The Miami Cybersecurity Landscape: Why South Florida Is a Target

Cybercrime follows money, and money flows through Miami. The metro is home to more international bank branches than any US city outside New York, a deep crypto and fintech bench, the largest cruise port in the world, one of the densest concentrations of family offices in the Western Hemisphere, and a real-estate market where eight-figure all-cash closings are routine. Every one of those concentrations is a target.

What we see in client telemetry

Wire fraud on real-estate closings

South Florida title companies and real-estate attorneys are repeat targets for business email compromise tuned to the closing workflow. The typical pattern: attacker compromises the email of one party to the transaction (often weeks before closing), monitors for the wire instructions, then sends spoofed instructions from a lookalike domain right before funds are due. Local FBI field-office advisories have flagged this as a sustained campaign every year since 2019.

Yacht and aircraft purchase wires

Same playbook, larger amounts. Yacht brokers, aircraft brokers, and the law firms supporting them see the same wire-fraud pattern with seven- and eight-figure stakes. Most local marina and FBO infrastructure is owned by small operators with limited security maturity — which is exactly why they're targeted.

Spanish-language lures aimed at LATAM-facing companies

Miami's role as the commercial hub for Latin America makes Spanish-language phishing materially more dangerous here than in most US metros. Lures impersonate regional banks, customs brokers, and shipping agents. Generic English-language phishing training doesn't prepare staff for it; localized training does.

Family-office social engineering

Family offices and high-net-worth households are a particularly difficult attack surface: the operational team is small, the spend authority is large, and the principal often resists security friction. We see attackers patiently building relationships with house managers, personal assistants and CFOs — sometimes over months — before triggering a wire request, vendor change, or 'urgent' instruction.

Crypto and fintech targeting

Miami's crypto scene draws the full spectrum of crypto-native attacks: SIM swaps targeting executive phone numbers, smart-contract phishing, fake-recruiter approaches on LinkedIn aimed at engineers with key access, and supply-chain attacks against the dev tooling these companies use.

What's working locally

• Hardware-key MFA on every account that can authorize, approve, or move money. Passkeys are catching up, but FIDO2 hardware keys remain the gold standard for principals and signatories.
• Callback verification on any wire over a fixed threshold ($50K is a common starting point), to a known phone number — not the number in the email.
• Threat-intelligence feeds tuned to Caribbean and LATAM infrastructure, not just generic US IOC streams.
• Localized phishing-simulation campaigns in Spanish and Portuguese, not just English.
• Quarterly tabletop exercises with executives and principals — not just IT. The wire that goes out is the wire the principal approved.

What isn't working

• 'We're too small to be a target.' The smallest local breach we've responded to was an 11-person professional-services firm; the loss was $487K and the firm did not survive the year.
• Outsourcing to a generic MSSP three time zones away. Response time and local context both matter when the wire is leaving today.
• Treating Miami's location as a marketing asset without addressing the threat picture that comes with it. International exposure cuts both ways.
• Relying on the bank's fraud detection to catch wire fraud. Bank fraud teams catch some of it. They are not the last line of defense — your controls are.

What we recommend for South Florida businesses

1. 1Treat wire workflows as a security-critical process. Document them, dual-control them, callback-verify them, exercise them quarterly.
2. 2Deploy phishing-resistant MFA universally, not just on admin accounts. Spanish-language BEC targets sales staff just as often as it targets finance.
3. 3Run quarterly Spanish + English phishing exercises if you have any LATAM-facing operations.
4. 4Engage local incident response. Same-time-zone, on-site-when-needed response materially reduces dwell time and reputational damage.
5. 5Maintain a cyber-insurance policy with a known IR firm and pre-approved hourly rates. South Florida claim activity has driven premiums up — make sure you're getting the coverage you're paying for.
