PEP 8get_request
Check the status and results of an asynchronous request, such as hunt or exact-search. Supports a single request id at this time.
GetMalQueryEntitiesSamplesFetchV1
PEP 8get_samples
Fetch a zip archive with password 'infected' containing the samples. Call this once the /entities/samples-multidownload request has finished processing
PostMalQueryEntitiesSamplesMultidownloadV1
PEP 8samples_multidownload
Schedule samples for download. Use the result id with the /request endpoint to check if the download is ready after which you can call the /entities/samples-fetch to get the zip
PostMalQueryExactSearchV1
PEP 8exact_search
Search Falcon MalQuery for a combination of hex patterns and strings in order to identify samples based upon file content at byte level granularity. You can filter results on criteria such as file type, file size and first seen date. Returns a request id which can be used with the /request endpoint
