The "Permission Theft - Prevented - Elastic Endgame" rule is designed to detect and alert on prevention events involving token manipulation attempts, which are common methods employed by attackers for privilege escalation. The rule utilizes a KQL query to identify alerts generated by Elastic Endgame, focusing specifically on events categorized as 'prevention' related to 'token_protection_event', indicating blocked attempts to manipulate access tokens. With a risk score of 47, this rule can generate a significant number of alerts (up to 10,000 per run) and is part of a broader threat detection strategy aimed at safeguarding against unauthorized privilege escalation via access tokens. Investigation steps include reviewing alert specifics, examining related user and system activity, and determining if false positives arise from legitimate administrative actions. The rule encourages continuous monitoring and response protocols to mitigate any actual unauthorized access attempts and refine detection processes over time.
