Berkshire Hathaway has issued a warning about AI-generated deepfake videos featuring Warren Buffett, which are being used to promote fake investment advice. These videos, circulating on platforms like YouTube, employ advanced AI technology to convincingly mimic Buffett's voice and appearance, misleading viewers into believing the content is genuine. The company stressed that only the real Warren Buffett speaks for himself and advised the public to verify the authenticity of such content through official channels. Cybersecurity reports highlight a 33% increase in financial fraud losses from AI-related scams last year, totaling $16.6 billion.
