DSaaS Python Script to Search for Global Rule by HASH

Would like to use Python to search the DSaaS global rules to see if a certain HASH/SHA256 is in the global rule set.

Code below. How do I get the SHA256 value (hash256) in the search_filter object?

    hash256 = str(input("Pleas enter the hash that you would like to search: "))
    print(hash256)

    try:
        search_filter = deepsecurity.SearchFilter()

        api_response = api_instance.search_global_rules(api_version, search_filter=search_filter)
        pprint(api_response)
    except ApiException as e:
        print("An exception occurred when calling GlobalRulesApi.search_global_rules: %s\n" % e)

Not getting the search to work by HASH

In order to perform a search on the Application Control Global Rules you will need to first create a SearchCriteria as follows

# Create SearchCriteria
searchCriteria = deepsecurity.SearchCriteria(
    field_name='sha256',
    string_test='equal',
    string_value=hash256
)

and then add it to your SearchFilter object

search_filter = deepsecurity.SearchFilter(search_criteria=searchCriteria)

Overall your code will be as follows

hash256 = str(input("Please enter the hash that you would like to search: "))
print(hash256)

# Create SearchCriteria
searchCriteria = deepsecurity.SearchCriteria(
    field_name='sha256',
    string_test='equal',
    string_value=hash256
)

# Add SearchCriteria to SearchFilter
search_filter = deepsecurity.SearchFilter(search_criteria=searchCriteria)

try:
    api_response = api_instance.search_global_rules(api_version, search_filter=search_filter)
    pprint(api_response)
except ApiException as e:
    print("An exception occurred when calling GlobalRulesApi.search_global_rules: %s\n" % e)
