This Week in Security: September 8, 2026

Security researchers this week documented a phishing technique that hides invisible Unicode characters inside financial keywords like funding, loan, advance, and credit. A person reading the email sees the word exactly as it should look; a filter scanning for that same word sees a broken string and lets the message through. Volume of this activity has spiked into the millions of messages on peak days.

Why this matters for your firm

For a Florida law firm, those specific words are the vocabulary of wire transfers, trust account disbursements, and settlement payouts, exactly the transactions a well timed phishing email is built to hijack.

Florida Bar Rule 4-1.6

Rule 4-1.6 requires reasonable efforts to prevent unauthorized access to client information, and a wire fraud scheme routed through a firm's own inbox is precisely the failure that rule guards against.

What to do this week

1. Treat any request to change wire instructions or payment timing as suspicious by default, and confirm it by phone using a known number, never by replying to the email.
2. Ask your provider whether filtering normalizes invisible Unicode before scanning.
3. Confirm multi factor authentication is enabled everywhere.
