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 or RF shielded room. The bag can be easily opened inside a faraday box (the patented NeoLok™ magnetic 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.


The Blocker Locker exterior was updated to a black finish with a striped design in October 2022, as shown in the image above. The usage steps and interior compartments remain the same as the previous model with a gray finish.

A matching industrial-grade aluminum locker stand was introduced in January 2024. The add-on accessory stand elevates the locker to a more user-friendly height, optimizing workspace by liberating desk or counter areas, and supporting the locker's weight. This eliminates the need for extensive installation, as anchoring the unit to a wall suffices.

Tools required to keep devices live from the field to the lab

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 while 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. Read the blog post for more details.

Keep digital forensics evidence on cell phones and tablets locked, charged, and shielded from RF signals

Introduce new devices by placing them inside the Charge & Shield Faraday Bag stationed inside each locker compartment

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. An external cable lock ensures that the cable isn't disconnected unintentionally. 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 the corresponding one) to open the locker compartment. The user unlatches the external cable lock, 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.

Once passcode unlocking software is installed on the device and RF shielding is no longer required, the device can be transferred to the Forensic Crack Cabinet, as shown in the video

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.
  • *When in use, never open a faraday bag unless the environment is RF shielded (such as a faraday box or tent).

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 RF shielded 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 through the USB filter, the user simply disconnects the power source and connects to an extraction tool.
