Tech News Alert from Helpful Dave!
There is a new dangerous exploit that is in MILLIONS of routers!
Your router may be vulnerable but you can test it for free using the link I provided below!

---What's the News?---
Lets break it down in a broad, very simple, and non-technical way. We’ll start with the famous quote “Why re-invent the wheel”. This is how a lot of internet appliances manufacturers operate. Manufacturers who make routers, wifi-outlets, wifi-switches, etc. don’t create everything about the product from scratch.
Try to think about it like a car. The engine, the wheels, and the brakes for example all have the same underlying technology as every other car on the road. These are all publicly available technologies that nobody really owns.
Manufacturers take and borrow from free code libraries that are kind of similar to parts on your car. In my opinion there is nothing wrong with this. The free code libraries are “Open Source” . This means they have multiple people reviewing them and since the code is public anyone can fix it if they find a problem.
Think about the people who review open source code libraries as mechanics!
The problem comes in when a vulnerability is found and your Manufacturer does NOT update they product you purchased from them! Then your Internet Appliance is vulnerable to the exploit and someone more nefarious can use it to harm you and anyone who shares your network!
This has become such a large problem that the FTC has even started warning companies that if they do NOT update products or at least inform consumers that their product will not receiving an update they may face fines.
That’s what is happening right now there is a big library (Kcode library specifically) that a lot of manufactures have been borrowing for years! So there’s a good enough chance that your router may be vulnerable.
So please go to this link and test yourself! https://www.grc.com/x/portprobe=20005
The best result is “Stealth” that means that your router isn’t replying to the request at all so you’re practically invisible to anyone looking to exploit this vulnerability.
If you are vulnerable you should try to update your router’s firmware or see if you can close port 20005 in your router’s configuration screen.
That’s all for now! Please feel free to let me know if you have any questions or comments or want more information.
