Hackers Use Fake CAPTCHA To Infect Windows PCs
Hackers are abusing fake CAPTCHA pages on compromised or malicious websites to trick Windows users into installing malware on their systems. These CAPTCHA pages mimic familiar “prove you’re human” checks, often styled like Cloudflare or other widely used services, but instead of a normal visual challenge they prompt users to manually execute seemingly simple actions—such as pressing Windows + R, pasting a copied command, and hitting Enter—to complete the verification. What victims don’t realize is that these steps execute a hidden PowerShell command that initiates the malware installation process. (GBHackers Security)

When to Break Out the Spectrum Analyzer
Ever wondered what really lurks in the airwaves around you? In this lively webcast recap, Dan Jones walks us through the magic behind spectrum analysers — the tool that turns unseen RF chaos into visual clarity. If you’ve ever tried to design or troubleshoot a Wi-Fi network, you know it’s not just about access points and antennas; you’ve got to understand the jungle of interference, noise, and signal strength that lives between 2.4 GHz, 5 GHz and beyond. This session demystifies how spectrum analysers measure that energy and why it matters.
But it’s not just theory. You’ll learn the real-world when: measuring noise floors to predict actual data rates, spotting rogue interference sources, and making smarter planning decisions. From crowded office environments to industrial floors with noisy gear, this webcast shows how and where spectrum analysis earns its keep — and where modern smart APs handle most of the heavy lifting on their own.

Don’t Ghost Your Wi-Fi. Why Post-Deployment Checkups Matter
Rolling out a new Wi-Fi network feels like crossing the finish line, but in reality, it’s more like the halfway point. Following up after deployment is where the real value shows up. It’s your chance to confirm that access points are behaving the way you intended, coverage is consistent, and users are actually getting the performance you designed for. Without that follow-up, small issues can quietly grow into big complaints later.
In the image I shared, it’s pretty obvious that users aren’t evenly distributed across the access points. One AP looks loaded while others are just hanging out, bored and underutilized. That imbalance might be due to AP placement, building layout, or client devices stubbornly sticking to a stronger-looking signal. Even if it’s “technically working,” it’s still worth digging into because uneven client distribution can tank performance for everyone connected to the busy AP.

From the web - Chris Greer and Dont Break DNS
Dive into the often-misunderstood world of DNS with **“Don’t Break DNS!! // Lesson 2”** from networking expert Chris Greer. While many assume DNS runs exclusively over UDP, this eye-opening episode in the "How DNS Works" series reveals the critical role TCP plays when responses grow too large for UDP packets. Using real-world examples and Wireshark packet captures, Chris demonstrates exactly what happens when a UDP reply gets truncated (the infamous TC flag), forcing the client to retry over a TCP connection. Whether you're troubleshooting mysterious resolution failures or simply want to deepen your understanding of core internet protocols, this lesson delivers clear, practical insights backed by key RFCs like 1123 and 5966.

Who Invited This access-point?
At first glance, a duplicate SSID might seem harmless. Maybe a neighbor named their Wi-Fi the same thing as yours, or someone plugged in a cheap router without telling you. But in practice, this can cause real problems. Client devices can roam to the wrong access point, leading to slow speeds, dropped connections, or users getting kicked off the network for no obvious reason. Worse, if that rogue access point isn’t secured properly, it can become a security risk or even a sneaky man-in-the-middle opportunity.

from the web : Why use a route map for redistribution?
The post explains why using a route-map when redistributing routes between protocols (like RIPv2 into OSPF) is important: without one, a router will redistribute all routes indiscriminately, which can cause routing loops, security issues, or unintended route propagation. A route-map gives fine control over which prefixes are shared and allows modification of route attributes such as metrics, metric types, and tags before redistribution. The article walks through a lab topology where RIPv2 routes from one router are selectively redistributed into an OSPF domain using access lists and a route-map that sets different metrics for specific prefixes, demonstrating the configuration and the resulting routing table.

Reserving an IP on a Cudy Router Without Losing Your Mind
If you’ve ever gone hunting for a simple “DHCP Reservation” option on a Cudy router, you’ve probably discovered that Cudy likes to play a little game of hide-and-seek with its terminology. The feature is there, it works well, but it’s not always called what you expect. That’s why reserving an IP on a Cudy router is one of those tasks that feels harder than it should—until you know where to look. Once you crack the language barrier, though, the process is straightforward and incredibly useful.
The big benefit of reserving an IP address is consistency. Devices like printers, servers, or cameras really don’t appreciate surprises, and neither do the apps or computers that talk to them. By reserving an IP, you’re telling your router, “Hey, this device gets this address every time—no exceptions.” In my case, I used an HP DeskJet 2600 as the example in the video, because printers are famous for breaking the moment their IP address changes. One reservation later, and those “printer not found” errors magically disappear.
