Ok so if you don't already know, the Faraday Bags do NOT (almost always) prevent a turned on cell phone from recieving/sending calls and/or text messages and this is becoming a problem for us. What are you or your company doing currently doing to prevent these phones from getting a connection and analyze the phone?
(Keep in mind "best practices" ideally involving us NOT changing ANY data, thus placing the phone in airport or standalone mode is not a solution).

Thanks for the help

With the bag that came with Neutrio - I've never had a connection, provided the bad is plugged into the neutrion box. we have a cell tower nearby. Some people choose the lab location accordingly. don't power on the phone if it's off until you have it in the bag/lab. powering on will change some data. if a phone is on things will change there as well.
The goal is to limit things and the way to do so is by blocking the signal.
Make sure you have the PIN for the phone / SIM if there's one as breaking it later might be hard.

A lot of effort went into the design of the Neutrino bags - even the Velcro lock acts as part of the cage. Great engineering, steep price. PS the software is reviewed to be *not* as high caliber. But if you need an excellent Faraday cage, I'm sure GSI will sell you a bag separately if you call sales.

Do you have an estimated cost for the "cheapest" working cellphone blocker/bag? And what is it called?

I find the SIMID Cloner works perfectly, the only down side is you do have to remove the back of the phone and most often the battery too to accomplish this. I have found signal blockers highly effective but they are seriously illegal and I cannot condone the buying of such equipment )

You could use a faraday box. This works well. In the UK they are supplied by dataduplication however I believe they are sourced from the US.

Also, the SIMID cloner from .XRY/Aceso/CelleBrite is a suitable solution.

Don't forget that it is I believe near impossible to analyse a lot of mobile phones without changing something. Most of the things which change cannot be acknowledged as they are not visible using the menus on the handset. For example parameters of the SYNCML or ACTIVESYNC servers on the device. (depending on type).

Taking thorough notes and having a good understanding will be useful later in court.

have you tried the Phone-Shield bag?

www.faradaybag.com

There is a video on the home page showing them working.

Coligulus,

I've heard the the Faraday Box is often expensive for LE. Do you know the cost range?

Simon,

Though it shows on the websites that the Faraday bags work, unforunately 99% of the time they do not.

Hi Simon,

I believe it cost us around $1500 + shipping. Expensive yes, but so far I believe it hasn't failed us yet.

I do believe it is the box which paraben retail now I've had more time to think about it.

I agree that the bags are not always reliable however if cost is an issue then it's either a bag or a cloned SIM card should it be a GSM handset.

I dont think you have used one of mine? I have heard this about another version, (single ply, no window), whereas mine, quadply, another faraday material in the middle and a window allowing you to see whats on the screen and photograph it do work.

Try one out.

Regards,

Simon
