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.
It does and it doesn’t.
Any microwave with the door rigged open is a super effective Wi-Fi jammer. Everything coalesced on 2.4GHz instead of licensing their own radio spectrum making absolute mountains of overlap. It’s harder jam nearly everything else. ( Not much harder, software radios are super cheap, but you at least need more electronics knowledge than a screwdriver and tape. )
