Connect to platforms such as Elasticsearch or Azure Sentinel via their APIs.That’s a great question! What if I told you that you could: Then, why do I need Jupyter Notebooks? 🤔

That means that if you are using any of those tools to query security events, you can easily get a sigma rule converted to their format and run it.

If you are wondering how to get that information, you can get it by running this sigmac script with the following flag: sigmac -l

Let’s take a look at this sigma rule: sysmon_wmi_event_subscription.yml title: WMI Event Subscription id: 0f06a3a5-6a09-413f-8743-e6cf35561297 status: experimental description: Detects creation of WMI event subscription persistence method references: - tags: - attack.t1084 - attack.persistence author: Tom Ueltschi date: 2 logsource: product: windows service: sysmon detection: selector: EventID: - 19 - 20 - 21 condition: selector falsepositives: - exclude legitimate (vetted) use of WMI event subscription in your network level: high What can I do with it?Īccording to Sigma’s Sigma Converter (Sigmac) documentation, as of, you can translate rules to the following query formats: Writing an Interactive Book 📖 over the Threat Hunter Playbook 🏹 with the help of the Jupyter Book Project 💥.What the HELK? Sigma integration via Elastalert.I highly recommend to read a few of my previous blog posts to get familiarized with some of the concepts and projects I will be talking about in this one: In this post, I will show you how I translated every rule from the Sigma project to Elasticsearch query strings with the help of sigmac, created Jupyter notebooks for each rule with a python library named nbformat and finally added them to the HELK project to execute them against Mordor datasets.

#Quickbuild splunk logging code

It sounded very easy to do at first, but I had no idea how to create notebooks from code or how I was going to execute sigma rules on the top of them.

R = requests.post(self.Happy new year everyone 🎊! I’m taking a few days off before getting back to work and you know what that means 😆 Besides working out a little bit more and playing with the dogs, I have some free time to take care of a few things in my to-do list for open source projects or ideas 😆🍻 One of them was to find a way to integrate Jupyter Notebooks with the SIGMA project. First I created a file loggingsetup.py where I configured my python loggers with dictConfig: LOGGING = Does anybody have an idea what's wrong with my code?Īfter hours of figuring out what eventually could be wrong with my code, I now have a result that satisfies me. When activating debug on splunk handler (set to True), the splunk handler logs out that there is no payload available as already posted above. # splunk_tLevel(os.getenv('LOGGING_LEVEL', 'DEBUG')) # splunk_tFormatter(logging.BASIC_FORMAT) # port=os.getenv('SPLUNK_HTTP_COLLECTOR_PORT'), # host=os.getenv('SPLUNK_HTTP_COLLECTOR_URL'), Here I connect to the setup_logging signal from celery config_loggers(*args, **kwags): Splunk_tLevel(os.getenv('LOGGING_LEVEL', 'DEBUG'))Ĭelery initialisation (not sure, if worker_hijack_root_logger needs to be set to False.) app = Celery('name_of_the_application', broker=CELERY_BROKER_URL) Port=os.getenv('SPLUNK_HTTP_COLLECTOR_PORT'),

Host=os.getenv('SPLUNK_HTTP_COLLECTOR_URL'), This is how I set up the logger at the beginning of the file logger = logging.getLogger(_name_) I tried several things, including connecting the setup_logging signal from celery to prevent it to overwrite the loggers or setting up the logger in this signal. How do I set up the loggers correctly, so that all the logs go to the splunk_handler?Īpparently, celery sets up its own loggers and overwrites the root-logger from python. Timer thread executed but no payload was available to send But if I run it together with celery there seem to be no logs that reach the splunk_handler. If I run the splunk_handler without celery locally, it seems to work. I am trying to use this splunk_handler library. I want to send my logs directly from the script to splunk. I have a python script running on a server, that should get executed once a day by the celery scheduler.
