Replay any dataset to Splunk Enterprise by using our replay.py tool or the UI. Initial Confidence and Impact is set by the analytic author. The Risk Score is calculated by the following formula: Risk Score = (Impact * Confidence/100). User $user_arn$ has concurrent sessions from more than one unique IP address $src_ip$ in the span of 5 minutes. AWS Identity and Access Management Account.Filter as needed and/or customize the threshold to fit your environment. Below the filters bar, you see the details of logged sessions (such as SPS Session Count.

As users may behave differently across organizations, security teams should test and customize this detection to fit their environments. The presence of this event occurring from two different IP addresses is highly unlikely. The Splunk Threat Research team leveraged this event name to identify 2 concurrent sessions. When a user navigates the AWS Console after authentication, the API call with the event name DescribeEventAggregates is registered in the AWS CloudTrail logs. Step 6: Verify user’s logon session time Here, you can see that VDOC\Administrator account had logged in (ID 4624) on at 10:42 PM with a Logon ID of 0x144ac2. This behavior could represent a session hijacking attack whereby an adversary has extracted cookies from a victims browser and is using them from a different location to access corporate online resources.
