It appears to be WiFi deauthentication. Our package came to the front door while we were in the living room (next to the door). My wife was trying to use the echo and it was just not working. This was around 4:45.
Later I received an email saying my package was delivered by Amazon at 4:45.
Although the camera is right at the door, my camera did not pick up the driver pulling up to the house, walking up to the door, placing the package on the steps to take the photo, or walking away. What made me go on my information binge and disregard those “coincidence people” is because the jammer interfered with the Alexa device when we were trying to use it. That was clear signal interference. This has happened in the past, where we would get packages, but nothing was recorded. Of course, we see several posts about coincidences and check your equipment, but let’s get real… if this happened to just only us, then perhaps, but this is happening all over.
The delivery drivers are jamming the 2.4 GHz frequency on the WIFI. The Blink, Arlo, and Ring (most models) use that frequency (see below). The 2.4 GHz spectrum will allow devices to have a longer range when compared to 5 GHz. It makes sense as people may want to spread out the cameras. Of course, the downside is that it is susceptible to these attacks.
Amazon sells the jamming / deauthentication devices:
And you can see how to create them online:
"The use of a phone jammer, GPS blocker, or other signal jamming device designed to intentionally block, jam, or interfere with authorized radio communications is a violation of federal law. There are no exemptions for use within a business, classroom, residence, or vehicle. Local law enforcement agencies do not have independent authority to use jamming equipment; in certain limited exceptions use by Federal law enforcement agencies is authorized in accordance with applicable statutes.
It is also unlawful to advertise, sell, distribute, import, or otherwise market jamming devices to consumers in the United States."
And yes, while WiFi deauthentication is not 100% the same as jamming, it is still treated the same by the FCC. There are real consequences.
PLEASE, let’s start reporting these incidents to the FCC and hold Amazon accountable as well as the drivers accountable.
*While we do have a real security system, it still bothers me that people are circumventing the system (illegally) and coming on my property. I do like my ring doorbell and other cameras, however, I will be gradually replacing them with PoE cameras as well as adding more cameras that work directly with my real security system.
