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.

Signal isn’t broken — so how are hackers targeting the world’s ‘most secure’ chat app?

On April 26, hackers allegedly linked to Russian groups targeted the Signal messaging app with phishing attacks aimed at senior politicians. These attacks did not compromise Signal's end-to-end encryption; rather, they deceived users into providing access to their accounts through fake messages. Signal is operated by the non-profit Signal Foundation, founded in 2012 by Moxie Marlinspike with funding from Brian Acton, a co-founder of WhatsApp. Signal distinguishes itself by rendering metadata invisible to its operators, unlike WhatsApp, which shares user data with its parent company. Signal's president, Meredith Whittaker, advocates for data privacy.

Databricks Postgres Gets Customer Key Control

Databricks has introduced customer-managed keys (CMK) for its Lakehouse Postgres offering, allowing users to control their data encryption and utilize their own Key Management Service (KMS) from major cloud providers like AWS KMS, Azure Key Vault, or Google Cloud KMS. The Lakehouse Postgres architecture features a hierarchical envelope encryption model with three tiers: the customer-managed root key (CMK), a Key Encryption Key (KEK) used by Databricks' Key Manager Service, and unique Data Encryption Keys (DEKs) for each data segment. If a CMK is revoked, access to the data is denied, and active compute instances are terminated, serving as a failsafe for high-compliance workloads. The implementation allows for granular control over key management and supports seamless key rotation without data re-encryption or downtime. All cryptographic operations are logged within the customer's cloud audit services, available to Databricks Enterprise tier customers.

If you ever need truly private photos on Android, this is the camera app to use

Smartphone manufacturers have focused on improving megapixels and zoom capabilities in camera technology while neglecting user security features. Major camera apps from companies like Google and Samsung lack immediate methods to protect sensitive information at the point of capture. A recent poll indicated that 71% of respondents believe privacy-focused features are necessary in camera apps. SnapSafe is an application designed to enhance privacy by operating without internet permissions, allowing for encrypted image capture, editing, and storage. Users must set a PIN to secure the app, and it includes features like a "Poison Pill" for deleting images with a secondary PIN, decoy photographs for security, and automatic face obfuscation. Despite some shortcomings, such as delays in image capture and limited image management features, SnapSafe is recognized as a leading private camera app for Android, highlighting the demand for privacy-centric technology in photography.

Guardian source messaging tech bringing in ‘much higher quality’ of tips

The Guardian's secure messaging technology, launched in June, has significantly improved the quality of tips from sources, utilizing advanced encryption techniques to ensure confidentiality. The app allows messages to vanish after 14 days and is designed to protect sources' anonymity better than many other encrypted services. It has been recognized as a finalist for a major award and has led to a notable increase in story tips, particularly from the U.S. and Australia, despite its primary user base being in the UK and Europe. The app operates independently of The Guardian's paywall, enabling non-paying users to submit tips freely. The platform encourages contributions from users who may have felt intimidated by other secure methods. The technology enhances communication quality and allows sources to provide context to existing stories. As of September, the app has one million daily active users, with features that obscure genuine communications among automated messages, contributing to source protection. The Guardian has invested in guiding sources on crafting effective tips and has made the secure messaging technology open source for other newsrooms to adopt, aiming to improve source protection across the industry. Collaborations with organizations like The Signals Network and the University of Cambridge are ongoing to gather feedback and enhance the technology further.

Microsoft to Block Windows 11 and Server 2025 Automated Installation After Critical RCE Vulnerability

Microsoft is implementing a two-phase initiative to disable the hands-free deployment feature in Windows Deployment Services (WDS) due to a critical remote code execution vulnerability (CVE-2026-0386) identified on January 13, 2026. This vulnerability arises from improper access control related to the Unattend.xml file, which is transmitted over an unauthenticated RPC channel, allowing attackers on the same network segment to exploit it. Successful exploitation could grant SYSTEM-level privileges and compromise OS deployment images. The initiative includes: - Phase 1 (January 13, 2026): The hands-free deployment feature will remain operational but can be disabled. New Event Log alerts and registry key controls will be introduced to enforce secure practices. - Phase 2 (April 2026): The hands-free deployment feature will be completely disabled by default for administrators who have not modified registry settings. Administrators can temporarily re-enable the feature by setting AllowHandsFreeFunctionality = 1, but this is not secure. Recommendations include reviewing WDS configurations, applying security updates, setting registry keys for secure behavior, monitoring Event Viewer for alerts, and considering alternative deployment methods. Microsoft’s KB article 5074952 provides further guidance for impacted organizations.
