Okta 2023 Breach Indicator Of Compromise: Suspicious User Account Creation/Activation
This rule detects the creation or activation of new user accounts in Okta with specific display names, such as 'svc_network_backup', which were identified as indicators of compromise during the Okta Support System 2023 breach. It aims to flag suspicious account activity that could indicate unauthorized access or persistence by an attacker. The rule can be improved by filtering out legitimate usernames if 'svc_network_backup' is a known and authorized account in the environment.
