Building Deterministic Security Boundaries for AI Agents on AWS
This story was originally published on HackerNoon at: https://hackernoon.com/building-deterministic-security-boundaries-for-ai-agents-on-aws. Explore how to secure autonomous AI agents on AWS using isolated execution, least-privilege IAM, tool validation, recovery controls, and kill switches.

This story was written by: @kiranvm. Learn more about this writer by checking @kiranvm's about page, and for more stories, please visit hackernoon.com. Autonomous AI agents can interact with sensitive infrastructure, making indirect prompt injection and unauthorized tool execution serious security concerns. This article proposes four defensive layers for AWS-hosted agents: isolated execution environments, deterministic validation of tool calls, recovery mechanisms, and execution-level interruption controls. While these approaches offer a useful starting point, the proposed implementations require more precise authorization, validation, rollback, and human-approval mechanisms before they can be considered production-ready.

How Drones Navigate Without GPS: A Builder's Guide to Visual SLAM in 2026
This story was originally published on HackerNoon at: https://hackernoon.com/how-drones-navigate-without-gps-a-builders-guide-to-visual-slam-in-2026. Explore how visual SLAM enables GPS-denied drone navigation, from visual-inertial odometry and mapping to edge AI, path planning, and limitations. Check more stories related to tech-stories at: https://hackernoon.com/c/tech-stories. You can also check exclusive content about #drone-technology, #uavs, #computer-vision, #visual-slam, #gps-denied-navigation, #autonomous-drones, #visual-inertial-odometry, #edge-ai-for-drones, and more. This story was written by: @vishwagw. Learn more about this writer by checking @vishwagw's about page, and for more stories, please visit hackernoon.com. GPS is no longer a safe assumption. Jamming and spoofing are routine around conflict zones and have spilled into civil aviation. A drone that only knows where it is through GNSS is one jammer away from hovering in place or crashing. Visual SLAM (VSLAM) lets a drone estimate its own position and build a map of its surroundings from cameras, usually fused with an IMU. Cameras are cheap, light, and passive, which is why they suit small aircraft. The classical pipeline still carries the load: feature tracking → visual-inertial fusion → mapping with bundle adjustment and loop closure → path planning. ORB-SLAM3, VINS-Mono, and OpenVINS remain the reference implementations. What changed in 2025–2026: GPU-accelerated classical SLAM on edge hardware (NVIDIA cuVSLAM), foundation-model priors inside SLAM (MASt3R-SLAM), NMS-free edge detectors for filtering moving objects (YOLO26), and vision-based navigation fielded in Ukraine. Vision isn't magic. Darkness, smoke, featureless terrain, fast motion, and monocular scale ambiguity all break it. The honest design is a fusion stack where vision is the backbone, not the only sensor.

AI Can Remember Your Chats. Remembering Your Life Is Much Harder.
This story was originally published on HackerNoon at: https://hackernoon.com/ai-can-remember-your-chats-remembering-your-life-is-much-harder.

For AI to become truly useful in everyday life, it needs memory that goes beyond chat history. Building that memory means solving four key challenges: deciding what to remember, retrieving the right experience, connecting moments over time, and learning from corrections as people and circumstances change. At Looki, we’re exploring how visual evidence, supported by audio, chat, location, and other context, can create AI memory that is grounded in what actually happened—and remains understandable, verifiable, and correctable.

From Global Allowlist to RCE: Breaking Down CVE-2026-50023 in yt-dlp
This story was originally published on HackerNoon at: https://hackernoon.com/from-global-allowlist-to-rce-breaking-down-cve-2026-50023-in-yt-dlp.

This story was written by: @pavanchow. Learn more about this writer by checking @pavanchow's about page, and for more stories, please visit hackernoon.com. A fix for filename sanitization kept dangerous extensions on a global allowlist. I bypassed it by crafting an HLS manifest that forced yt-dlp to write a malicious .desktop file during a standard subtitle download. The patch moved the exception to the feature boundary, but a follow-up CVE proved the class was not fully closed.
