• Identify a value from the event payload that will be used as the basis for this threat detection.You must first determine the specific piece of information within the log payload that signals the malware outbreak activity you want to detect.
• Create a custom property to extract the value from the logs.QRadar needs a custom property to isolate this specific value from the raw log data in a structured way.
• Ensure the custom property is optimized and enabled.Optimize the custom property's extraction method for accuracy and efficiency. Ensure it's enabled, so QRadar actively parses this data element.
• Create and Configure a rule to create an offense that uses the custom property as the offense index field.Now that the custom property is ready, create a rule that references this property. Designate the custom property as the rule's offense index field to ensure offenses are correctly grouped based on the extracted malware indicator.

The MITRE ATT&CK heatmap within the QRadar Use Case Manager app visualizes how well your security defenses align against the MITRE ATT&CK framework. The colors on the heatmap are determined by the following:

• Level of Mapping Confidence: The confidence level with which QRadar has associated offenses to specific MITRE ATT&CK techniques. The colors indicate:
• Number of Offenses Generated: The frequency of offenses observed that map to a particular MITRE ATT&CK technique. A higher number of offenses will result in a deeper shade within the color gradient (i.e., dark red vs. light red).
