A user reports a number of inappropriate files appearing and disappearing from their computer. The technician identifies a program running that would appear to be the source of the rogue data. Which…

Investigating the file origin before reporting could compromise evidence, exceed the technician's authorization, or delay a required escalation in a potential incident response.

Reporting to management is the correct next step because the activity may have legal, HR, or security implications that exceed the technician's authority to handle alone. Management can engage the appropriate stakeholders - legal, HR, or security teams - and authorize further investigation or evidence preservation.

Preserving files is a later forensic step that should only be undertaken after management has been informed and authorized the technician to do so.

Documenting the service call result is a final step performed after the incident has been addressed, not immediately after discovering suspicious activity.
