Deepfakes are becoming more common and cybercriminals are using them to steal private information and trick you into sending money to fake accounts. Here’s how to protect yourself against this type of scam.
A deepfake is a video, image or audio file that has been altered to impersonating someone. With artificial intelligence (AI), criminals can copy a person’s face or voice to make it seem like someone is saying or doing something they didn’t actually do.
At first, deepfakes were just for fun, but today scammers are using them to target people and businesses.
To explain the danger of deepfakes, we’ve chosen a very popular impersonation case, the tale of Little Red Riding Hood, where the “wolf” pretends to be the grandma. Today’s “wolves” are no longer in the forest. They’re on your devices, using videos and calls that look and sound real to impersonate someone you trust, such as a family member or your bank.
Deepfake Types
Voice cloning
AI can copy someone’s voice from a short recording and make it sound like a family member, a friend or someone you work with.
Lip sync
The movement of someone’s lips can be changed to match a different sound, so they can use a real video to deliver a fake message.
Face swap
AI can swap faces in a photo or video, even live during a call. This can make you believe you’re talking to the real person.
