As DC3’s technical solutions component, TSD supports DC3 Mission Areas, as well as the DoD Intelligence and Law Enforcement communities.
TSD Overview

Technical Solutions Development (TSD) tailors innovative software and system solutions engineered to the specific requirements of digital forensic examiners and cyber intrusion analysts. TSD validates digital forensic tools from commercial off-the-shelf, government off-the-shelf, and open source domains to ensure relevancy and reproducibility as to expected use. In coordination with its cooperative partners, TSD:

• Leads the way by proactively identifying, researching and evaluating relevant new technologies, techniques and tools

• Actively participates in the development of industry standards, including Structured Threat Information eXpression (STIX) and Cyber-investigation Analysis Standard Expression (CASE)

Shares in-house-developed tools with federal, state, and local law enforcement partners

• Maintains the Counterintelligence Tool Repository (CITR), a warehouse of classified and unclassified tools that support digital forensics and counterintelligence needs


  
Technical Objectives

  • Proactively identify, research and evaluate relevant new technologies, techniques and tools
  • Design and develop digital forensic, analytic and enterprise workflow tools
  • Test DC3-developed software to ensure required performance and reliability 
  • ​​Validate digital forensic tools to ensure relevancy and reproducibility as to expected use
Tools & Validations

 

DC3 offers a number of open source and CUI tools and validations. 
Open source tools are available on GitHub and SourceForge.


CUI tools and validations for U.S. DoD and Federal law enforcement and counterintelligence (LE/CI) can be obtained by authorized personnel with a CAC or PIV through the DC3 Customer Portal.
All others should contact: dc3.tsd@us.af.mil.


 

CITR

 

The Counterintelligence Tool Repository (CITR) is a warehouse of classified and unclassified tools that support digital forensics and counterintelligence needs. Whenever possible, the actual tool is provided through the repository portal in the form of a downloadable executable. When a downloadable executable cannot be provided, the repository advises how to obtain the tool from the hosting agency.


Authorized personnel with a CAC or PIV may access this tool list through the DC3 Customer Portal. All others should contact dc3.tsd@us.af.mil

TSD Technologies
Technical Solutions Development (TSD) maintains, develops, and supports a large variety of tools and enterprise solutions for DC3 mission areas, DC3 customers, and other partnering agencies. Several notable efforts are highlighted below:

Analytic Customer Portal — The Analytic Customer Portal is a system that hosts a number of datasets for analysts both internal and external to DC3. The system provides users the ability to search DNS-monitored data, GeoIP data, and a social media database. Additionally, users can submit Requests for Information (RFIs) to the Analytic Group within DC3 (DC3/AG) at: https://analytics.dc3.smil.mil

Customer Portal —
 The Customer Portal houses a number of products and services of interest to external customers of DC3, including operational status updates, event coordination, and product download links. The Portal provides information on DC3 Cyber Forensics Lab (CFL) case status and regulates access to the DC3 legal document repository. Finally, the Portal serves as a management solution for DCISE TechEx events, with tools to assist in planning sessions and logistics, registering participants, and conducting post-conference surveys. The Customer Portal also provides access to TSD-developed tools as well as validation reports for forensics tools completed by DC3 and the U.S. Army. The toolbox that can be found in the Portal at https://customerportal.dc3.mil includes the following:
 
DC3 Advanced Carver (DC3AC) — DC3AC is a state-of-the-art, patented file-carving capability to extract complete or partial files from unknown data sets, which can include those found within unallocated space on device images, memory dumps, page files, and corrupt files. Targeted file formats can encompass images, videos, documents, databases, and executables. DC3AC contains a number of unique algorithms for identifying, reconstructing, and repairing file fragments that would otherwise be unreadable.
 
 
DC3 SQLite Dissect — DC3 SQLite Dissect is a SQLite file parser offering capabilities to recover and retrieve deleted information. Data is recovered through analysis of the contents of the SQLite files and generation of signatures for the data. Those signatures are then used to dissect unallocated space within the files. DC3 SQLite Dissect supports both SQLite databases and Journaling files. The tool uses a write-ahead log (WAL) to determine the timeline of events in order to reveal transactional history, which can be used to generate reports on user activity (e.g., the addition and deletion of data over time). DC3 SQLite Dissect includes an Application Programming Interface (API), and can export recovered results in multiple formats, such as CSV (Comma Separated Values), XLSX (Excel), and SQLite.

Electronic Malware Submission (EMS) — EMS allows both DC3 analysts and external customers to safely and securely submit malware for examination. Submitters have the option of requesting a thorough examination to be conducted by a reverse engineer from the Cyber Forensics Laboratory (CFL) within DC3, or requesting an automated analysis report (results of which can be available within minutes) generated by a combination of the dozens of exploitation tools created and curated by TSD and CFL subject matter experts. Submissions may be made at: https://ems.dc3on.gov
 
GeoSuite — GeoSuite is a set of capabilities centered around geospatial visualization and analysis. Currently, it consists of an offline geospatial mapping capability which supports plotting of files based on geo metadata and GeoIP, cell tower locations, along with Wi-Fi hotspots based on open source and commercial datasets. The second offering in the GeoSuite serves as a parsing tool to output data in a format which can be visualized in the mapping capability. Currently, the parser supports a number of commercial small Unmanned Aircraft Systems (sUAS), fitness trackers, and dash cams. Finally, in concert with the offline mapping capability, the third tool provides a visualizer for sUAS flight paths with associated telemetry data overlays.

Missing Links — Missing Links is a forensic analysis tool suite comprised of two software components: the Missing Links Explorer and the Missing Links Extractor. The concept sprang from the need to support forensic examiners,
in both field and lab settings, to be able to quickly identify the “missing links” – apparent gaps in the evidence associated with a particular case. The resulting suite of tools leverages the processing power of commercial tools to scale correlation capabilities across thousands of data sources and billions of forensic artifacts.
