Backstage Ditches Postgres for Databricks Lakebase

The divide between operational and analytical databases is diminishing, as evidenced by Databricks integrating Spotify's Backstage with its Lakebase, transitioning from PostgreSQL to a unified data platform. Lakebase now offers a serverless PostgreSQL interface within Databricks, allowing Backstage to operate without awareness of the underlying changes. The integration involved updating configurations and addressing authentication challenges using OAuth JWTs. The integration transforms the database development lifecycle by enabling near-instant database branching through Lakebase's copy-on-write architecture, allowing developers to focus on testing changes rather than safety. Branching creates a pointer to existing data, making the operation instantaneous. Point-in-Time Recovery (PITR) allows for quick restoration of data, demonstrated by a recovery process that took less than four seconds. The goal is to integrate database branching into developer workflows seamlessly, making it automatic. This change could enhance developer productivity by allowing live data testing from the start, eliminating the need for mock objects, and resolving common issues related to staging environments. The traditional constraints of slow and costly database copies will become obsolete, prompting teams to reconsider how much time they spend on workarounds for now-nonexistent constraints.

LofyStealer Targets Minecraft Players via Node.js Loader and Browser Injection

Minecraft players are being targeted by a deceptive hacking tool called “Slinky,” which is actually an infostealer known as LofyStealer linked to the Brazilian cybercrime group LofyGang. The malware uses a Node.js-based loader and a C++ payload to extract sensitive browser data, disguising itself as a Minecraft hack. It primarily targets younger players who may unknowingly execute it. The malware operates through a two-stage architecture, with a 53.5 MB loader binary that injects a smaller 1.4 MB payload into browser processes, bypassing detection methods. It collects sensitive information such as cookies, passwords, and credit card details, compressing and encoding the data for exfiltration. The command-and-control (C2) infrastructure is hosted in Brazil, and the malware's design reflects advanced compilation techniques. The campaign is attributed to LofyGang, which has evolved into a more professional entity, posing severe risks to players who download cheats and cracked tools. Indicators of compromise include a specific C2 IP address and associated endpoints.

LofyStealer Uses Node.js Loader Against Minecraft Gamers

Cybersecurity threat hunters have discovered an active infostealer campaign targeting the gaming community, involving malware called LofyStealer (or GrabBot) that disguises itself as a Minecraft hack named “Slinky.” The attackers use the official game icon to trick young gamers into executing the malware. The Brazilian cybercrime group LofyGang has enhanced its technical capabilities, utilizing a sophisticated two-stage modular architecture. The initial stage features a 53.5 MB loader file named load.exe, which is a Node.js runtime environment that obscures malicious signatures. The loader connects to the attacker’s server and decrypts a 1.4 MB C++ payload, chromelevator.exe, which targets eight web browsers to extract sensitive information like cookies and passwords. The stolen data is compressed, encrypted, and sent to the attacker’s server. LofyGang has evolved into a Malware-as-a-Service platform, offering a web panel for operators to monitor victims and generate custom executables. The campaign highlights the increasing threats to the gaming community, with advanced evasion techniques being employed by cybercriminals. Security professionals are advised to monitor network traffic and conduct audits for suspicious activities.

Google AI is creeping into every app on your phone. Here is how to disable it

Google has integrated its Gemini AI into various applications, including Gmail, Google Drive, Messages, and Google Photos. There is no universal switch to disable AI across Android devices due to varying manufacturer implementations. Users can selectively disable AI features in specific apps: - Google Messages: Disable Gemini by going to Messages settings and turning off the Gemini option. - Gmail: Turn off Smart features in Google Workspace and other Google products through the Gmail settings. - Google Photos: Disable Gemini features in Photos settings under Preferences. - Phone app: Disable AI features like Call Screen in the Phone app settings under Call Assist. - Pixel Screenshots: Disable the AI feature for searching screenshots in the Pixel Screenshots app settings. Disabling the Gemini app itself will remove its integrations and deactivate AI features on the device.

Inside the Architecture of an MCP Server for PostgreSQL

The Model Context Protocol (MCP) serves as a standard interface between large language models (LLMs) and external systems like PostgreSQL, emphasizing the importance of control over mere connectivity. An MCP server must act as a mediation and policy layer, enforcing security boundaries and ensuring that connections default to read-only. It should validate AI-generated SQL as untrusted input, encapsulate queries within transactions, and apply execution-time controls. The server must separate query generation from execution approval to manage operational costs and enforce guardrails on query types, such as limiting the number of rows returned. Token efficiency is crucial, with design considerations for compact data representation and schema introspection. In production, connection management is vital to prevent data leakage among multiple AI agents, and observability through logging executed queries and metadata is necessary for debugging and compliance. Long-running sessions require support for paginated responses to manage context effectively. Overall, the MCP server must integrate security, query safety, token efficiency, and observability into its design from the outset.

‘Eventually the slop will just fall to the bottom’: Garry’s Mod sequel launches to ‘mixed’ reviews, but Garry himself isn’t worried about AI games on the main page

s&box, the successor to Garry's Mod, has been unveiled as an open-source platform aimed at a mature audience, similar to Roblox. It has received a mixed reception on Steam, with many negative reviews citing issues related to AI-generated content. The platform features hastily assembled games, including one titled Terry's Granny (Now with Co-op!). Newman from Facepunch stated that while the studio does not encourage using AI for game creation, they recognize its value as a learning and productivity tool. He emphasized the importance of human creativity and a balanced approach to AI use, suggesting a 50/50 method. Newman mentioned that Facepunch uses AI mainly in early pre-production phases and views it as a tool for learning rather than a replacement for creative processes. He believes that low-quality AI-generated content will eventually be disregarded by users. S&box is now available on Steam for users to explore and contribute to its community.
