![]() ![]() Generally, the rules do not work without specifying a config file, so you can use the config files in the tools directory during the conversion phase. We can specify the path to our config file with the -c parameter. sigmac -t splunk -r /home/kali/sigma-master/rules/web/ Converting the Ruleset With the –r parameter, we can specify the path of the rule to be converted as recursive. If we want it not to show the errors on the backend during the conversion process, we can use the -I parameter. sigmac -t splunk -r /home/kali/sigma-master/rules/web/web_webshell_keyword.yml Transforming the Single Rule With the -r parameter, you can specify the path of the rule to be translated as recursive. With the -t parameter, it selects the target platform to be translated. There are multiple ways to convert the rule. You can see the instructions for using the sigmac tool with the command below. It converts the rules we have written with the Sigmac application in the tools directory, in accordance with the platform to be used. In order to use this tool developed with Python, we first install the necessary sigma tool. It is included in the vehicles section of the Vehicle Sigma project. ![]() We will use the “sigmac” tool to test the rules we have written. title: Apache Robots.txt Detectionĭescription: When a request is made to the Robot.txt page via URL Strings, the necessary alert will be generated. The important thing here is the Detection area, which will determine the effectiveness of our rule. Since robots.txt is visited by bots, it will generate FalsePositive. We made our definition as seen below. Here, we want an alert to be generated when the robots.txt page is entered. Our first rule is to assume that we have a web service running on Apache.
