Wi-Fi Vulnerability in Microsoft Windows

Wi-Fi Vulnerability in Microsoft Windows

Microsoft has officially acknowledged a recently discovered Wi-Fi vulnerability in its Windows operating system. Using the Common Vulnerability Scoring System, or CVSS, the threat has been assessed as having a severity rating of 8.8 out of 10. This is a serious level of concern.


What is the Problem?


Designated as CVE-2024-30078, we are informed that the attacker doesn’t need physical access to your computer, they just need to be nearby. Once they engage this attack, they can remotely execute code on your device. By infiltrating your device in this way, the attacker can do any of a number of things: install malware, access your data, or use your device to gain entry into your organization’s network, to name but a few.


The vulnerability affects the wi-fi driver, so anyone that uses Wi-Fi on a Microsoft Windows device is at risk. Something to note is that the attack won’t even actively be your fault, since there is nothing for you to click on or download. The worrying thing about this threat is that the attacker can not only attack your device once, but multiple times. Often the attack will go unnoticed and/or undetected.


If you go to public places like coffee shops, libraries, malls, hotels, conferences, or anywhere there are a large number of devices, you could be at risk of unknowingly falling victim to this attack.

What Can I Do?


The best thing you can do is to download Microsoft’s patch, released in June 2024. This should help prevent the problem from occurring.


If you use an older version of the operating system that is no longer supported by Microsoft, the only thing you can practically do is to update your software. If you cannot, or don’t want to, update your software, you might be wise to employ an EDS to alert you to any unusual activity.


As more people learn about this threat, the more potential there is that the bad actors are going to try to use it. If you use Microsoft Windows along with Wi-Fi, this is a real threat and one that should not be taken lightly.

Wi-Fi Myth Series - Myth #8: Wi-Fi 7 Will Fix My Wireless Problems

By Rie Morgan • July 30, 2026
Every new Wi-Fi generation arrives with a wave of excitement: faster speeds; lower latency; more efficient use of the spectrum; and better handling of dense environments. Wi-Fi 7 is no exception. It brings some genuinely impressive technological advances but, unfortunately, it also brings a familiar myth: "If we upgrade to Wi-Fi 7, all of our wireless problems will disappear." If only wireless engineering were that simple. Wi-Fi 7 is an outstanding technology, but it isn't a magic wand. Poor design, interference, bad client behavior, and unrealistic expectations don't suddenly vanish because the APs have a shiny new logo on the box. Let's bust another myth...

Wi-Fi Myth Series - Myth #7: Roaming Problems are Always Client Problems

By Rie Morgan • July 23, 2026
Few phrases trigger a knowing smile from experienced Wi-Fi engineers quite like this one, "It's the client's fault." Someone's video call drops while walking through the office or a warehouse scanner pauses between aisles, voice handsets crackle as users move from one floor to another... then, almost immediately, someone points at the device and confidently declares, "Well... clients decide when to roam." Technically, they're correct. But, practically, that's only part of the story. Roaming is one of the most fascinating aspects of Wi-Fi because it isn't controlled by a single device or a single setting. It's a partnership between the client, the infrastructure, and the RF environment. When that partnership breaks down, blaming one side rarely tells the whole story. Let's bust another myth... Yes, Clients Make the Decision Let's start with the important truth: in almost every Wi-Fi deployment, the client device ultimately decides when to leave one AP and join another. Laptops, smartphones, tablets, barcode scanners, medical devices, and countless IoT products all use their own roaming algorithms. Some roam aggressively whereas some cling to their current AP for far too long. Others seem convinced that losing the connection entirely is preferable to switching. Every Wi-Fi engineer has encountered at least one stubborn client that appears almost “emotionally attached” to a particular AP. :) Client behavior matters, but that's not where the story ends.

Wi-Fi Myth Series – Myth #6: A Site Survey Is Optional

By Rie Morgan • July 17, 2026
Every Wi-Fi engineer has heard some version of it, "Can't we just install the access points where the old ones were?" Or perhaps, "The floorplan looks straightforward. Let's save some time and skip the survey." Occasionally, someone even says the dangerous words, "We've done hundreds of these buildings. They're all basically the same." That's usually the point where experienced wireless engineers quietly smile, knowing that the building is about to teach everyone a valuable lesson because: buildings don't read design guides, concrete doesn't care about your deployment schedule, metal doesn't respect your project budget, and radio waves have never once agreed to cooperate, simply because everyone wanted them to. Let's talk about why a site survey isn't an optional luxury... it's one of the most valuable engineering tools available. Every Building Is Different At first glance, two office buildings may appear identical: same square footage, same number of floors, similar room layouts, yet their wireless behavior can be dramatically different: one may have reinforced concrete walls, another may contain extensive glass partitions, the warehouse may be filled with moving inventory, a hospital may have elevators, imaging equipment, and countless reflective surfaces, a manufacturing facility may contain machinery that wasn't mentioned on any floorplan, and remember: even furniture changes RF behavior! Anyone who has performed enough surveys eventually develops a healthy respect for one simple fact: the building always gets a vote, too!
