Blizzard is keeping secrets about Diablo 4’s next season until BlizzCon, but you can still try some of it out next week

Blizzard will reveal detailed patch notes for Diablo 4's upcoming season 15 at BlizzCon in September, marking a departure from their usual practice of providing advance details. The season will introduce new seasonal items, returning favorites, and adjustments to the Mythic Unique item system. New features include "Challenge Dungeons," which are boss encounters with customizable difficulty in the open world, and "Overland Ambushes," where players must react quickly to being hunted by a demon. Players can expect new items called "Soul Splinters" that enhance jewelry with damage buffs, and revamped Unique items from previous games, such as Leoric's Crown. The season will also see the return of the "Rebirth" system from Diablo 3 and changes to the Mythic Uniques, including the introduction of weaker, Unique versions of Iconic Mythics. A public test realm (PTR) for these features will be available from August 4 to August 11.

Scrappy RAT Malware Targets Chrome And Edge Users

A new remote access trojan (RAT) named msaRAT has been identified by Cisco Talos, linked to the Chaos ransomware group and built using Rust. It exploits Chrome and Edge browsers to disguise its traffic and evade detection. MsaRAT operates through a headless browser process, enabling remote code execution and facilitating ransomware deployment, data theft, and other malicious activities. It is typically installed via phishing emails or malicious files, making it resistant to standard browser patches. Cisco Talos recommends specific SNORT rules and a ClamAV signature for detection. Indicators of Compromise (IoC) include traffic to the IP address 172.86.126.18 and the domain is-01-ast.ols-img-12.workers.dev. The malware primarily targets large organizations, but individual users may also be at risk.

Microsoft making a new feature mandatory requirement for Windows KMS activation

Microsoft has introduced enhancements to its Windows operating system security, including an update to Entra ID authentication with default passkeys and AI-enhanced security updates. A key advancement is the KMS Hardware-Secured initiative, which uses Trusted Platform Module (TPM)-based attestation to ensure KMS hosts operate on trusted hardware for Windows volume activation. This aims to combat risks from counterfeit KMS servers. Under the new model, KMS hosts will confirm their hardware identity using TPM before activating Windows devices. Starting in August 2026, Windows Server 2025 will provide readiness messaging for KMS host compliance with new security requirements. TPM attestation will be mandatory for KMS Hardware-Secured activation with the upcoming Windows Server 2028 LTSC release. Organizations are advised to prepare for this transition.
Running pgvector in production on Amazon Aurora PostgreSQL

Running pgvector in production on Amazon Aurora PostgreSQL

Running pgvector on Amazon Aurora PostgreSQL-Compatible Edition offers a vector store with operational capabilities, high availability, and scalability. It is favored for Retrieval Augmented Generation (RAG) workloads transitioning to production, but increased traffic introduces challenges like query latency and memory management. Key operational practices for pgvector workloads include selecting the appropriate index type (HNSW or IVFFlat), establishing a baseline schema, choosing a suitable distance operator, scaling the index through quantization and partitioning, and preparing for churn and observability. The prerequisites for using pgvector include an Aurora PostgreSQL-Compatible cluster with specific PostgreSQL versions and the vector extension enabled. The embedding model used in examples is Amazon Titan Text Embeddings V2, which produces 1024-dimensional embeddings. pgvector supports two Approximate Nearest Neighbor (ANN) index types: HNSW, which is efficient for querying and allows for incremental insertions, and IVFFlat, which is less resource-intensive but requires rebuilding if data changes. There are scenarios where forgoing an index is beneficial, such as small datasets or partitioned datasets requiring 100% recall. A baseline schema for a multi-tenant document store includes creating a table for documents with an embedding vector and establishing indexes for tenant IDs and embeddings using HNSW. The recommended parameters for HNSW include m = 16 and ef_construction = 128. Scaling to millions of vectors involves quantization, tuning HNSW parameters, and partitioning. Aurora Optimized Reads can extend effective cache capacity, and managing index churn is crucial for maintaining performance. Observability metrics include query-level statistics, instance-level metrics, and custom application-defined metrics. To clean up after testing, it is advisable to drop the created indexes and tables, and delete the Aurora PostgreSQL-Compatible cluster and any manual snapshots taken during testing.

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.

PostgreSQL Extensions Are an Architecture Decision, Not an Afterthought

A common issue in database migrations is the unplanned accumulation of extensions in PostgreSQL, leading to extension sprawl. Teams often install extensions without documenting the rationale, resulting in a complex web of dependencies that complicates future upgrades and removals. The installation process involves PostgreSQL accessing a control file that details the extension's version and dependencies, which can lead to multiple extensions being installed unintentionally. Upgrading and removing extensions are often neglected, causing risks such as the loss of dependent objects. Extensions typically default to the public schema, which can become cluttered; relocating them to dedicated schemas can improve organization. Trusted Language Extensions (TLE) allow non-privileged users to utilize procedural languages in managed databases without needing superuser access. Key extensions recommended for use include pg_stat_statements, pg_trgm, hstore, citext, and PostGIS, each serving specific use cases. Proper governance is essential for managing extensions, including documenting their purpose, ownership, and dependencies, to prevent operational surprises.
