Name:AWS CreateLoginProfile id:2a9b80d3-6340-4345-11ad-212bf444d111 version:12 date:None author:Bhavin Patel, Splunk status:production type:TTP Description:The following analytic identifies the creation of a login profile for one AWS user by another, followed by a console login from the same source IP. It uses AWS CloudTrail logs to correlate the `CreateLoginProfile` and `ConsoleLogin` events based on the source IP and user identity. This activity is significant as it may indicate privilege escalation, where an attacker creates a new login profile to gain unauthorized access. If confirmed malicious, this could allow the attacker to escalate privileges and maintain persistent access to the AWS environment. Data_source:
-AWS CloudTrail CreateLoginProfile AND AWS CloudTrail ConsoleLogin
| rename userIdentity.userName as new_login_profile
| stats count values(eventName) min(_time) as firstTime max(_time) as lastTime BY eventSource aws_account_id errorCode user_agent eventID awsRegion userIdentity.principalId user_arn new_login_profile src_ip dest vendor_account vendor_region vendor_product
| `security_content_ctime(firstTime)`
| `security_content_ctime(lastTime)`]
| rename user_arn as user
| `aws_createloginprofile_filter`
how_to_implement:You must install splunk AWS add on and Splunk App for AWS. This search works with AWS CloudTrail logs. known_false_positives:While this search has no known false positives, it is possible that an AWS admin has legitimately created a login profile for another user.
