Why financial services attracts the largest phishing share
Financial services receives 23.5 percent of all phishing volume according to APWG 2025 measurement, the largest single-sector share of attacker attention. The structural reason is obvious: the sector moves money. Successful phishing against a finance-team mailbox enables business email compromise wire-fraud (see /by-attack/bec); successful phishing against a retail-banking customer enables account takeover and ACH fraud; successful phishing against a wholesale-banking treasury team enables outbound wire transfers measured in tens of millions. The attacker economics favour the sector because the conversion path between successful credential theft and realised dollar loss is shorter than in any other vertical.
The defender economics in finance are unusual because the regulatory layer is heavier than in any other sector except healthcare. NYDFS 23 NYCRR 500 (for New York-licensed entities), FFIEC supervisory guidance (for federally-regulated banks), GLBA Safeguards Rule (for any financial institution), state Department of Financial Services or equivalent rules in most US states, and the EU DORA framework (for EU-regulated entities) all impose overlapping cyber-control requirements that materially raise the cost of both pre-event compliance and post-event remediation. Per-incident breach cost of $5.90M reflects the regulatory layer on top of the direct loss; without the regulatory layer the figure would be materially lower.[IBM 2025 financial-services cohort + APWG 2025 sector-share table]
