If you're going to be a reporter and also an insurrectionist against the government, I would expect the FBI to pay more attention to the latter than the former.

Like right wing dingdongs love to say, "if you can't do the time, don't do the crime". Hadn't heard of this dude until today, but now I'm looking forward to seeing him sentenced and jailed.

That is... a lot of paper...

Like, 30-40 cases...
so basically 2 pallets of ... paper.this was not a coincidence.

Not to mention knowing just where to drill the hole in the concrete wall, and what channel to jam for the wifi alarms and such. (Locals had been having wifi trouble all weekend.)

An inside job for sure.
 
Wi-fi jammers have been available on the grey market for 20 years. That doesn't surprise me. Knowing where to drill is hyper specialised info, it also requires power maps etc to be known. It is all fun and games til you pop the main breaker and take out the power for the whole neighborhood. Yeah, inside or super heavily researched. I saw an commentary on this with the talking head going on about "it would require multiple large trucks" Nope... Every professional in the industry knows 2 facts. The thing most likely used was a work truck and a guy in a nicer vehicle holding a clipboard (them pesky clipboards are like cloaking devices) or a few mini vans. White mini vans are the thing least noticed by.... well everybody, every company that is looking for vehicles and don't know what they are doing invests in them. Then finds out they are *NOT* trucks, just cars with boxes on top. Pesky devils are a logistics nightmare, but are nearly as good a cloaking device as a clipboard.
 
If it's the old 2.4ghz wifi, everybody already has a powerful one in their kitchen, if they just defeat the door interlocks. ;)
 
I'm old.
I Remember when an old chugging along tractor came down the road and grandma's TV and radio went all static - buzz !!!
Copper wires I know, negative ground I know, can that JAM modern electronics TOO?
You know better but I wonder if such a spark can be a jammer.

Well yeah, and the added benefit is melting the candy bars in your pocket...

There are 3 ways to go about defeating wireless systems (not just wifi, rf in general) flood over ride, in other words you can put out so much noise the signal is lost in the mix (like the old tractor, probably had an old uhm.. not alternator.. Generator thing, sorry brain is still jello from my weekend)

The 2nd way is simple, burn the finals, if you know where the receiver is, get a moderately large source (high power) and get physically close to the receiver, point the (hopefully directional) antenna at the receiver antenna and fire it off, keep it running as long as possible. Only the very best of units will handle this, and those will require the case being opened and fused systems or gear bridged circuits replaced.
(this is how Germany attempted to take out british radar units on the land, but they tried crossing "open fields" which were in use as a deployment group departure point)

and lastly, the one near and dear to the hearts of all the IT guys who were around for it. Cisco systems in the oughties put out a meshed system that was "built for the cluttered environment of cities and large buildings" in other words, it was going to use intelligent channel switching. Which most the other companies already did. In order to make it more competitive, it would latch the signals of other "competing" units and then flood those channels, it would then "train" the surrounding "smart' managers to stay off the channels that the cisco unit wanted to use. Which was great, and it of course violates every countries laws about use of the RF spectrum. The US is pretty restrictive, but *ALL* countries have rules about aggressively attacking things, that is reserved for government entities. This system was quickly recalled and replaced, The problem that existed is that the latching/flooding system was not in the controller, it was an add-on circuit in the transceivers. So all those old cisco units out there have that circuit as a snap in... of course I am not suggesting anything.

SO rumour has it that the latch and scramble systems that appeared on the grey market around 2010 might in fact have been either knock off of the cisco circuit, or are in fact just ones pulled from the trash bin at Cisco....

Latch and scramble is the holy grail of how to mess up your neighbors, as a circuit goes it is not hard to design, as an implementation goes, it is a bloody nightmare to get them tuned in. the best use is to get badly tuned ones, pair them into groups and then just let them detonate the spectrum in their area. Add to this a directional antenna with a 2-3kw linear amplifier on it, pop it into the top of a truck with a tilt over camper shell and you have a mobile denial system.

:;looks around:: what? It is talked about in the industry. I never did it... well, not with civilian hardware.

....microwaves are 2.45GHz. λ = 12. 23 cm

Not 2.4GHz.

A 2.4GHz signal is 12.5cm.
 
With enough power, it really doesn't matter, the lack of good isolation on the emitter actually helps.

If you ever set up a spark gap experiment, you can "hear" the pop on an am radio up to a thousand yards away.. no matter what size poles are on your emitter.

A great example, there is this chap, lets call him Dan.

Dan had a really expensive hobby, it was called University, and to afford University he had already sold off his future, so since there were no takers on most the things he was good at, he went ahead and started building linear amplifiers in the 1 to 1.7Kw range, the reason for this being what he built, Motorola helpfully had the entier spec and build plan in their release info. . These sold for between 4 and 1200 bucks Depending on the wealth of the buyer, they cost about 65-75 bucks to make. His best sales reference was get someone who had a car (he was poor remember) and meet the possible buyer at a fast food place. While negotiating things, he would show "proof" of the power of the system, just key up your CB, it is an AM system and at 1.5kw within a few dozen feet of the speaker wires, the wires were enough to pic up the signal and the voice would come out of the speakers.. without any connections.

Hence the whole "Taco Bell has Cheese Worms" event was born...

Or so the rumour goes.
 
Regardless of their specific base frequency, they can put out enough garbage in the general band to screw up 2.4ghz wifi (and other devices in the band), even in normal usage, when they dont' seal well. If they were emitting all their energy outside the cooking chamber, I imagine they'd swamp actual signals fairly thoroughly, especially given the total power output they have vs that of the typical signal transmitters in these other devices.

Not something I would want to test myself.


(way back 3-decades-plus ago when I still did ham radio (where's that shaking old guy smiley?) , there were plenty of things that shouldn't, by the base numbers, interfere with each other...but definitely did)
 
I only had a technicians license, never wanted to talk to people, just play with the toys.

It makes sense, if you have issues with cheap power supplies giving garbage messy signal, think about it rough off a winding with literally no concern if it is dirty, just needs to put watts to water.

I had to be careful when working on peoples gear back in the day, my lil shed in the back of the house was close to the antenna pole, well, like 50 feet, but had line of site. Bob liked watching Dr Who on the PBS out of Petaluma, so it was a bit of a trash signal by the time it got to our lil ghetto. If I did not have the full Faraday clothe up, it would just destroy the reception. Mainly from me always playing with yep, messy multi Kw signals...

I finally got an oscillascope, old Tube type HP unit... When I saw what I had to do to clean up the messy signal, I was shocked i had ever done it.. then I scoped one of my older units.. shouldn't have been shocked, signal was garbage... Ended up doing a ghetto recall had dozens of truck drivers showing up to get their units swapped out. I could not just let that mess go...

Snip....
According to the police log, the LAPD responded to 13 alarm calls at the building in the year prior to the heist, and all of them were determined to be false alarms. Notably, one occurred just before 11:30 p.m. on March 30, the night before the heist. A patrol car arrived at the warehouse minutes later and deemed it a false alarm.

Another alarm rang at the building on at 4:36 a.m. on Easter, according to the log. Hours later, the log shows, a police car was dispatched to the property, a supervisor was notified and a report was written. The log does not indicate what the police found. However, a resident at the neighboring Tahitian Mobile Home Park previously told The Times that FBI agents visited her the day after the burglary and asked if she “saw or heard anything suspicious around 4 a.m.” on Easter. (The woman said she was asleep at the time and did not.)


At 7.22 a.m., another alarm rang at GardaWorld’s warehouse and a police car responded about 45 minutes later; the LAPD log shows it was considered a “valid alarm.” Finally, an alarm rang at 3:51 p.m. and a police car arrived around 4 p.m. in response. This was deemed a false alarm, according to the log, the details of which were first reported by TMZ.

According to Aria Kozak, chief executive of L.A.-based security services company Elite Interactive Solutions, the false alarms triggered before the heist could have been the result of criminals testing the security apparatus at the building.

“In that particular case, the false alarms could just be a little window into the criminal activity,” he said. “They are very capable and smart and they will look for the soft or weak spot.”...snip

"Snip...."

Hard to track backwards - Noun'?
& Read between the lines:
What If the power was out only intermittently (it's low voltage ) to surrounding selected security systems various apparatus by technicians & (eliminating clues )
+ crude jamming & ( wiping out record )
+ created diversions leading around the whole town both physical and electronic large and small &+ real and virtual &+ here and there
all choreographed in rapid succession it is Holly wood ( goose chases still unknown )

It reminds me of a huge theft - in volume not { BIG $$$$ } Thieves stole the complete inventory of colchester power equipment John Deere tractors one night after the small town had a planned power outage and the dealer - MINUS one uninterruptible power source for the security system + all personnel at a party + one conspiracy = a big three truckload (two trips) Green and Gold unsolved mystery
