The Sandbox Scryer is an open-source tool for producing threat hunting and intelligence data from public sandbox detonation output The tool leverages the MITRE ATT&CK Framework to organize and prioritize findings, assisting in the assembly of IOCs, understanding attack movement and in threat hunting By allowing researchers to send thousands of samples to a sandbox for building a profile that can be used with the ATT&CK technique, the Sandbox Scryer delivers an unprecedented ability to solve use cases at scale.

The tool is intended for cybersecurity professionals who are interested in threat hunting and attack analysis leveraging sandbox output data. The Sandbox Scryer tool currently consumes output from the free and public Hybrid Analysis malware analysis service helping analysts expedite and scale threat hunting.

The Sandbox Scryer is intended to be invoked as a command-line tool, to facilitate scripting

Operation consists of two steps:

  • Parsing, where a specified report summary is parsed to extract the output noted earlier
  • Collation, where the data from the set of parsing results from the parsing step is collated to produce a Navigator layer file

Invocation examples:

  • Parsing
  • Collation

If the parameter “-h” is specified, the built-in help is displayed as shown here Sandbox_Scryer.exe -h

           -h  Display command-line options
           -i  Input filepath
           -ita  Input filepath - MITRE report for top techniques
           -o  Output folder path
           -ft Type of file to submit
           -name Name to use with output
           -sb_name Identifier of sandbox to use  (default:  ha)
           -api_key API key to use with submission to sandbox
           -env_id Environment ID to use with submission to sandbox
           -inc_sub Include sub-techniques in graphical output  (default is to not include)
           -mitre_data Filepath for mitre cti data to parse (to populate att&ck techniques)
           -cmd  Command
                    parse  Process report file from prior sandbox submission
                           Uses -i, -ita, -o, -name, -inc_sub, -sig_data   parameters
                    col    Collates report data from prior sandbox submissions
                           Uses -i (treated as folder path), -ita, -o, -name, -inc_sub, -mitre_data   parameters

Once the Navigator layer file is produced, it may be loaded into the Navigator for viewing via

Within the Navigator, techniques noted in the sandbox report summaries are highlighted and shown with increased heat based on a combined scoring of the technique ranking and the count of hits on the technique in the sandbox report summaries. Howevering of techniques will show select metadata.
