That's according to a new report from McAfee's Artificial Intelligence for Cybersecurity. Artificial intelligence is accelerating a multibillion-dollar global criminal scheme - "imposter scams". Using AI technology, scammers can clone the voices of relatives, friends, and even children, and call victims with fake emergencies. Last year, such imposter scams cost $2.6 billion. To guard against this type of scam, McAfee recommends setting a password with children, family members, or trusted friends that only they know, and establishing a set of rules to ensure that it is always asked for when calling for help.
