Attackers impersonate healthcare.gov or CMS with fake \"your Special Enrollment Period is closing — enroll now or lose coverage / your current plan will lapse\" urgency, leading victims to fake marketplace portals harvesting SSN, income details, subsidy verification documents, and insurance information. The ACA marketplace is particularly susceptible because (1) real enrollment deadlines create genuine urgency, (2) subsidy eligibility varies by income making \"verify your income\" lures plausible, and (3) millions of uninsured Americans actively look for enrollment opportunities. Legitimate CMS / Healthcare.gov enrollment communications originate from healthcare.gov and cms.gov. The signal fires when: (1) body references Healthcare.gov, CMS, ACA, Marketplace, Special Enrollment Period, or open enrollment AND (2) enrollment deadline / coverage lapse / subsidy qualification urgency is present AND (3) sender is NOT healthcare.gov, cms.gov, hhs.gov, or getcoveredamerica.org AND (4) no List-Unsubscribe or In-Reply-To.
