Critical NASA AIT-GUI Security Flaws Could Allow Unauthenticated Spacecraft Commands

A newly disclosed security issue affecting NASA/JPL's AMMOS Instrument Toolkit GUI (AIT-GUI) is a good reminder that traditional web application vulnerabilities can become extremely serious when they are connected to physical systems. AIT-GUI is used as a browser-based interface for controlling spacecraft and scientific instruments, and researchers found that affected versions exposed critical functions without proper authentication, authorization, or CSRF protection. In the worst-case scenario, an attacker who could reach the vulnerable service could potentially send commands to connected equipment without logging in. The advisory rated the issue Critical, with a CVSS score of 9.4, and identifies AIT-GUI versions 2.5.1 and earlier as affected.

12 Essential TCP Concepts Explained Simply — A Must‑Watch Deep Dive for Networking Pros

The video breaks down the Transmission Control Protocol (TCP) into 12 clear, digestible ideas that help viewers truly understand how data reliably moves across the internet. Instead of overwhelming you with jargon, it walks through each concept—like Sequence Numbers, Acknowledgment Numbers, and Window Size—in a way that feels intuitive and practical. Whether you're a student, a network engineer, or someone brushing up on fundamentals, this guide makes TCP’s inner workings feel accessible and even enjoyable.

Why "It's Probably the Cable" Should Send You to the Field

Every network tech has said it at least once: "It's probably the cable." And every network tech has also, at least once, been dead wrong about which cable, why, or how. If you've ever spent forty-five minutes staring at a switch port graph trying to divine the future from a packet loss chart, this one's for you. Nothing — and I mean nothing — replaces walking to the actual jack, patch panel, or connector and looking at it with your own two eyeballs. Due to recent advancements in technology you can do this remotely over a video call, i do it all the time.

The Lightning‑Bolt Express: When LapLink Ruled the Earth

Long before cloud storage, Wi-Fi, and services like OneDrive made moving files between computers almost effortless, there was LapLink. For many PC users, LapLink was one of the simplest ways to connect two computers and transfer files, folders, and settings. The software became especially popular during the DOS and early Windows era, when networking two PCs could be far more complicated than it is today. What looked like a simple yellow cable and a piece of software was actually a clever solution to a very common technical problem: how do you get data from one computer to another without a network?

Nine PBS’ 50TB Data Disaster: How 70 Years of TV History Got Trapped in the Cloud

Nine PBS in St. Louis has found itself dealing with a nightmare scenario for anyone responsible for long-term data storage: the data apparently still exists, but the organization can't access it. The public television station is fighting to recover more than 50 terabytes of archival material representing roughly 70 years of programming and regional history. The archive includes coverage of major events such as the Great Flood of 1993, the COVID-19 pandemic and the history of East St. Louis. The problem began when Nine PBS's cloud-storage provider, Open Source Storage (OSS), apparently ceased operations and stopped responding to the station. (link)
