Microsoft no longer claims that Windows 11 has all the protection that you need

In April, Microsoft published a blog post discussing the security features of Windows 11, emphasizing that its built-in protections, such as Microsoft Defender Antivirus and SmartScreen, may eliminate the need for third-party antivirus solutions for many users. The blog highlighted that adequate security could be maintained with default settings, regular updates, and intentional software downloads. However, it also noted that users with specific needs, like managing multiple devices or requiring additional features, might still consider third-party software. The blog post was removed from the Microsoft Learning Center without formal announcement, raising questions about the company's communication strategy.

Subnautica 2’s no-killing policy isn’t because it’s ‘a game about pacifism’, says design lead, but because players would ‘master the crappy combat’ over anything else

Subnautica 2 has sparked controversy due to comments suggesting it lacks traditional combat elements. Design lead Anthony Gallegos explained that the decision to minimize combat is not based on a non-violent ethos but stems from the studio's modding culture origins. He referenced the developers of SOMA, highlighting that combat options could detract from the intended atmosphere of dread and exploration. By removing combat, Subnautica 2 aims to maintain tension and immersion in the underwater world. Gallegos also mentioned the possibility of new mitigation systems in future updates, as the episodic release schedule allows for the introduction of additional gameplay mechanics.

“I have proof for every single word”: This security researcher’s GitHub and Microsoft accounts were deleted after claiming a Windows 11 exploit in BitLocker is by design

A zero-day exploit named YellowKey was revealed by a researcher known as "Chaotic Eclipse" or Nightmare-Eclipse, which allows access to BitLocker-protected drives on Windows 11 using a USB key. Microsoft acknowledged the vulnerability, tracked as CVE-2026-45585, and provided mitigation strategies. The researcher expressed frustration over Microsoft's handling of the situation, including the banning of their GitHub account and lack of communication regarding unpaid bounties from Microsoft's MSRC program, which offers rewards for reporting vulnerabilities. Nightmare-Eclipse hinted at having evidence to support their claims and indicated plans to release documents related to the issue.

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.

CVE-2026-45585: YellowKey BitLocker Bypass

BitLocker, a security feature for data protection, has a vulnerability identified as CVE-2026-45585, also known as YellowKey, which allows unauthorized access to encrypted data on Windows 11 versions 24H2, 25H2, 26H1, and Windows Server 2025. This flaw does not compromise BitLocker’s encryption but affects the recovery environment supporting it. The vulnerability can be exploited locally through the Windows Recovery Environment (WinRE) by an attacker with physical access, who can trigger an unrestricted shell and access the BitLocker-protected volume. Microsoft has provided two mitigation strategies: modifying the WinRE image to remove the autofstx.exe entry and transitioning from TPM-only protection to a TPM+PIN requirement at startup. The exploit poses challenges for detection, as it occurs pre-boot and currently lacks vendor-published indicators of compromise. Organizations using BitLocker for unattended devices are particularly at risk, as the vulnerability can lead to loss of confidentiality if an attacker gains access before the legitimate user.

Microsoft says public sharing of Windows 11 vulnerability violates ‘best practices’

A security researcher known as Nightmare-Eclipse revealed a vulnerability in Windows 11, named YellowKey, which allows attackers to access BitLocker-encrypted drives through the Windows Recovery Environment. Microsoft acknowledged the vulnerability, assigned it the identifier CVE-2026-45585, and criticized the public sharing of its proof of concept. Currently, there is no patch available for the BitLocker bypass, but physical access to the device provides some protection. The vulnerability does not exist in Windows 10 due to differences in the Windows Recovery Environment. The attack requires a stolen Windows 11 laptop and a USB stick, and the vulnerable filesystems include NTFS, FAT32, and exFAT. Nightmare-Eclipse speculated that the bypass may function as a backdoor, while Microsoft referred to it as a "security feature bypass vulnerability."

CVE-2024-55638: Highly Critical Drupal Core Vulnerability Threatens PostgreSQL Sites with Remote Code Execution (RCE)

A critical vulnerability, CVE-2024-55638, has been identified in Drupal Core, affecting installations using PostgreSQL as their backend database. This vulnerability involves PHP Object Injection, which can lead to full Remote Code Execution (RCE) when combined with another deserialization flaw. It cannot be exploited independently but increases the risk for Drupal installations that use third-party modules or custom code that improperly employs the unserialize() function. The affected versions include Drupal Core 7.x prior to 7.102, 8.0.0 and above prior to 10.2.11, and 10.3.0 prior to 10.3.9, with patched versions being 7.102, 10.2.11, and 10.3.9. The vulnerability is particularly relevant for sites using PostgreSQL, and organizations are urged to upgrade to the patched versions and audit their code for unsafe unserialize() usage. Currently, there are no confirmed reports of exploitation in the wild, but the risk remains high due to insecure deserialization bugs in third-party modules. The EPSS score for this vulnerability is 9.93%, indicating a significant likelihood of exploitation in the near future.
