Fraud Detection for Healthcare AP Vendor Emails

The most expensive fraud in AP rarely looks like fraud. It looks like a routine email asking you to update a vendor's bank account. Here's how that attack works against healthcare AP teams and how automated verification stops it.

How bank change fraud targets healthcare AP

The attack is simple. A message arrives that looks like it came from a known vendor, saying their banking has changed and asking you to update the account on file before the next payment. If your team makes the change and the next payment goes out, it lands in the attacker's account, not the vendor's. By the time the real vendor calls about a missing payment, the money is gone.

These messages are convincing. They reference real invoices, use the vendor's branding, and often come from a lookalike domain or a compromised mailbox. The request itself is something your AP team does legitimately all the time, which is exactly why it slips through.

Why healthcare AP is particularly vulnerable

Healthcare AP carries a high vendor volume, so bank change requests are routine and a single fraudulent one is easy to miss in the flow. Staff turnover is common, which means the institutional memory that might catch an odd request ("that's not how this vendor usually contacts us") isn't always there.

Most of all, the entire process runs over email. Vendor communication arrives in a shared mailbox, requests get actioned by whoever picks them up, and verification depends on someone deciding to pick up the phone. When the work is busy and the request looks normal, that phone call doesn't always happen.

How automated detection works

Auxtri's Vendor Master Manager treats every bank change request as a controlled workflow rather than a quick edit. When a banking update arrives, Auxtri runs a domain mismatch check, comparing the sender against the vendor's known communication domains and flagging anything that doesn't line up.

The change then requires dual approval, so no single person can move a vendor's bank account alone. An out-of-band confirmation call to a number already on file (not a number from the request email) is logged as part of the record. While the change is being verified, Auxtri can apply a one-cycle payment hold so nothing pays out to an unconfirmed account.

Every step is audit-logged: the structured payload, the approver IDs, the confirmation reference, and the policy that fired. That record is built for compliance review from the start, not assembled after an incident.

It works the same way on every ERP

Because the controls live in the inbox layer, bank change verification works the same way whether you run Infor CloudSuite FSM, Workday Financial Management, Oracle Fusion Cloud Financials, or Oracle PeopleSoft. What changes is where the approved write lands once verification passes.

On Oracle Fusion, Auxtri's controls run on top of Oracle's native Supplier Bank Account approval. On Workday, Auxtri checks the Supplier Bank Account Review Status after the write. On Infor and PeopleSoft, Auxtri's dual approval and out-of-band confirmation are the primary protection on the change.
