One held wire, from the hold to the stop in 25 minutes
Thursday, October 22, 4:22 PM at Corvane National Bank, 38 minutes before the 5:00 PM Fedwire client cutoff. Here is wire fraud prevention on one business email compromise attempt, screen by screen, in the working solution.

The day in one sentence, on a runway to each cutoff
Leah Okonkwo · Wire room operatorCorvane has sent 4,912 outgoing wires worth $10.38 billion so far. The agents held 248; 211 were released after review, 3 attempts were stopped ($1,256,200) and 34 held wires are open. The cutoff runway shows 23 minutes to the 4:45 PM CHIPS client cutoff and 38 to the 5:00 PM Fedwire client cutoff, and Leah's held wires are grouped by cutoff, each with the agents' finding and proposal.
Cleared by the agents: 4 wires, $1,974,950, ready to release in one batch with a second name.

What changed: a new bank, after 11 payments to the old one
Payment history agentBrightwater Mechanical, Inc. is wiring $286,400.00 by Fedwire to its steel supplier, Kessler Steel Supply Co., for invoice KS-22817. Gina Marsh entered it at 4:11 PM and Carl Lindqvist, the CFO, approved it with his token at 4:16 PM. The agent sets the last 11 payments to Kessler, all to Quillfield Bank, account ending 4471, beside today's instruction: Harrowgate Savings Bank in Houston, account ending 9086. Every value opens its source passage.
3 of 6 fields changed. The name and address are unchanged, and the amount is inside the $41,200–$312,900 range.

The email Gina acted on, read letter by letter
Instruction origin agentThe new bank came from an emailed PDF Gina uploaded at 3:47 PM. The email is a reply inside the real invoice thread, but it came from kesslersteeI.com: a capital I (U+0049) where Kessler's domain has a lower-case l (U+006C), registered October 13, 2026, nine days ago. Replies go to kessler.remit@inbox-relay.net, and SPF and DKIM pass only for the look-alike domain.
The attached letter was created October 21 at 11:52 PM on Kessler's 2023 letterhead, with a Houston phone number and the ongoing-audit wording.
- 04Before the call
A callback to a number of known origin, never the one in the email
Callback agentThe agent takes Kessler's number, (412) 555-0187, from Brightwater's beneficiary template, on file since March 9, 2021 and reconfirmed in April 2025. The PDF's number, (713) 555-0164, is struck out and never offered. The five-line script asks Kessler to state its own bank and account.
From the script: “Never read the new bank or account out. Never confirm the amount first.”

Leah makes the call; the agent fills in the result
Leah Okonkwo · Wire room operatorOn the recorded line, Janet Pruitt, Kessler's controller, says Kessler still banks at Quillfield Bank, account ending 4471, and sent no change of bank details. The callback agent fills each answer from the recording, and Leah checks and confirms it. At 4:35 PM she calls Carl Lindqvist at Brightwater's number on file, and he asks Corvane to cancel.
Outcome: “Not confirmed: the beneficiary denies the change.”
- 064:41 PM
Stopped with two names, 19 minutes before the cutoff
Leah Okonkwo and Victor HaleLeah proposes Stop at 4:39 PM with reason SR-01, beneficiary denies the change (vendor impersonation). Victor Hale, the wire room supervisor, adds the second name at 4:41 PM. At $250,000 and above the second name must be a supervisor, and nobody checks their own decision. The $286,400.00 never left.
The order passed Brightwater's token and dual approval under UCC 4A-202. That proves who sent it, not that the bank details are Kessler's.
- 074:44 PM
The client is told in plain words, with no blame
Nadia Brennan · Relationship managerThe recall agent drafts the message to Carl and Gina: what happened, what Corvane did and what to do now. Pay Kessler with the existing Quillfield template, reset Gina's email password and turn on two-step sign-in, and call Janet at (412) 555-0187. Nadia approves the message, Victor checks it, and only then does it go.
Checked before it goes: no SAR, referral, case number or investigation wording, and no account number in full.
- 084:46 PM
A fraud case with the evidence attached, and a confidential referral
Owen Castellanos · Fraud analystThe stopped attempt becomes fraud case FC-2026-1187, with the timeline from the 4:16 PM hold to the stop and the evidence already attached: the payment history, the email header, the domain lookup, the PDF and both recordings. The case and referral agent drafts the referral to the BSA team: attempted transactions are reportable, $286,400 is over $25,000 with no suspect identified, and the SAR is due by November 21, 2026. The fraud analyst approves the referral and a supervisor adds the second name.
The referral is visible to fraud, supervisor and audit roles only, never on a client view.
- 09The template
The bank change behind it is blocked too
Victor Hale · Wire room supervisorBrightwater's portal request at 4:12 PM to move Kessler's template to Harrowgate Savings Bank, change BC-2210, is blocked: Janet Pruitt denied it at the number on file, and it is linked to the stopped wire. Every beneficiary change needs a callback at a number of known origin and two names.
Numbers of known origin cannot be changed by email or by the client alone.

Every step on the record, exported for examiners
Ruth Ambler · Internal auditorThe trail shows who held, called, proposed, checked, stopped and told the client, when, why and on which evidence, for people and agents alike, and nothing in it can be edited. For a client dispute, Ruth exports the payment order, the security procedure followed, the email and PDF, both recordings, the stop with both names and the client message. The export itself is logged.
Exports for OCC examiners, internal audit, a client dispute and the BSA officer.
