Présentation
The figure counts email addresses, not people. A maximum of approximately 380 contracting companies remains under review. Other membership fields vary by customer company. The shared-environment subtotal was corrected to 2,842,400; overlapping categories must not be summed again. A maximum of approximately 7.13 million fraudulent emails sent is a different metric. Do not add this root-event scope to SEGA-specific impacts.
