description: "This playbook creating an array called \"Suspicious Elements\", which is used to count potential security threats. The following elements can be added to the array:\n\n- \"IP Reputation\" - DBot Score is 2-3 \n- \"Source geolocation\" - RDP Connection made from rare geo-location \n-  Related to campaign - IP address is related to campaign, based on TIM module\n-  Hunting results - the hunt for indicators related to the source IP and the related campaign returned results\n-  XDR Alert search - XDR Alerts that related to the same username and endpoint, and to the MITRE tactics that comes after \"Credential Access\", were found.\n- Risky User - one or more risky users are involved in the incident, as identified by the Cortex Core - IR integration's ITDR module.\n- Risky Host - one or more risky hosts are involved in the incident, as identified by the Cortex Core - IR integration's ITDR module.\n\nThe array will then be outputted and its size will be compared to a final threshold. If the size is greater than or equal to the threshold, the investigation's final verdict will be deemed a \"True Positive.\""
