A convincing email, a real transfer: where fraud cover can differ
A practical review of impersonation, changed bank details, payment approval and financial-loss definitions, with a hypothetical scenario and a contract comparison framework.

The decision behind the headline
This review focuses on impersonation, changed bank details, payment approval and financial-loss definitions.
For the changed supplier account, examine both the message and the payment process. Was an existing mailbox compromised, a similar domain used or a real conversation intercepted? Those descriptions may matter to the investigation without automatically deciding coverage. Contact the bank promptly about possible recovery and preserve message headers, approval records and the original beneficiary details. An internal transfer instruction should not be rewritten after the event to make it appear unauthorised if it was actually approved through ordinary channels.
A hypothetical scenario to test
An accounts clerk receives a plausible supplier message and sends payment to a changed account. This is an invented example, not a reported claim or a promised payout. Reconstruct the sequence from the first sign of trouble to ordinary service resuming. Ask what would happen if the problem occurred during a holiday or at the busiest time of year. The stress test should expose assumptions about availability and timing before they are relied upon.
Build a prevention control around changes, not around an instruction to be careful. Verify bank details using a previously known contact, with a second approver for material transfers. Test a request arriving when the usual manager is away and the sender claims urgency. Ask the proposed insurer whether it addresses social-engineering transfers, technical compromise and crime losses through separate provisions. Compare the monetary sublimit with a plausible single supplier payment. A high general cyber limit can coexist with a much smaller fraud benefit. The business should know what it retains financially even when staff follow the documented approval process.
Identify the contractual boundary
A fraudulent instruction may exploit ordinary payment authority rather than damage a computer. That distinction is why a cyber product name does not settle transfer coverage. For a suspected transfer, contact your bank promptly about possible recovery and preserve the original message rather than only a screenshot.
Compare the wording, then the price
Use an identical scenario with each insurer and request clarification of social engineering extensions, voluntary transfers, crime-policy coordination and sublimits. Ask for the relevant clause and a written explanation of anything left uncertain. An optional extension should appear in the schedule, not merely in a sales discussion.
Reduce the exposure before transfer
A useful first action is to verify bank-detail changes using a known telephone number and separate payment duties. Assign an owner, a completion date and a simple test of whether the measure works. Written procedures matter only if staff can find and use them under pressure.
Evidence and the next review
Prepare original messages with headers, transfer confirmations, approval records and supplier contacts. Date the records and keep an accessible copy away from the affected process. Keep offline access to the insurer contact, incident plan and supplier escalation list. A claim notification does not replace any required regulatory notification. Review the arrangement when your activity, technology, locations or counterparties change.
