A deepfake scam is a fraud committed with the help of synthetic media: audio, video or images generated or altered by software so that a person appears to say or do something they did not. The commonest financial forms are a cloned voice on a telephone call, a fabricated video of a public figure endorsing an investment, and a manufactured face and voice in a live video meeting.
The most useful thing to understand about the category is that it is not really a category. The FBI's Internet Crime Complaint Center, which classifies every complaint it receives, does not have a deepfake crime type or a voice-cloning crime type. It handles artificial intelligence as a descriptor, a separate field from the crime type, and defines the concept in one sentence: "A Descriptor relates to the medium or tool used to facilitate crime and is used by IC3 for tracking purposes only. It is available as a descriptor only after a crime type has been selected." There are three descriptors in the system, and AI Related is one of them. The crime type has to be chosen first, and each complaint carries only one.
That architecture is the thesis of this page. Synthetic media is how a scheme is executed, not what the scheme is. A cloned voice used to demand a wire from a company is business email compromise. A cloned voice used to say a grandchild is in trouble is a family emergency scam, covered on our page about the grandparent scam. A fabricated video of a chief executive promoting a token is investment fraud. The technology raises the quality of the performance; it does not create a new offense or a new set of defenses.
A note on naming, and on a distinction this page declines to make. There is no single official name for the merged concept. "Deepfake scam" is the phrasing used in the title of a joint infographic from the American Bankers Association Foundation and the FBI, which the FBI lists in its own annual report, and it is the phrase most readers search. Whether a voice clone is best described as a species of deepfake or as a separate thing is genuinely unsettled in official usage: the FTC's own material about its Voice Cloning Challenge describes a submission that would "detect in real time voice cloning and deep fakes," naming them as two. This page treats both as synthetic media used as a medium and does not rule on the taxonomy.
