One account takeover in fraud case management, from four alerts to a signed close
Ridgeline Auto Body LLC, a business customer of Corvane National Bank in Sandusky, Ohio, since 2017. On October 13 someone resets the owner's digital banking password from a new Android phone, changes the mobile number, deposits a check and sends a $48,600.00 wire to a new payee. Here is the case, screen by screen, in the working solution.
- 01October 13 to 15
Four alerts from two engines become one case
Intake agentThe payments fraud engine raises PF-88231407 on the wire to a new payee, PF-88231409 on the same wire from a velocity rule, and PF-88233952 on a $9,800.00 ACH debit from an originator never seen on the account. Two days later the check and deposit fraud engine raises CD-55104218: check #1182 came back counterfeit. The intake agent joins them into case FC-2026-18342 at confidence 0.97, same customer and same device inside 72 hours, and drops the second wire alert with its reason.
PF-88231409: “The same wire, velocity rule”, dropped as a duplicate and kept visible with Restore.
- 02Wednesday morning
The case opens as a binder
Marisa Delgado · Fraud InvestigatorMarisa opens the binder: nine evidence tabs on the left, each saying in one line what the agent took from it. The device log tab reads: “A new Android phone at 6:44 AM; the number changed at 6:47; a wire payee added at 7:03.” In the center is the drafted decision memo, 17 sentences, 17 cited, confidence 0.93, proposing confirmed third-party fraud and a $22,300.00 reimbursement.
“Marisa Delgado decides · Supervisor approves · up to $50,000.”
- 03Before she reads
How the agents built the binder
The agentsThe Agents tab shows each step: the intake agent's merge, the redaction agent masking every number to the last four, the evidence agent pulling nine sources, the recovery agent's $38,900.00 recovered, the drafting agent's 17 cited sentences under decision code FD-ATO-2, and the clock agent's due date of Thursday, October 22.
“Agents never close a case, move money, post to the ledger, contact the customer or file a SAR.”

The counterfeit check, with what the agent found pinned on it
Evidence agentCheck #1182 from “Brayfield Insurance Agency”, $2,800.00, deposited from the new phone at 6:52 AM. The check image tab shows the front and back with three callouts: the serial is outside the maker's range of 4410 to 4630, the amount and date font, and no “for mobile deposit only” restriction on the back. Returned unpaid on October 15: counterfeit, refer to maker.
- 05A question
She asks the binder why the payee hold did not apply
Marisa Delgado · Fraud InvestigatorBank standard OBS-7 holds new payees for 24 hours after a mobile number change. Marisa asks whether the hold was applied, and the answer comes with its passages: release 26.07 attached the hold only to the security settings page, so a change on the profile page did not start it.
A question the binder cannot answer gets “I will not guess”, not an invention.
- 06The three numbers
Loss, recovered and outstanding, to the cent
Recovery agentLoss $61,200.00: the wire, the ACH debit and the counterfeit deposit. Recovered $38,900.00: $29,100.00 returned on the wire recall and $9,800.00 on the R29 return. Outstanding $22,300.00. The recovery agent drafts two general ledger entries to fraud losses, JE-1 for $19,500.00 and JE-2 for $2,800.00, which Marisa proposes; nothing posts yet.
- 07Send for approval
A sentence that rests on a guess is challenged
Quality agentWhen Marisa sends the case, the quality agent reads every sentence against its source. Sentence 4, “The owner clicked a phishing link in an email on October 12”, rests only on the owner's own belief in the call transcript; no mail header or provider record is in the binder. Support 0.58, under the 0.70 threshold. The amounts tie and the decision code fits.
Suggested: “The owner believes she typed her password on a fake mailbox page on October 12; how the mailbox was compromised is not confirmed.”
- 08One edit, then approve
The supervisor accepts the fix and approves the close
Curtis Ambrose · Fraud Investigations SupervisorCurtis accepts the suggested wording, which is marked as his edit, then approves the close, the reimbursement and both ledger entries in one step. Net loss $22,300.00 is inside his $50,000 limit. Marisa made them, Curtis checks them, and neither can do both.
“Maker: Marisa Delgado · checker: Curtis Ambrose · net loss $22,300.00, inside your $50,000 limit.”
- 09Kept apart
The SAR referral stays with BSA
Referral agentThe total of $61,200.00 is over the $25,000 threshold, so on October 15 the referral agent sent referral RF-26-0913 to the restricted BSA space. The fraud case keeps only the reference. Whether a report is filed, and the BSA officer's notes, never appear in the case, a customer letter, a customer view or a fraud export.

Every step on the audit trail, and an examiner pack
Wendell Osei · Internal AuditorThe trail shows who did what, when, why and on what evidence, people and agents alike: the challenge, the accepted wording, the approval and the posting. An examiner pack for the OCC on Q3 2026 account takeover cases is built in one step: 61 cases and 1,412 pages, masked to the last four, with referral material excluded.
