Wi-Fi jamming attacks are on the rise. How they affect your smart home security

With more than a third of North American homes protected by a video doorbell or some other Wi-Fi-dependent device, it’s reasonable to worry about the growing threat of Wi-Fi jammers. These mysterious devices can override your smart home security monitoring, effectively neutralizing the systems you’ve relied on for peace of mind.

Indeed, these increasingly cheap and accessible jamming devices make it easier than ever for criminals to block your security system’s primary communications signal.

Just something else to consider while living in Biden’s America.

Not surprised

They’re going to need a few layers of body armor to affect my home security.

I like everything wired, PCs, laptops, security cameras.

The entire high tech and telecommunications industry is at risk here. If current systems are useless, then they will lose a lot of business.

How about a mandatory 15 year jail sentence in addition to the sentence for an underlying crime for any use of a jamming device in the commission of a crime. I was an amateur radio operator years ago. I think operating without a license was already a serious crime against the FCC.

Yep. For every measure there will eventually be a countermeasure.

But, but...jammers are illegal in America!

Google the term Wifi Jammer, they can be purchased from Amazon and jammers can be purchased to jam not only Wifi but any other signal including Blue Tooth.

I’ve watched video on how to create a device to open car door, in some cases you could even start the car.

Basically, any device that emits an electronic signal, can be jammed, duplicated or retransmitted and used for exploitation.

It should be illegal to build, sell, or possess this as it has only one real purpose, committing crime. The same for cell phone jammers. But, unfortunately, people will make excuses for them until they are personally the victim of one.

[Reno89519]

The was a few articles, at least one posted on FR if I recall correctly, that reported how these were being used, maybe in Memphis, to break into and steal cars. Pretty much defeats your security system. Haven’t read how national this problem is but I suspect anything secured electronically, especially wireless, is at increasing risk.

My home security system can easily be defeated with a single slice of bacon.

Yes technology has a evil twin as well as most things.

[DEPcom]

Need to set up an Arduino to detect Wi-Fi jamming and set off a house alarm when detected.

void checkWiFiStatus() {
if (WiFi.status() != WL_CONNECTED) {
Serial.println(”WiFi Disconnected! Possible jamming detected.”);
digitalWrite(buzzerPin, HIGH);
digitalWrite(ledPin, HIGH); // Optional
} else {
digitalWrite(buzzerPin, LOW);
digitalWrite(ledPin, LOW); // Optional
}
}

First, you would have to make the ban worldwide. Impossible. Second, an effective jammer may only be a regular existing electronic device with trivial modifications. Third, some motorized devices are natural jammers, depending on the frequency. Fourth, jammers might have legitimate uses (e.g. stopping certain kinds of electronic activity in detonation zones, military bases)

MY SMART HOME SECURITY WEIGHS 85 # & NOTHING GETS PAST HIM.

[ridesthemiles]

MINE can count——

Demands 3 ‘bone’ treats

1 is NOT 3

2 are not 3

3 is 3

Then he quits bothering you.

BUT he can be CUJO if he doesn’t know you & an 85# pest if he does like you.

I hope you’re talking about a dog and not your grandson.

Can’t fool working line GSD or Corsos.

homes protected by a video doorbell

++++++++++++

Cameras do not ‘protect’ anything.

google the term stolen cars tiktok challenge.

Awhile back, someone put out a video on Tiktok about how to steal Kia and Hyundai cars, immediately afterwards, there was a huge spike in those models getting stolen.

Just think, you key fob puts out an signal to lock/unlock your care and in some models with push button starting.

I’m not up to speed on how car companies are trying to counter this trend, I’ve read something about frequency hopping systems that are constantly changing their broadcast frequency making it more difficult to reproduce or jam.
