How to create a Metabase dashboard with Docker

Creating a self-hosted analytics dashboard using Metabase and Docker involves deploying the Metabase container, which integrates with PostgreSQL for data storage. The prerequisites include a server or local machine with Docker, terminal access, an available port (typically 3000), a PostgreSQL database, and connection details for the business database. The installation steps are as follows: 1. Pull the Metabase Docker image using `docker pull metabase/metabase:latest`. 2. Run the Metabase container with `docker run -d -p 3000:3000 --name metabase metabase/metabase`. 3. Verify the container operation using `docker ps` and check logs with `docker logs -f metabase`. 4. Access the Metabase setup wizard at `http://localhost:3000` or `http://your-server-ip:3000`. 5. Manage the Metabase container using `docker stop metabase`, `docker start metabase`, and `docker restart metabase`. For a production setup, it is recommended to integrate PostgreSQL for persistent storage. Steps include creating a project directory, a Docker Compose file, launching both Metabase and PostgreSQL containers, monitoring logs, accessing Metabase, managing the deployment with Docker Compose commands, and updating Metabase by pulling the latest image. To create a business intelligence dashboard, connect your business data source by selecting the database type and entering connection details. Create questions using the visual query builder or SQL, choose suitable visualizations, compile saved questions into dashboards, add filters for interactivity, and share the dashboard with stakeholders while managing permissions.

Windows zero-days expose gaps in built-in security protections

Two Windows zero-day vulnerabilities, YellowKey and GreenPlasma, have been identified. YellowKey targets the Windows Recovery Environment (WinRE) on Windows 11 and Windows Server 2025, allowing attackers with physical access to bypass BitLocker protections using a USB device. GreenPlasma affects Windows 10, Windows 11, and Windows Server environments with active Collaborative Translation Framework Monitor (CTFMON) sessions, enabling local privilege escalation from a standard user account to SYSTEM-level privileges. Both vulnerabilities require either physical or local access to exploit. Microsoft has not yet released patches for these vulnerabilities, prompting organizations to enhance their security measures and operational resilience. Recommendations include reassessing physical security, limiting local administrative access, and implementing multifactor authentication and robust credential management practices.

Nvidia tells users to update GPU drivers now or face possible attack — here’s what we know

NVIDIA has released an update to its GPU display drivers that addresses 14 vulnerabilities across its product lines, including GeForce, RTX, Quadro, Tesla, NVS, vGPU, and Cloud Gaming software. The most critical vulnerability is CVE‑2026‑24187, a high-severity use-after-free bug rated 8.8 out of 10, which could allow code execution, privilege escalation, data theft, or system crashes. Linux systems are vulnerable due to improper access to GPU resources at the kernel level, while Windows systems are at risk from a timing flaw. Two vulnerabilities in NVIDIA’s Unified Virtual Memory subsystem on Linux could lead to denial-of-service attacks without elevated permissions. The vGPU software also received patches for vulnerabilities in its virtual GPU manager component. Users can download the updated drivers from the NVIDIA Driver Downloads page or the NVIDIA Licensing Portal, with Windows users needing version 569.49 or newer and Linux users needing version 590.48.01. Users are advised to maintain their antivirus programs for enhanced security. NVIDIA thanked external security researchers for their responsible disclosure of these vulnerabilities.

Binance’s Android app privacy fight is back in the spotlight

Binance is facing scrutiny regarding the data collection practices of its Android app, which some users believe functions more as a data collection tool than a trading platform. Concerns have been raised about the app's extensive permissions and tracking capabilities, with a report indicating the presence of numerous tracking components, including SDKs from TikTok and WeChat, and over 50 system permissions. Binance's privacy portal states that data is collected for account management, security, marketing, fraud prevention, and legal compliance. Despite this, there are questions about whether the data collection practices are proportionate to the app's intended functions. Binance has a history of legal issues, including a guilty plea in November 2023 that resulted in a .32 billion penalty for anti-money laundering violations. The exchange claims to tailor its privacy framework to regional regulations, but user concerns about the app's tracking capabilities persist. As of early 2026, Binance has over 300 million registered users, making any privacy-related disputes potentially impactful. The ongoing scrutiny may lead to gradual adjustments in Binance's practices rather than a complete overhaul.

Beware of Activating Them: 5 Android App Permissions That Pose a Threat to Your Data

Android applications often request various permissions upon installation, including access to the camera, microphone, contacts, messages, and accessibility features. Users frequently accept these requests without hesitation, which can compromise their device's privacy and security. Certain permissions, if granted to malicious apps, can enable monitoring of user activity, audio recording, location tracking, or unauthorized app installations. Five Android app permissions that require careful consideration before granting include: 1. Accessibility Services: Can allow untrusted apps to monitor screen content, read messages, track keystrokes, and perform actions on behalf of the user. 2. Display Over Other Apps: Allows apps to overlay content on other apps, which can be exploited by malicious apps to create deceptive interfaces. 3. Install Unknown Apps: Permits apps to install software from outside the Google Play Store, increasing the risk of malware. 4. Usage Data Access: Enables apps to monitor usage patterns, which can be used for targeted advertising or sold to data brokers. 5. Access to Contacts and Messages (SMS): Sensitive information can be intercepted by malicious apps, posing risks to account security. It is crucial to grant permissions that align with an app's intended function and to be cautious of unnecessary access.
