Google Messages will finally tell you when your custom ROM is the problem (APK teardown)

Google has implemented a measure to enhance the security of its messaging platform by preventing devices that fail Play Integrity checks from sending Rich Communication Services (RCS) messages. This decision has led to users experiencing vanished messages without explanation, particularly affecting those with rooted phones or custom ROMs. Recent developments indicate that Google Messages will now inform users when their devices do not meet security requirements, with a new text string stating, "Your device does not meet security requirements," expected to appear in the RCS settings. Additionally, a "Details" button is anticipated to provide further clarification on RCS limitations. This change aims to improve user communication and reduce confusion regarding message disappearances.

Microsoft Ends Windows 11 SE: Support Ceases in 2026

Microsoft launched Windows 11 SE in late 2021 to compete with Google’s Chrome OS in the education technology sector, targeting low-cost devices for schools with a starting price around . The operating system was designed for Chromebook-like laptops, featuring restrictions on app installations to focus on educational tools and integration with Microsoft services like Office 365. Initial interest was noted, but adoption faced challenges due to schools' commitments to Chromebooks and limited app compatibility. By 2022, devices with Windows 11 SE appeared in schools, but market penetration remained modest, hindered by hardware requirements and competition from Chromebooks. Microsoft announced the discontinuation of Windows 11 SE in 2025, with support ending in October 2026, necessitating migration for schools using the OS. This decision reflects a strategic shift towards cloud-based solutions and highlights the challenges of competing against established platforms like Chrome OS.

Windows 10 is ten years old and it had some of the best and worst ideas ever

Windows 10 was a significant advancement for Microsoft, introducing features like Cortana, a digital assistant, and Windows Hello, a biometric security feature. It celebrated its tenth anniversary but is set to retire in October 2025, with Microsoft ending support for it. Despite the rise of Windows 11, which faced criticism for its TPM 2.0 security requirements, Windows 10 maintained a strong user base until recently. Additional features included the Action Center and the Xbox App, while some elements from Windows 8 persisted. Cortana was designed to enhance user interaction, but Windows 11's changes have been viewed as less inclusive, impacting users with older PCs.

Securing the Model Context Protocol: Building a safer agentic future on Windows

The Model Context Protocol (MCP) is a lightweight, open protocol functioning as JSON-RPC over HTTP, facilitating standardized discovery and invocation of tools. MCP defines three roles: MCP Hosts (applications accessing capabilities), MCP Clients (initiators of requests), and MCP Servers (services exposing functionalities). Windows 11 will incorporate MCP to enable developers to create intelligent applications leveraging generative AI. An early preview of MCP capabilities will be available for developer feedback. MCP introduces security risks, including cross-prompt injection, authentication gaps, credential leakage, tool poisoning, lack of containment, limited security review, registry risks, and command injection. To address these, Windows 11's MCP Security Architecture will establish security requirements for MCP servers, ensuring user safety and transparency, enforcing least privilege, and implementing security controls like proxy-mediated communication, tool-level authorization, a central server registry, and runtime isolation. MCP servers must comply with security requirements, including mandatory code signing, unchanged tool definitions at runtime, security testing, mandatory package identity, and declared privileges. An early private preview of MCP server capability will be offered to developers post-Microsoft Build for feedback, with a secure-by-default enforcement strategy planned for broader availability. Microsoft aims to enhance defenses continuously and collaborate with partners to bolster MCP's security framework.

Microsoft’s Free Windows Upgrade—When Does Offer Expire?

Microsoft is facing a challenge as the end of life for Windows 10 approaches in October, with hundreds of millions of users yet to transition to Windows 11. Throughout 2024, there has been a modest migration to Windows 11, but Windows 10 has recently regained some users. The transition to Windows 11 is free for licensed Windows 10 users whose hardware meets the necessary requirements, but if a PC fails the technical assessment, the free upgrade is not available. Initially, there was a belief that the free upgrade would be time-limited, but this guidance has been revised, and the deadline has been removed. Microsoft has not officially confirmed whether the free upgrade will remain available after the October end-of-life date for Windows 10. Currently, Microsoft states that the free upgrade offer does not have a specific end date but reserves the right to end support for it. Users are encouraged to upgrade before the October 14th deadline, as security updates will cease after that date. Estimates indicate that 300 to 400 million users are still eligible for the upgrade but have not yet acted, with many potentially needing new hardware. Upgrading an incompatible PC may lead to loss of support, leaving users with the options to pay for a support extension or buy a new PC.

Simplify database authentication management with the Amazon Aurora PostgreSQL pg_ad_mapping extension

Authentication is essential for security in enterprise environments, protecting sensitive data and resources from unauthorized access. Kerberos authentication is utilized for Amazon Aurora PostgreSQL-Compatible Edition with AWS Directory Service for Microsoft Active Directory, particularly through the pg_ad_mapping extension, which enhances access control management. Aurora PostgreSQL supports multiple authentication methods, including password authentication, AWS Identity and Access Management (IAM) database authentication, and Kerberos authentication. By default, password authentication is enabled, while IAM and Kerberos can be used independently. Users are assigned specific roles based on the authentication method: rds_iam for IAM, rds_ad for Kerberos, and no specific roles for password authentication. Kerberos authentication integrates with Microsoft Active Directory, allowing centralized authentication and single sign-on (SSO) capabilities. With versions 14.10 and 15.5, Aurora PostgreSQL introduced the pg_ad_mapping extension, which allows administrators to manage access through Active Directory (AD) security groups instead of provisioning individual users. This extension checks AD group memberships upon user login and assigns corresponding database roles, prioritizing roles based on assigned weights. The pg_ad_mapping extension includes functions such as pgadmap_set_mapping to add mappings between AD security groups and database roles, pgadmap_read_mapping to list existing mappings, and pgadmap_reset_mapping to delete or reset mappings. To deploy the solution, a CloudFormation stack is used to create necessary resources, including an AWS Managed Microsoft AD server, an Aurora PostgreSQL database cluster, and a Windows EC2 instance. Users can be added to AD groups, and roles can be mapped to facilitate access management. Security best practices for Aurora PostgreSQL include using IAM policies for resource management, implementing security groups for database access control, utilizing encryption for data protection, and employing Transport Layer Security (TLS) for secure connections. For auditing, the pg_stat_gssapi view can be used to identify authenticated users, and enabling the log_connections parameter will log session establishments, including AD user identities.
