From Seizure to Evidence Storage to Data Extraction


The Mission Darkness™ Blocker Locker 7™ system solves multiple problems for forensics investigators and labs. To effectively access and recover data from cell phones and tablets, the latest forensic tools require devices to stay live. It can be difficult to keep devices shielded from RF signals, charged at all times, and securely locked. The Blocker Locker 7 accomplishes all of these objectives in a single cabinet designed specifically for shielding, charging, and locking. The unit includes seven fully loaded compartments equipped with Window Charge & Shield Faraday Bags for Phones, while additional Charge & Shield Faraday Bags can be purchased as required or to increase capacity.


The charging feature is designed to prevent lockout mode and reduce the amount of time needed to break a passcode, enabling the maximum amount of data extraction and unlocking with tools like GrayKey, Cellebrite, Magnet, XRY, BlackBag, Oxygen, etc.


To extract data from a device in the Blocker Locker 7, simply unlock the individual compartment, disconnect the power cable, remove the Charge & Shield Faraday Bag, and transfer it into a forensic faraday box. The bag can be easily opened inside the box (the magnetic NeoLok™ closure reduces faraday glove abrasion) while the device is passed into the shielded enclosure. Shielding and power are never compromised, providing a seamless process for investigators.



Watch the Field to Lab demo video to see why the Blocker Locker 7 is an integral part of the digital evidence handling process.

  • Digital evidence (cell phones and tablets specifically) should be RF shielded and remain charging from the point of seizure all the way to the lab, for maximum data recovery and password cracking with tools like Cellebrite and GrayKey. Simple Velcro faraday bags no longer support this entire process. This video shows the specific set of products that are required to ensure devices are not remote wiped and do not die en route to the lab. It is important to understand that traditional digital evidence handling techniques are insufficient for current data extraction and password recovery tools.

Blocker Locker System Usage Steps


1) Insert Device in a Window Charge & Shield Faraday Bag


Once a cell phone, tablet, or similar device is received at the police station, the officer places it inside a vacant Mission Darkness Window Charge & Shield Faraday Bag, which is stationed inside each Blocker Locker compartment. The corresponding cable tip (provided in the bag’s zipper pocket) is used to connect the device to the bag’s inner USB port. The bag is then sealed using the NeoLok™ magnetic closure.


2) Connect the Bag to Power


The officer connects the shielded USB A/M to A/M cable that is plugged into the locker compartment power outlet to the outer USB port on the Window Charge & Shield Faraday Bag. Device status can be confirmed by viewing the screen through the bag’s transparent window.


3) Lock the Bag in a Blocker Locker Compartment


The officer locks the compartment, then puts the key in the dropbox, and leaves evidence notes relating to the locker contents. The device can remain in the compartment securely locked, charged, and shielded indefinitely.


4) Disconnect the Bag From Power


At the point when passcode breaking or data extraction is to occur, the individual handling the evidence uses a key (either the master or corresponding one) to open the locker compartment. The user disconnects the USB cable connected to the outer USB hub on the bag, and removes the sealed bag from the compartment.


5) Transfer for Data Extraction


The device remains shielded in the Window Charge & Shield Faraday Bag while it is transferred to the lab or location where it will be analyzed.


*Further steps vary depending on the usage scenario (see below).


Additional Usage Scenarios


How to Use With GrayKey, Cellebrite, or Other Forensic Tools


  • The Window Charge & Shield Faraday Bag can be transferred to an RF shielded room or faraday forensic box for use with unlocking tools like GrayKey.
  • If using with a forensic box like the Mission Darkness BlockBox Lab XL, place the GrayKey unit inside the box and connect it to the inner RJ45 ethernet port.
  • Insert the Window Charge & Shield Faraday Bag carrying the device into the box and close the lid.
  • Place hands in the conductive gloves to open the Window Charge & Shield Faraday Bag and remove the device. The NeoLok magnetic closure is easy to open inside the box and reduces faraday glove abrasion (compared to Velcro closure bags).
  • The device can then be connected internally to GrayKey, Cellebrite, or other forensic tool.


How to Transfer a Device From a Standard Faraday Bag to a Window Charge & Shield Faraday Bag


  • If a device arrives to the police station already in a standard faraday bag, it can be transferred to a Window Charge & Shield Faraday Bag using a forensic box with hands-on access.
  • Simply place both bags inside the forensic box, close the lid, and transfer the device using the conductive gloves. Faraday bags with a NeoLok magnetic closure are preferred when being handled by conductive gloves.


If Using a Window Charge & Shield Faraday Bag Without the Blocker Locker


  • The Window Charge & Shield Faraday Bag can be purchased and used independently without the Blocker Locker. The USB filter enables the device to receive power while it is transferred throughout various locations such as a vehicle, desk, or evidence cabinet, until it can be analyzed in a different location.
  • Use the shielded USB A/M to A/M cable attached to the outer side of USB filter to connect a portable battery or power outlet to charge the device inside.
  • For data extraction, the user simply disconnects the power source and connects to an extraction tool.
