Case Brief

Open enrollment week means every finance mailbox gets flooded with HR-looking mail. Wealth advisor a.chen@straylight.finance hit report on a "2026 Benefits Enrollment Window" message because the enroll portal is not the one Straylight publishes. Tess wants a clean call: spoofed enrollment phish, or noisy false positive during benefits season.

Objective

Decide if the message is malicious, cite the auth and domain evidence, and recommend quarantine or block before more advisors click through.

Learning Objectives

Prove whether SPF, DKIM, and DMARC failed or passed for the reported message
Separate the real Straylight brand from lookalike sender and enrollment domains
Capture the portal URL and originating IP as ticket-ready IOCs
Close with a disposition and containment action you can defend to Tess
