What Is Serverless PostgreSQL?

Serverless PostgreSQL is a fully managed cloud database model that separates compute and storage, allowing them to scale independently and automatically based on demand. It eliminates the need for manual infrastructure provisioning and capacity planning, charging only for active usage. Unlike traditional PostgreSQL setups, which require continuous resource allocation and manual scaling, serverless PostgreSQL provisions resources on demand and can scale down to zero during idle periods. Serverless PostgreSQL integrates with serverless compute platforms, enabling analytical queries to access the same data within a unified architecture. Key differences between traditional and serverless PostgreSQL include manual versus automatic provisioning and scaling, fixed versus usage-based billing, and high versus reduced operational overhead. Lakebase architecture is an emerging model that combines transactional databases with lakehouse foundations, allowing operational and analytical workloads to coexist on a single platform. This architecture minimizes data duplication and simplifies access, enhancing data management and analysis. Serverless PostgreSQL operates on a cloud-native architecture that enhances efficiency by allowing compute and storage to scale autonomously. It features scale-to-zero behavior, where compute resources are suspended when inactive and reactivated upon new queries. Major providers include Databricks Lakebase, Amazon Aurora Serverless v2, and Neon, each offering varying capabilities and integrations. Pricing for serverless PostgreSQL typically includes charges for compute resources, storage, and data transfer, with costs fluctuating based on workload activity. Cold start latency is a performance consideration, as reactivating compute resources can introduce delays. Strategies to mitigate this include keeping resources partially active or selecting providers with minimal cold start impacts. Serverless PostgreSQL is well-suited for OLTP workloads, while lakebase architecture is better for AI development, variable workloads, and environments requiring rapid iteration. Setting up serverless PostgreSQL involves choosing a provider, creating a database instance, and configuring access settings. It can also be used alongside serverless compute platforms for analytics, further extending its capabilities.

AI Threat Forces Microsoft To Update Windows Patch Guidance

Microsoft is advocating for a reevaluation of Windows patch management practices due to the rapid evolution of artificial intelligence (AI) impacting cybersecurity. The company emphasizes that traditional timelines for patch deployment, typically spanning several weeks after the monthly Patch Tuesday, are inadequate against modern cyber threats. Microsoft recommends organizations shorten deployment windows to under three days for quality updates, with immediate installation deadlines and minimal user grace periods. To support these changes, Microsoft is enhancing Windows Autopatch with a new reporting dashboard for patch compliance and security insights. The company is promoting cloud-managed deployment through Microsoft Intune and Windows Autopatch while continuing to support legacy tools. Additionally, Microsoft is introducing Windows Hotpatch technology, allowing security updates to be installed without immediate reboots, and advocating for the use of identity-based access controls to isolate unpatched devices. The guidance reflects a shift from scheduled patching to continuous risk management, encouraging organizations to prioritize high-risk assets and automate update deployments. Microsoft is also investing in AI-assisted vulnerability discovery and automated code analysis to improve defensive capabilities. The overarching message is that enterprises must adapt their update strategies to address the accelerated pace of AI-driven exploitation.

GigaWiper: Anatomy of a destructive backdoor assembled from multiple malware

Microsoft Threat Intelligence has identified the GigaWiper malware, which has been detected in compromised environments since October 2025. This malware has destructive capabilities and comes in two forms: standalone wiper binaries and larger binaries with backdoor functionalities, both developed in Golang. The standalone wiper operates at the physical disk level, overwriting disk content and removing partition references. The backdoor variant includes the same wiper functionality and adds persistence through a registry key and scheduled tasks, along with command and control communication via RabbitMQ and Redis. GigaWiper can execute various commands, including wiping drives, triggering a Blue Screen of Death (BSOD), file encryption that mimics ransomware behavior, and managing system elements. The malware integrates components from multiple malware families, including wipers and ransomware mechanisms, and has been linked to a previous malware known as FlockWiper. To defend against GigaWiper, organizations are advised to implement security measures such as tamper protection, blocking access to known C2 infrastructure, and utilizing endpoint detection and response solutions. Microsoft Defender provides detections for GigaWiper and related malware, and threat intelligence reports are available for customers to stay informed about threats. Indicators of compromise include specific SHA-256 hashes and IP addresses associated with GigaWiper.

Active Exploitation of Critical CVE-2026-20253 in Splunk Enterprise: Unauthenticated RCE via PostgreSQL Sidecar Service

A critical security vulnerability, SVD-2026-0603 (CVE-2026-20253), has been identified in Splunk Enterprise versions 10.0.0 through 10.0.6 and 10.2.0 through 10.2.3. This flaw allows unauthenticated, remote attackers to create or truncate arbitrary files on the host system by exploiting the PostgreSQL Sidecar Service endpoints. The vulnerability is actively exploited, with public proof-of-concept code available, and has been added to the CISA Known Exploited Vulnerabilities (KEV) list. Successful exploitation can lead to full remote code execution (RCE) as the Splunk user. The vulnerability arises from inadequate authentication controls on the PostgreSQL Sidecar Service endpoints, specifically /v1/postgres/recovery/backup and /v1/postgres/recovery/restore, which are accessible without authentication. It is classified under CWE-306: Missing Authentication for Critical Function and has a CVSS v3.1 base score of 9.8 (Critical). Attackers can exploit the vulnerability by sending crafted HTTP POST requests to the exposed endpoints, allowing them to create or truncate files and potentially execute malicious scripts. Indicators of compromise include unexpected files in directories such as /tmp/ or /opt/splunk/var/run/supervisor/pkg-run/, modified Splunk Python scripts, and unusual outbound connections from Splunk to unknown PostgreSQL servers. The vulnerability aligns with several MITRE ATT&CK techniques, including T1190 (Exploit Public-Facing Application) and T1059 (Command and Scripting Interpreter). Active exploitation of CVE-2026-20253 has been confirmed, and it is likely that both opportunistic cybercriminals and sophisticated threat actors will use this exploit.
