The Los Angeles Police Department has warned residents to be wary of thieves using technology to break into homes undetected. High-tech burglars have apparently knocked out their victims’ wireless cameras and alarms in the Los Angeles Wilshire-area neighborhoods before getting away with swag bags full of valuables. An LAPD social media post highlights the Wi-Fi jammer-supported burglaries and provides a helpful checklist of precautions residents can take.
Criminals can easily find the hardware for Wi-Fi jamming online. It can also be cheap, with prices starting from $40. However, jammers are illegal to use in the U.S.
We have previously reported on Wi-Fi jammer-assisted burglaries in Edina, Minnesota. Criminals deployed Wi-Fi jammer(s) to ensure homeowners weren’t alerted of intrusions and that incriminating video evidence wasn’t available to investigators.
That’s a relatively sophisticated attack though, and like you said is dependent on versions of WPA. It’s easier from a hardware perspective but more complicated software.
A 2.4 and 5ghz jammer is just simpler. Turn it on, everything fails. Even stuff that doesn’t talk Wi-Fi like Zigbee. Throw 400 and 900mhz on there too and now even residential security sistems will be frozen. It’s just simpler to use brute force for something like this.
