When a compromised endpoint is detected, D3 enriches the alert with threat intelligence from Falcon X and other sources to get a risk score. If the file is not conclusively known to be malicious, D3 then queries the compromised endpoint via Falcon Endpoint Protection to download the file, where it can then be detonated in Falcon Sandbox for analysis. If the file is determined to be malicious, D3 can then query other endpoints to find any other instances of the file. Having now identified the full extent of the compromise, the analyst can use D3 to orchestrate actions across the affected endpoints, such as to remove the file, block the hash, kill processes, or quarantine the endpoint.
When D3 ingests an event from Falcon, it correlates against MITRE ATT&CK to determine the adversarial techniques. D3 then collects other relevant endpoint events based on parameters such as the general timeframe of the attack. D3 parses those endpoint events to find and categorize correlated IOCs, techniques, and tactics. D3 then maps these data points across the MITRE ATT&CK framework to build out the kill chain of the larger attack that these pieces represent.
