PingCastle is a legitimate security tool designed to audit Active Directory environments for misconfigurations, vulnerabilities, and potential lateral movement paths. While intended for defensive assessment, threat actors often use it during the reconnaissance phase of an attack to identify high-value targets and exploitable security weaknesses in domain infrastructure.
Impact
Successful execution of PingCastle allows an operator to map the domain environment, identify privileged accounts, and find systemic weaknesses that can be leveraged for domain compromise.
Recommendation
Detection teams should monitor for the execution of PingCastle using process creation telemetry. Establish a baseline for authorized security assessment activity and alert on instances of PingCastle running from unauthorized hosts or user accounts.
Immediate actions
Deploy Sigma rule to detect known PingCastle command-line flags and binary signatures
Threat Hunt
Identify unauthorized AD enumeration activity by baselineing normal tool usage
Data: Process creation logs, User identity associated with tool execution
Mitigations
Implement application control to restrict the execution of unauthorized security binaries
Unauthorized reconnaissance tools
