An EDR alert at a municipal utility shows Windows Security event 4698 on a billing workstation: Subject Account Name jmorales (a clerk), Task Name \Microsoft\Windows\Upd\SyncHealth, Task Content pointing to C:\Users\Public\wsvc.exe with a trigger of every 15 minutes. The task was created at 11:52 on a Saturday. What should the analyst conclude?

• AThis is a routine Windows Update health task and the alert is a false positive
• BThe clerk installed unapproved software, so the ticket goes to the help desk as a policy matter
• CThe 4698 event proves the workstation was accessed over RDP by an outside attacker
• DA scheduled task is being used for persistence (ATT&CK T1053.005) and the host should be triaged as compromised
