- vuln 8y agoSell 'mobile' Faraday cages one for every squad car... Profit?

- MisterTea 8y agoAnd people called my hats crazy...
- vuln 8y ago[1] + this kind of pouch. Probably could sell them for at least 100$ a piece.

- klodolph 8y agoIt would be hard to sell it for $100 if you can buy digital evidence bags for a couple bucks: https://www.arrowheadforensics.com/products/evidence-packaging/faraday-pouches-bags/cell-phone-faraday-storage-kit.html https://www.arrowheadforensics.com/products/evidence-packagi...
- TeMPOraL 8y agoPut a "5G-ready!" sticker on it, and you're back in business.
- toomanybeersies 8y agoJust use a chip packet instead? https://www.telegraph.co.uk/news/2017/11/27/australian-sacked-skipping-work-using-crisp-packet-hide-whereabouts/ https://www.telegraph.co.uk/news/2017/11/27/australian-sacke...
- mikeash 8y agoThe FBI has been doing this for some years now. There was an amusing story a while back about how Verizon put a new cell on top of the building where the FBI had their special shielded room, and the signal was so strong it was able to penetrate the shielding and some phones were lost. I could only find this brief mention here: https://spectrum.ieee.org/tech-talk/telecom/wireless/when-the-evidence-is-on-the-cell-phone https://spectrum.ieee.org/tech-talk/telecom/wireless/when-th...
- squarefoot 8y agoOne possible countermeasure: detect the lack of any electromagnetic field paired with no vibrations at all and colder temperature, ergo the phone isn't in someone's pocket in a no reception area but very likely was put in a shielded box. Phone sensors can reveal a lot of what is happening around them.
- chii 8y agoAnd everytime you put the phone in a safe, it gets wiped...
- gambiting 8y agoOr if you go hiking in the middle of nowhere with no signal, the phone wipes itself. Very useful thanks.
- Dylan16807 8y agoThat is not what the post says, thanks.
- gambiting 8y agoHow is it not? "detect the lack of any electromagnetic field paired with no vibrations at all and colder temperature" You go hiking far outside of civilization and go to sleep in a tent, there are no electromagnetic fields around you at all(that the phone can detect anyway), there are no vibrations at all, and the temperature is cold because the phone is not on your body. Or for a slightly more realistic example - I stayed with a friend recently who lives in a house from the 12th century - walls in there are about a meter thick, in certain rooms there is absolutely zero reception from any network, wifi doesn't penetrate at all. The no vibrations and low temperature points also apply there. What am I missing that the post apparently said?
- jki275 8y agoHe's suggesting some sensor checks, not giving a total framework to account for every edge case. If you were to implement something like this, you would take many cases, including edge cases, into account.
- onetimemanytime 8y agoCan they just take them offline? Or...at do they at some point need to be online for the evidence gathering? I wonder how can they prove that she did it? Or it's your phone, you know the password and let's try to convict you? If it was programmed to be erased before the phone was taken /crime committed she is not guilty I guess.
- rv-de 8y agoWith regards to the scene from "Snowden" where he places the phones in a micro wave oven. I was surprised to find that this doesn't work - at least not with my grandma's oven.
- bigzyg33k 8y agoThat's interesting - the microwave should insulate against them or it might be unsafe
