SAN JOSE, Calif. (KGO) -- This riddle starts much like numerous others, manifesting in the darkness of the night.
It originated on the front porch of Jim Grubb's dwelling in San Jose, when the barking of his dog interrupted his sleep.
He indicates that after waking, they went downstairs, found the front door slightly ajar, and thought to themselves, "It appears we must have forgotten to close the door last night."
The subsequent morning unveiled new evidence. Grubb identified missing items, which included a laptop and a drone.
He indicated, "I looked at the Nest video camera mounted at our front entrance. The footage captured the burglar in the front yard, showcasing a flashlight, and at intervals, his beanie cap was discernible."
He states further, "...and while I am watching the video, I start to see these gaps emerging, and I note that I have a significant number of gaps."
The video includes gaps where it is possible we could have made out the thief's identity.
Jim contacted Nest customer support and was informed that the video doorbell had been functioning without any communication interference with the router until the incident transpired.
He conveyed, "I could hardly believe what I was hearing. Consequently, I began to research the topic and found that one can buy a tiny microcontroller. This device is capable of de-authorizing clients connected to your Wi-Fi network, which leads to interference."
The items are available at a cost of $7. Grubb has come across a wrist model priced at $50 that provides more refined control. He acknowledges that he lacks proof, yet he is worried that thieves may be interfering with Wi-Fi communications.
Google has communicated its uncertainty to 7 On Your Side, noting: "Google Nest is devoted to ensuring the privacy and security of our customers. We recognize a specific issue with the Nest Hello Doorbell, and our team is actively conducting an investigation... there is no indication that the device was intentionally tampered with."
Based in Wales, Tristan Perry is a technology blogger who has been reflecting on this issue for a while and believes that it is not especially surprising.
It is commonly accepted that Wi-Fi may suffer from various issues, such as problems with mobile devices, disruptions in Zoom calls, or pauses in Netflix streaming, as he articulated to 7 On Your Side.
The advent of advanced theft techniques has raised concerns regarding the reliability of traditional security systems, including surveillance cameras and burglar alarms. Thieves are now utilizing tactics to interfere with Wi-Fi signals, which can diminish the effectiveness of these protective measures. Police advise that residents consider implementing additional security strategies to prevent victimization by thieves.
Most current homes are reliant on Wi-Fi signals for the effective functioning of security system burglar alarms and surveillance equipment, which includes doorbell cameras.
Law enforcement suggests that residents opt for wired connections instead of Wi-Fi for their surveillance systems. They recommend contacting network providers or electricians to connect the burglar alarm system to the router using cables. This change removes the requirement for Wi-Fi, effectively preventing the operation of Wi-Fi jammers.
The FCC reminds the general public that in cases of home Wi-Fi interruptions, it is advisable to contact the service provider as soon as possible. This will clarify whether the disruption is due to a device failure or if it is being caused by someone using a signal jammers to interfere with the signal.
VERMILIAN PARISH, La. ( KLFY ) — Authorities are asking for the public’s help in identifying a man who posed as a cable installer and attempted to break into a Vermilion Parish home.
The Vermilion Parish Sheriff’s Office says a man (pictured below) driving a white SUV attempted to break into a home on Red Rose Lane near Louisiana Highway 338 on Tuesday. Officers say he posed as a cable or security camera installer and used a suspected Wi-Fi jammer while trying to pick the front door lock.
Anyone with information about this incident is asked to contact Sheriff Chad Touchet at 337-898-4403.
- As technology becomes cheaper and more accessible, smart security systems become vulnerable
A review of news reports of burglaries in which Wi-Fi jammers were used reveals plenty of prior evidence of such behavior. Back in January 2020, a post on the Ring community reported that one of the company's wireless doorbells missed a porch thief after being hit by a Wi-Fi deauthentication attack. In 2021, 2022, and 2023, it was also easy to find reports of burglars using Wi-Fi jamming techniques - with reports becoming more frequent as time went on.
We mentioned Ring as one of the companies promoting video doorbells to solve multiple home security problems, but other wireless smart home security products from Blink (Amazon) and Nest (Google) are also susceptible to wireless signal interference. Worryingly, by 2024, Wi-Fi jamming will be almost a piece of cake for would-be thieves. Jammers can be purchased online very easily and cheaply, with prices ranging from $40 to $1,000. jammer device are not legal in the United States, but are readily available online.
For those evaluating the effectiveness of a wireless component home security system, several recommendations can be advantageous. First, create a physical connection that supports wired functionality and enables local storage of recorded footage. Additionally, utilize smart home technology to simulate the presence of occupants in your home. It is also advisable to check if your device can provide alerts in the event of a lost signal or connection, and to consider adjusting these settings for improved security.
In the city of Edina, Minnesota, a serial burglar has been accused of employing a Wi-Fi jammer to disable security cameras connected to the internet before making off with victims' valuables. Although Minnesota is not widely recognized as a leader in technology, it is not unexpected that there have been instances of burglaries assisted by Wi-Fi jammers reported in the U.S. over the years. This situation illustrates that even those engaged in criminal behavior are utilizing technology, which should encourage homeowners to consider implementing effective security strategies.
It is suspected by the Edina police that nine burglaries of homes in the last six months were perpetrated with the use of Wi-Fi jammers, which would have obstructed investigators from gathering video evidence of the crimes.
The thieves’ modus operandi is believed to be:
Jammers serve to confuse wireless devices instead of fully blocking signals. They often cannot manage to transmit legitimate traffic as a result of overwhelming the wireless traffic.
