Title: Put Words In My Mouth

Abstract: 
Money has been withdrawn from your account.
You don’t remember making, or authorising that transaction.

When you follow up with the bank, they say you called earlier and requested the transfer – it was, after-all, you speaking – right? Unbeknownst to you, your voice was stolen, and so was your money.

With the rise of voice authentication biometrics, so will the opportunities to spoof it. Text-to-Speech API’s are constantly improving, with Google’s technology now being indistinguishable from the real human speaker.

Threat actors have access to a target’s YouTube videos, social media posts. Even more invasive channels are certain vulnerable IoT devices, littered throughout homes and offices. Social media posts and IoT’s allow threat actors to listen to your voice, capture and then manipulate it (all using free online tools).


So what exactly can be done with a ‘stolen’ voice? This research explores the possibilities of fraud, by using voice-spoofing to bypass authentication.
