LG smart TVs caught logging audio with screen off and snooping on local devices

LG smart TVs caught logging audio with screen off and snooping on local devices

Gamers Nexus and security researchers found retail LG OLED TVs scanning local networks, collecting nearby Wi-Fi and device data, and potentially recording microphone audio in standby, uploading stored recordings later. The TVs also use Automated Content Recognition, while researchers identified webOS remote-code-execution vulnerabilities. They recommend disconnecting LG TVs from the internet; LG has not commented.

Delhi Cut Electricity Loss from 50 to 5 Percent

Delhi Cut Electricity Loss from 50 to 5 Percent

Delhi reduced electricity distribution losses from over 50% in 2002 to 5–6% in 2026 and raised grid reliability above 99.9%. The turnaround combined privatization, regulatory reform, infrastructure upgrades, SCADA, improved metering, capacitor banks, theft detection, workforce training, payment access, and community engagement—demonstrating that technology requires accountability and consumer participation.

It's not you; GitHub is down again

It's not you; GitHub is down again

GitHub has issued an alert regarding a service disruption where notifications are being delayed via email and text message. To keep users informed, GitHub is offering a subscription service for real-time incident updates. Users can opt-in for email alerts for every incident update or SMS notifications for the creation and resolution of issues. This service supports a vast global reach, including over 150 countries from Afghanistan to Zimbabwe. To enable SMS, users must perform a verification process involving a mobile number and a one-time password (OTP), ensuring secure and reliable communication during technical outages.

Iran Goes Into IPv6 Blackout

Iran Goes Into IPv6 Blackout

Cloudflare Radar provides critical insights into global internet infrastructure by monitoring BGP routing anomalies and table statistics. Recent reports investigate a specific BGP route leak incident in Venezuela, analyzing data to determine the underlying causes of such connectivity disruptions. Additionally, the concept of BGP zombies is explored, which refers to routes that remain stuck in the Default-Free Zone even after a prefix withdrawal should have occurred. The platform also emphasizes the importance of managing AS-SET memberships for an ASN to ensure routing integrity. These tools and analyses are essential for network operators to maintain security and performance within the complex ecosystem of global internet routing and to prevent potential traffic redirection or outages caused by configuration errors.

I think the military commissary's freezers were hacked

I think the military commissary's freezers were hacked

At least six U.S. military commissaries experienced near-simultaneous refrigeration failures, including Fort Huachuca, where every freezer entered defrost mode despite continuous power. DeCA documents show defrost is controlled through networked Refrigeration Monitoring and Control Systems (RMCS). A cyberattack remains unproven, but vulnerable commercial controllers, IoT exposure, and national-security warnings make coordinated interference a plausible hypothesis.

Claude Code for Infrastructure

Fluid is a specialized infrastructure automation tool designed to streamline development workflows through high-fidelity sandbox isolation. By allowing users to instantly clone VMs, Fluid provides a safe environment to test changes in isolation before they ever reach production. The system is context-aware, meaning it explores the host environment including the OS, installed packages, and CLI tools to adapt its behavior accordingly. Security and accountability are central features, offering a full audit trail where every command and change is logged for review. Furthermore, Fluid enhances reproducibility by auto-generating Ansible Playbooks based on the activities performed within the sandbox, bridging the gap between experimentation and production-ready infrastructure code.
