A New York story
The Tuesday the trust account wire changed its mind
the managing partner of a nine-lawyer real-estate practice on Madison Avenue
It is a Tuesday in October and the closing is at three. The managing partner runs a nine-lawyer practice on Madison Avenue, eleven floors up, and a $1.4 million payoff has to leave the trust account before the buyer's bank closes. The paralegal has done two hundred of these. She is good at them.
At 11:15 the seller's attorney sends updated wire instructions. Same thread, same signature block, same typo in the subject line he has used since August. The bad guy has been sitting in that lawyer's mailbox for three weeks, reading, waiting for a Tuesday like this one. He changed one thing at the bottom of the signature: the phone number.
She does what the firm's policy says and calls to confirm. A pleasant voice picks up on the second ring and confirms the new account.
She stops. She calls the number from the engagement letter instead, and a different attorney says he sent nothing this morning. The wire goes out at 2:50, to the right bank. Nobody has to explain to a client where his house money went.
Her cursor is on the release button when the firm's email filter flags the reply address as a lookalike domain registered nine days ago.
What changes the ending
- Wire changes verified by phone to a number on file from the day the matter opened, never to a number in the email (CIS 14 Security Awareness and Skills Training).
- Lookalike-domain and impersonation filtering on every mailbox, so the fake reply is flagged before a human has to catch it (CIS 9 Email and Web Browser Protections).
- Phishing-resistant MFA and new-country login alerts on every mailbox, so nobody sits inside your email for three weeks (CIS 6 Access Control Management).
