Methodology and findings
A phishing report is both a customer request and a possible security signal. Record the sender, reported message, delivery time, affected account, and requested action before troubleshooting anything.
CISA guidance supports recognition and reporting practices. Do not ask a user to click a suspicious link to reproduce the issue, and do not make the support queue the place where risky content is casually opened.
Preserve relevant headers or attachments through the approved security path, mark what was actually inspected, and route suspected compromise to the named incident owner. Keep account recovery separate from message classification when the risks differ.
Review reports for missed escalation, unnecessary exposure, and unclear customer updates. Use findings to improve the intake wording and the boundary between helpdesk and security response.
