One of the most common and rapidly evolving threats is phishing. Learn how to protect you and your business against phishing attacks.

Navigating the Rise of AI-Generated Phishing Attacks

At BankUnited, our relationships with clients are built on trust and personalized service. As digital banking continues to grow, the risks are evolving as well. We are committed to protecting your financial information and identity, and we encourage you to stay informed and vigilant.

One of the most common and rapidly evolving threats is phishing. What was once easy to spot has become far more sophisticated and widespread. Today, it is part of a global, multi-billion dollar problem, with cybercriminals increasingly using advanced technologies such as artificial intelligence to make their attacks more convincing.

The Numbers Around Phishing Attacks

The Reality: Why Vigilance is Essential

Cybersecurity is a critical pillar of your financial well-being. The data from the past year highlights why constant awareness is your best defense:
  • The Global Impact: Total reported cybercrime losses reached $21 billion in 2025.
  • The Financial Sector: Attacks on financial institutions remain the most frequent and costly, with the average breach cost rising to $6.08 million.
  • The AI Surge: Phishing attacks utilizing generative AI have increased by over 1,200% since late 2023.

The Evolution: Scams Without the Typos

In the past, spotting a scam was easier because of broken English or obvious spelling errors. Today, AI allows fraudsters to generate perfectly written, highly personalized messages that look exactly like legitimate communication from a colleague or a trusted institution.

A Quick Security Reminder: BankUnited will never send you an unsolicited email or text asking for your account number, password, PIN, or Social Security number. If a message creates an intense sense of urgency to provide this info, it is a red flag.

Anatomy of a Standard Phishing Email

The Fuel for the Fire: Your Social Footprint

While AI can help generate convincing messages, information shared on social media often makes them more believable. Fraudsters use publicly available details to tailor messages and make urgent requests seem legitimate.

Oversharing on Social Media Leads to Risk

How to Spot a Suspicious Message

Even the most sophisticated AI scams leave technical "tells." To protect your accounts, look past the professional language and check the message’s infrastructure:
  • The Mismatched Sender: An email may say it is from BankUnited, but the actual sender address might be security-update@scam-server.com.
  • The Hover Test: Before clicking any link, hover your mouse over it. Does the destination URL match our official secure domain, bankunited.com?
  • Logo Imitation: Look for slightly pixelated logos or out-of-date branding that doesn't match our official site.

The Sophistication Level of AI Phishing

Your 5-Step Shield

We encourage all our clients to adopt these five habits to ensure their banking remains secure:
  • Stop. Verify the sender’s actual email address.
  • Look. Hover before you click to see the true link destination.
  • Think. Be skeptical of any email that demands "immediate action" to avoid account closure.
  • Verify. Call our Client Care Center at (877) 779-BANK (2265) if you are ever in doubt.
  • Protect. Ensure Multi-Factor Authentication (MFA) is active on all your sensitive accounts.
