Cybercriminals then use this technology to manipulate their targets through fake phone calls pretending to be someone they know.

It can also be used to bypass security systems.

This technology was used in a 2024 heist in which $25 million was stolen by thieves using AI to impersonate a company’s CFO in a video call. 

According to Ebrahim, Microsoft’s AI can mimic a voice after just three seconds of audio.

“The delivery is so closely replicated that you cannot tell.”

She says that hundreds of tests have been conducted on AI tools and 80% of the time they produced convincing cloned voices.

Using these tools, they generated realistic voice clones of political figures urging people not to vote or alleging fraud. 

“We are leaning more towards the negative than the positive.”
