Faraday Bags don't work.. what do you do?

I have been using one of Simon's bags for around a year now and, touch wood, it has been OK every time. I also have a bag that was 1/2 the price and it's pants.

What a top chap! Thanks for the kind words.

This is a really old post so I hope for a reply / assistance.
I Use aluminum foil for purposes of transport if the phone is on the drawback is no view.

Would there be sugestions with regard to the creation of a faraday cage that some one has tested.
Considering the dollar is nearly worth 10 times the local currency.

Jack1809,

I understand the problem of the Rand versus the Pound, but if you want a version that works, take a look at faradaybag.com there is a video there that shows you how it works.

Best regards,

Simon

(Keep in mind "best practices" ideally involving us NOT changing ANY data,

What about the data that is altered when placed in one of these bags? (a proper working one that is)
Broadcast channel, TMSI,and other automated data ie real evidence would all be lost, to save possibly the date time? which is non automated

And the risk of automated scripts/processes running on the handset - for example Symbian event log (and therefore call log) longevity setting.

With Symbian handsets it can actually be more prudent to go out of your way to lose the date and time settings by letting the internal battery run down - the event log can have all sorts of juicey stuff in it the time and date are boring!

If you haven't seen them yet, there's a new line of faraday bags available for forensics investigators and military. MOS Equipment built the Mission Darkness Faraday Bags line to accomplish a few goals.

1) Offer incredible shielding for current and 5th generation devices. This means top of the line faraday fabric and dual paired seam sewing techniques.

2) Allow agencies to add their agency/department/staff information without having to silkscreen each bag. There is a closable business-card size pocket on every bag. Place a business card inside, or slap a more permanent sticker on the plastic to brand the bag.

3) Assist with asset tracking. Every bag has a unique serial number to track where they end up.

4) Other features. For example, the Mission Darkness X2 faraday duffel bag has a removable front faraday pocket with molle straps. Federal, tactical, and military teams can remove that pocket and place it on any molle pack. It allows for separation of evidence and flexibility. https://mosequipment.com/products/mission-darkness-double-duffel-faraday-bag

MOS Equipment has more sizes available and other options coming in the future. In the meantime, please offer any useful comments that can help us understand what the forensic community would like to see.

Thank you,

I am quoting the whole post just to have a trace remaining (when and if - like he did with all his previous posts 😯 - rjudy55 will edit it to remove its contents).

@rjudy55
Any documentation, technical specs. laboratory testing, and similar? ?

I debated doing that and there's a few reasons I did.
- A lot of the information was old and applied to the products I was working on at that time, but those products have since changed. Essentially a lot of the info was outdated.
- This is my personal account, and those were related to a previous employer.
- If someone read through all of the comments and saw my old vs. new it would just be confusing.

Overall this is a pretty old thread and wasn't active. I figured I'd stir it up a little and get it active again. Thanks for copying my comments though, I guess now it's out there forever )

On your question - we have test point specs for cell and WiFi frequencies, as well as real world testing in various environments. But these days we've just reduced it to a single spec like, "Average 70dB attenuation" because our customers don't equate a spec to "this bag will work" or "this bag won't work" anyway. They always want to get a sample and test it for themselves. It's easier to get a general idea of shielding from an average specification. A 45dB spec is very different than a 70dB average spec, and that's pretty easy to understand.

Yep ) , carved in stone.

Well, I asked because seemingly noone publishes actual tests, and particularly not "meaningful" (to me at least) ones, no reference to applicable (if existing) standards, etc., nor empirical or field tests.
I hoped we could somehow progress a little bit on this other thread

The product you linked to has (like most if not all the competitors, I am not at all making a case of the specific make/model) has however what I call "vague" (or confusing if you prefer) descriptions, i.e. is described as having been made "with two layers of 80dB faraday fabric" and later it is described as "Blocks WiFi (2.4 & 5GHz), bluethooth, cell signals (even 4G LTE), GPS, RFID, and Radio signals with 80dB average attenuation.".

Average of what? ?

Do you need two layers of "80 db fabric" to obtain 80 db attenuation? 😯
