What is it?

MITRE ATT&CK (https://attack.mitre.org/) is an amazing knowledge base of adversary techniques.

MITRE ATT&CK® is a globally-accessible knowledge base of adversary tactics and techniques based on real-world observations. The ATT&CK knowledge base is used as a foundation for the development of specific threat models and methodologies in the private sector, in government, and in the cybersecurity product and service community.

With the creation of ATT&CK, MITRE is fulfilling its mission to solve problems for a safer world — by bringing communities together to develop more effective cybersecurity. ATT&CK is open and available to any person or organization for use at no charge.

Where is it?

"Reporting" -> "ATT&CK Mappings" will allow you to see the MITRE ATT&CK Matrix (Before the new sub techniques).

How Do I use it?

You can click on "Command by ATT&CK" to see a highlighted area of all the possible commands that Mythic knows about and how they map to ATT&CK. You can also click on "Tasks by ATT&CK" and see information on all the commands that have been executed in the current operation that map to MITRE ATT&CK. This shows the difference between the realm of what's "possible" for you to cover and what all you have already covered.

How does this Task mapping happen?

Commands can be automatically tagged with MITRE ATT&CK Techniques (this is what populates the "Commands by ATT&CK" output). To locate this, you just need to look at the associated python files for each command:

/Mythic/Payload_Types/[agent name]/mythic/agent_functions[cmd_name].py

In addition to this file defining the general properties of the command (such as parameters, description, help information, etc). There's a field called attackmapping that takes an array of MITRE's T# values. For example, looking at the apfell agent's download command:

class DownloadCommand(CommandBase):
    cmd = "download"
    needs_admin = False
    help_cmd = "download {path to remote file}"
    description = "Download a file from the victim machine to the Mythic server in chunks (no need for quotes in the path)."
    version = 1
    is_exit = False
    is_file_browse = False
    is_process_list = False
    is_download_file = True
    is_remove_file = False
    is_upload_file = False
    author = "@its_a_feature_"
    parameters = []
    attackmapping = ["T1020", "T1030", "T1041"]
    argument_class = DownloadArguments
    browser_script = BrowserScript(script_name="download", author="@its_a_feature_")

When this command syncs to the Mythic server, those T numbers are stored and used to populate the ATT&CK Matrix. When you issue this download command, Mythic does a lookup to see if there's any MITRE ATT&CK associations with the command, and if there are, Mythic creates entries for the "Tasks by ATT&CK" mappings. This is why you're able to see the exact command associated.

How do I update this to add/remove mappings?

As long as you're keeping with the old MITRE ATT&CK mappings, simply add your T# to the list like shown above, then run sudo ./start_payload_types.sh [agent name]. That'll restart the agent's container and trigger a re-sync of information.

MITRE Added Sub-Techniques, where are they?

Good point. The current Mythic instance doesn't support the new sub technique view or mapping scheme. It's on the roadmap to incorporate now that MITRE finalized the structure.
