Files

A filelisting against a system. The files artifact is a unique compared to other artifacts.
Depending on the source option, artemis will return different type of filelisting.

Artemis currently supports 3 different types of filelisting:

• Host - Filelisting against a live system
• Zip - Filelisting against a zip file
• NTFS - Filelisting against a NTFS drive

Since a filelisting can be extremely large, every 10k entries artemis will output the data and then continue. However, iff binary parsing or timelining is enabled, then every 1k entries artemis will output the data and then continue.

Other Parsers:

• Any tool that can recursively list files and directories

• N/A

Collection Options

• start_path Where to start the file listing. Must exist on the endpoint. To start at root use C:\\. This configuration is required
• depth Specify how many directories to descend from the start_path. Default is one (1). Must be a postive number. Max value is 255. This configuration is optional
• metadata Get ELF data from ELF files. This configuration is optional. Default is false
• md5 Boolean value to enable MD5 hashing on all files. This configuration is optional. Default is false
• sha1 Boolean value to enable SHA1 hashing on all files. This configuration is optional. Default is false
• sha256 Boolean value to enable SHA256 hashing on all files. This configuration is optional. Default is false
• path_regex Only descend into paths (directories) that match the provided regex. This configuration is optional. Default is no Regex
• file_regex Only return entres that match the provided regex. This configuration is optional. Default is no Regex
• yara Either a base64 encoded Yara rule or a Yara rule hosted on a remote server
• source What type of filelisting to perform. This value can be:
  • host: - Represents a live filelisting
  • ntfs:C - Represents a NTFS filelisting against the C drive
  • zip:/full/path/to/file.zip - Represents a ZIP filelisting against file.zip
• verbose - Include additional entries in the filelisting
  • Currently this only affects the NTFS filelisting. This option carves INDX entries from INDX slack space
