GCIH · Question #731

A security team is actively monitoring windows event IDs 4634, 4688, and 4697. Which persistence mechanism will they detect with this approach?

The correct answer is C. New Service creation. Windows Event ID 4697 specifically logs new service installation, making it the direct indicator for detecting service-based persistence when combined with process and session events.

Why each option

Windows Event ID 4697 specifically logs new service installation, making it the direct indicator for detecting service-based persistence when combined with process and session events.

AGolden ticket use

Golden ticket attacks are detected via Kerberos-related event IDs such as 4769 with anomalous ticket lifetimes or forged PAC attributes, not through 4634, 4688, or 4697.

BWeb shell placement

Web shell placement is detected via file system auditing event 4663 or web server access logs, not through process creation or service installation events.

CNew Service creationCorrect

Event ID 4697 ('A service was installed in the system') is generated whenever a new service is created, directly detecting this persistence technique. Event ID 4688 logs new process creation and would capture the service executable being launched, while 4634 logs account logoffs that may appear during the attacker session. Together, these three IDs form a correlated detection chain specifically suited to new service-based persistence.

DLocal Account addition

Local account addition is detected by Event ID 4720 ('A user account was created'), which is not included in the monitored set.
