Microsoft Defender Threat Intelligence (Defender TI) now includes File Hash and URL Search capabilities, enabling researchers, analysts, hunters, and security responders to search for high-quality threat intelligence, including verdicts and associated metadata. This feature empowers security professionals to effectively utilize threat intelligence in their threat-hunting and investigation activities.
Defender TI leverages Microsoft's threat intelligence through static and dynamic analysis of files and URLs within and outside its ecosystem, providing comprehensive coverage of potential threats. The static study examines the file's code without executing it, while dynamic analysis involves executing it in a controlled environment to observe its behavior. This dual approach enables Defender TI to identify and categorize potential threats using static analysis techniques and detect and analyze actual behavior using dynamic analysis techniques. Users can search any hash or URL using the search bar circled below:
In the case of a Hash search, the Hash value would be entered into the search bar:
If there is any Intelligence on that Hash value, the information returned should look something like this:
In the case of an URL search, the URL would be entered into the search bar:
If there is any Intelligence on that URL, the information returned should look like this:
Take note of the intelligence retrieved from the search. The Summary tab displays the reputation score and basic information for the file hash or URL entities, while the Data tab provides detailed insights directly from MDTI. For instance, the returned result may show that the hash has a malicious reputation score, with a list of triggered rules contributing to the score.
This provides a straightforward way to obtain insights about the file hash or URL and any associated links to intelligence articles where the file hash or URL has been listed as an Indicator of Compromise. With this information, security professionals can better understand potential threats and take appropriate action to protect their organization.
In summary, including Hash and URL Intelligence within Defender TI to leverage static and dynamic analysis has been a top customer-requested feature. It enables SOC analysts, threat hunters, and other information security professionals to obtain detailed intelligence on specific hashes or URLs identified within their network. This capability empowers security teams to improve their operations and processes effectively.
By leveraging Defender TI's extensive threat intelligence capabilities, organizations can better comprehend potential threats and respond promptly to mitigate risks, enhancing their overall security posture. Microsoft's continued commitment to providing customers with the necessary tools and resources to protect against cyber threats is exemplified through this valuable addition to Defender TI.
