This video couldn't have better timing. I had some left over breadboard I was gonna give away but now I found something interesting to do with them! Thanks!

[@fixer0deyz576]

I have learned many things in this channel This channel is really awesome

[@graemepinnock]

Hi Kody, technically resistors are required, not because you may have a "fragile LED" but because the current needs to be limited to prevent either the LED burning out, or worse, damaging the ESP8266. It's worth noting that not all RGB LEDs are common cathode like yours, some are common anode, and viewers should make sure they buy the correct one if building this circuit. Finally, it sounds like you are saying "Ardreeno", I think it's pronounced "Ardweeno". That said, keep up the vids, I do find them useful and educational. Thank you

[@NullByteWHT]

Thank you! The correct wiring is in the full guide, I'll make sure to note this in the next guide.

[@hexernightcore]

Thanks for showing my request . Love ur channel ;-)

[@mocromo2010]

I'm learning so much, thanks!

[@joaofreitas3504]

Great video! Is nice to see Ethical Hackers and Security part of the community to also use simple eletronics to solve and do some useful devices. The device is simple but I do think that you code is a bit messy! But there's a good job here congratulations. Im an Eletronics Technician and I'm going to course Eletronics Engineering, the next step is add an I2C 16x2 LCD screen so we don't relly on a computer to see the results in the monitor. I'm trying to get some knowledge about security. Thanks for all the knowledge! Regards from Portugal!

[@NullByteWHT]

I cleaned up the code a bit for the full guide here: gitlab.com/skickar/NodeMCUWiFiLinkMonitor/blob/master/WiFiMonitorNodeMCU.ino Thanks for watching!

[@Dave-kq7gv]

you have the coolest vids!

[@ujjvalw2684]

Spacehun did a great job!

[@lesliemitchell1621]

Thanks your video helped me understand how my WIFI is being jammed

[@sladewilson9122]

Cool tutorial. You should make tutorials on MITM attacks also because the old MITM attacks aren't working.

[@-someone-.]

Thank you once again...😇

[@vibheeshavelayudha1903]

U have really good content, but the reason ur channel hasn't grown is due to its name, people search hacking or hacker in KZbin which pops up shit content but u guys have potential knowledge for many people who are unaware of it

[@elishaisarinde6462]

Pls can you drop a link where one can buy all those external network adapter you used for one of your video: Ethical hacking with Raspberry pi B+

[@GalacticTechTrails]

Thank you

[@jasonmadruga9028]

I've already got an old Raspberry Pi. Any way to use it to detect wifi jamming or other attacks? I've already got my network in WPA2 with Protected Management Frames required all my devices are working.

[@nicolaihier2522]

Arduino has pull-up and pull-down resistors build into the board (look if NodeMUC has one too and you can use the function INPUT_PULLUP or INPUT_PULLDOWN). Then you don't have to use resistors on led's. 2. you could use one resistor from ground (on the led) to the NodeMCU (GND) because you are still limitting the resistance.

[@ModernRetroRider]

It works, but how to how to hide the default SSID of ESP?. sorry I am very new to this one.

[@juanramirez-th6mb]

Bro how can i get a hold of you ive suspect my nieghbhors are are monitoring me with wireless an wired devices. I could trully use your advice

[@Droggelbecherbot]

Aren't the resistors just bypassed if they are in the same row? Or did I not see this correctly, kinda hard to tell in the video...

[@brandoncejacruz218]

Yes, I think they are in the same row haha :c , you can also tell by the LED intensity not decreasing

[@NullByteWHT]

The correct layout for using the resistors is in the guide, but during the demo I forgot to plug it onto the other side.

[@Droggelbecherbot]

I'm happy to see that I'm not the only electronics noob :D The first time I started experimenting with an arduino there was smoke rising from it...

[@NullByteWHT]

@@Droggelbecherbot I too have released the magic smoke from a nodemcu already once

[@miry2510]

It's not bypassed, depending if you put it in serial or parallel in a circuit it modifies either the current or the voltage. Putting a resistor in serial will affect the voltage, and if you put it in a parallel connection it will affect the current.

[@IdeaSearch]

Is it possible to make GSM / GPS jammer detector ?

[@GLITCH_-.-]

But this isn't detecting Wi-Fi jamming or any sort of attack. It is just indicating if it can connect or not. Put something in between it and the router, like distance or a metal cage, and it will "detect Wi-Fi jamming". See the issue? *_This is like saying that a desk lamp is a power outage/surge detector._* I assumed this to be a how-to to setup a listening(monitoring) device that detects the actual jamming packets. Instead it's a small "desk lamp" that spams my router log.

[@threepoint1434]

Could you help me with something I think is weird? OK so ever now and then, I opened cmd, I typed NET VIEW and all the computers that were on at the time showed up. But now when I do the same thing, one computer is not showing up?! Could that mean it's hacked, or somthing?!

[@erickrauss4006]

Can you save its report in say nano? so if your wifi was hacked or jammed but you did not see the light change (coffee brake). You can still see when it happen and howlong it lasted for.

[@m4gg197]

Maybe a Raspberry Pi Zero that is capturing with tshark (Command line tool for Wireshark) only detecting deauth packages? Edit: you could still use a rgb led to indicate the status while not coffee breaking 🥴

[@botiolle7451]

The resistors won't do anything when connected to the same row!

[@NullByteWHT]

This is true, I added a note to check the full guide for the right wiring

[@Yufflez]

I thought I saw that but didn’t see anyone else comment, I was going to comment that he did his resistor wrong… lol

[@himanshukandwal8710]

Hey null byte are you using Semicode OS?? Nice tutorial btw😊 My windows 10 and kali Linux both aren't detecting my wifi adapter what to do buddy?? I have been facing this for 3-4 days..I dont know what happened how it happened, windows 10 detects it sometimes but it doesn't work..and if i check network devices in my device manger its not there..so is it hardware problem ? My adapter is mot connected/attached properly to motherboard etc.... Thank you😉

[@m4gg197]

You are using a pc? Then simply google for the data sheet or find the manual. There you can find the pins for the USB connectors. Simply shake them a little bit and tighten them.

[@rockyhellboa]

Hey man please make video on pmkid

[@rzxv3]

I might use this to my advantage I will configure my router to only use Ethernet so I can plug in a node mcu and make the antenna strong when deauth hits the WiFi it automatically turns off

[@classicalfunfacts2842]

OS?

[@vociferousrich3316]

Firstly, i absolutely love your channel. Ive been in IT and Telecoms for about 9 years but have only just decided to get into Cyber Security. ( i should of done it sooner tbh). Anyway!!! I have a question. Do i need a Linux Machine to Ethically hack? Or can i do all of this from my Windows 10 machine? thanx Kody, keep up the fantastic work dude. all the best. Rich

[@javierpallalorden]

It would be better and smarter if you would blink the red led in case a lot of deauthent packages are send.

pls bro dont ignore make linux mint turotial

[@tjs200]

So can I has hacks? I need hacks plz

[@NullByteWHT]

Everyone but you gets one

[@jeremy9100]

This seems like it detects connectivity issues more than jamming. Unless I'm thinking about this wrong it's going to blink red regardless of the reason you aren't connected..

[@javierpallalorden]

Jeremy, yes that is the reason that this is not a good method, you should check for frequently send de-authent packages instead.

[@jeremy9100]

@@javierpallalorden even that doesn't cover all aspects of jamming 802.11... You could flood the channels, death, disassociate, or do other things depending on the config. The concepts cool it just leaves a lot to be desired and a lot of false positives.

[@javierpallalorden]

Okay, but the deauthentication frame is one thing you can easily check with a display filter. Deauthentication --> wlan.fc.type_subtype==12

[@kelvinclark5888]

Yeh but he doesn't do that... re just verify the link.

[@jeremy9100]

Yeah, its a good concept and a decent starting point but the concept isn't fully developed. You almost need to monitor the 2.4 ghz band for saturation, look for deauth and disassociation frames, is the AP alive and check your systems interface state is ifup/ifdown?

[@root317]

Nice but as you sayed this can be tricked. If you attack a specific device (deauth) it wont detect anything... but hey its easy and will work on most cases :)

[@m4gg197]

Choosing a Raspberry Pi zero is also a good choice: simply write a script that will start on every boot and that captures only deauth packages with tshark and that indicates with the LED whether there are deauth packages or not flying around in maybe the last 10 seconds. Additionally you also could save the output in a file so that when you are away you can identify an attack even though you saw no LED blinking.

[@sheerazali2395]

Hey make a video about Bluetooth hacking

[@m4gg197]

You can’t hack devices via Bluetooth. You can only discover their MAC address.

[@stacyhoff9287]

0:36 awkward:/

[@vijaymadipally2608]

No dude, You didn't wire up the resistors correctly. They shouldn't be in the same row. if so then the rows are already short circuited and there is no point of having a resistor in the same row to limit the current flow.

[@slickpapaj]

He missed it in the demo but the guide has the correct way.

[@NullByteWHT]

This is true, I added a note to check the full guide for the right wiring

[@vijaymadipally2608]

@@NullByteWHT yeah, I noticed that you have wired up the resistors correctly in the guide. kudos for your video.

[@veryfrozen3271]

You could achive this by downloading a jammer detector on your phone
