With just 15 seconds of audio, hackers can now launch convincing deepfake scams—targeting CEOs, employees, and even world leaders.

The US State Department said it is investigating an imposter who used artificial intelligence to impersonate Secretary of State Marco Rubio and contact three foreign ministers.The "unknown actor" is alleged to have used an artificially-generated voice of Rubio to contact officials via the Signal messaging app,

Rubio said he was unable to provide a date for any potential meeting but said there was a “strong desire on both sides to do it.”
