It used to be relatively easy to spot a scam call or message. But what happens when the person on the other end looks and sounds exactly like someone you trust? This technology, enabled by AI, is creating a much bigger problem for businesses, where a convincing face or voice could authorise a payment, unlock a system, or extract sensitive information.

We get into:

• The problem of deepfakes: How easy it is to fake and how hard it is to detect.

• The alarm bells: What signals should make an employee stop and verify who they're actually talking to on a call.

• The technology layer: What a system that detects deepfakes needs to be able to do, and how it can keep up with scammers operating on a global level.
