A junior sales clerk at BCD, a wholesale jewellers, received an email which appeared to be from a well known parcel delivery company informing her that a delivery had been attempted outside office hours and had consequently failed She was asked to click on a link and complete some seemingly innocent but logical questions to effect the delivery on the next day She thought no more about it but was very surprised the next month to be awarded salesperson of the month as her sales had doubled

Unfortunately, on investigation it was found that this was as a result of several fraudulent orders for high-value items that had seemingly been placed by an existing customer but delivered to a new address, which turned out to be a temporary box number The existing customer's credit card had been fraudulently charged for these orders

Which of the following types of cyber-attack had the sales clerk been a victim of?
