aim to encourage users to uninstall unsupported apps to protect their personal data.

New Windows Zero-Day Exploit ‘RoguePlanet’ Released

A new zero-day exploit named RoguePlanet has been discovered targeting Microsoft’s Windows operating system, disclosed by security researcher Nightmare Eclipse. The exploit allows local privilege escalation (LPE) by exploiting a race condition in Microsoft Defender and can facilitate remote code execution (RCE) through deceptive .vhd(x) files. RoguePlanet may also bypass BitLocker encryption. The proof-of-concept has been tested on Windows 10 and Windows 11 systems but does not function on Windows Server, although the researcher believes all Windows Server versions are vulnerable. Following its release, RoguePlanet was confirmed by other researchers to spawn a command prompt with SYSTEM privileges on patched computers. This disclosure comes after Microsoft released patches for earlier exploits by Nightmare Eclipse, including GreenPlasma and YellowKey. The researcher has expressed dissatisfaction with Microsoft’s vulnerability disclosure process, alleging legal action against them and the suspension of their GitHub account, leading to the publication of RoguePlanet under a new account.

Exclusive: How One Line of Code Put Billions of Microsoft Android App Downloads at Risk

A significant security vulnerability has been found in six Microsoft 365 Android applications, including Word, PowerPoint, Excel, Microsoft 365 Copilot, Microsoft Loop, and OneNote, due to an active debug flag left in the production code. This oversight allowed untrusted apps to request and receive access tokens, compromising user account security. An attacker could exploit this vulnerability by embedding malicious code in a widely distributed app, enabling unauthorized access to sensitive information such as emails, documents, and communications. Microsoft confirmed the issues and issued CVE numbers CVE-2026-41100, -41101, and -41102, releasing patches through their Patch Tuesday mechanism and a specific patched build on the Google Play Store. Users are advised to update their applications to mitigate the risk.

Windows 11 sandbox flaw lets attackers escape with one click

SafeBreach Labs identified a vulnerability in Windows 11, named Click Or Trick, cataloged as CVE-2025-59199, which was addressed by Microsoft in October 2025. The vulnerability allows a one-click attack from a low-integrity process to achieve arbitrary write capabilities and escalated code execution by exploiting built-in Windows components. The researchers discovered a COM object with an undocumented flag that enabled a low-integrity process to launch a medium-integrity server process using the user's logon token. They found that certain applications could accept command-line parameters through notifications, allowing attackers to execute commands. The Snipping Tool was leveraged to transition execution to another registered application, such as Microsoft Teams, enabling the injection of a remote debugging switch. This exploit chain involved multiple Windows subsystems and was assigned a CVSS score of 7.8.

Windows Server 2016 Update: Disastrous Bug Breaks AD

Microsoft released a mandatory patch (KB5087537) for Windows Server 2016 to enhance cryptographic layers and address critical vulnerabilities. This update is essential for organizations using legacy workloads, as mainstream support ended in January 2022, but extended support continues until January 12, 2027. The patch aims to prepare systems for the expiration of Windows Secure Boot certificates in June 2026, which, if not updated, could compromise security and expose systems to malware. The update uses a phased deployment model and includes a new SecureBoot folder to assist IT professionals in managing certificate status. It also addresses various quality-of-life issues, including bugs affecting Remote Desktop Connection and authentication errors with Microsoft services. However, a significant issue arises when the host server name is exactly 15 characters long, causing failures in the domain controller discovery process and obstructing critical operations. This bug is linked to the historical 15-character limit of NetBIOS, which affects the Active Directory lookup mechanism. Microsoft has acknowledged the issue but has not provided a timeline for a fix, leaving administrators to either rename servers or uninstall the update. As the Secure Boot deadline approaches, IT departments must carefully assess their environments to avoid disruptions while ensuring security compliance.

FAQ: What you need to know about expiring Windows Secure Boot certificates

Secure Boot is a security mechanism that authenticates firmware-based software through trusted certificates during the startup process of Windows, preventing unauthorized code execution. It is part of the UEFI firmware standard and was introduced in 2011 to allow only verified, signed code to run at startup. Microsoft first implemented Secure Boot certificates in 2011 as an optional feature in Windows 8, and it remained optional in Windows 10. However, it became a mandatory requirement with the launch of Windows 11 in 2021, indicating the widespread adoption of UEFI systems.
