Perfect Wiki AIExample answer

A vendor just emailed new banking details for an upcoming payment. Can I update them right away?

No. Verify any change to banking details through a secondary contact method, such as a phone call to a known contact, before updating the vendor record, since email requests for banking changes are a common fraud pattern.Source: step 5.3 ยท Verify tax and banking information
