Managing YARA Rules

Dr.Web vxCube provides advanced capabilities for working with YARA rules. In the meta section, you can specify file behavior category to be displayed in the report if the rule matches. To create rules that are triggered on certain file behavior, you can use the dr_sandbox module.

1.Click _ru_Image_add Add. The window with sample rule code appears.

2.In place of RuleName1 enter the rule’s name using letters, digits, or underscore.

3.Change TAG1 and TAG2 tags to your desired tags if necessary. They will be included in the report if this rule is triggered during the analysis.

4.Specify the file behavior category that will be assigned to the file if the rule is triggered. Possible values: "neutral", "suspicious", "malware".

5.Add other parameters and conditions for the rule.
