The rapid advancement of deepfake technology, driven by sophisticated artificial intelligence algorithms such as Generative Adversarial Networks (GANs), has introduced unprecedented challenges to business practices, particularly within the G7 nations. Deepfakes—hyper-realistic digital forgeries of audio, video, and imagery—have the potential to undermine corporate integrity, erode public trust, and destabilize financial markets. This study explores the legal and ethical implications of deepfakes, with a focus on their disruptive impact on business operations in these technologically advanced countries. Through a comprehensive literature review, secondary data analysis, and case studies, the research identifies the key risks associated with deepfakes, including fraud, defamation, and misinformation. It critically examines existing regulatory frameworks, highlighting the insufficiency of current laws to address the complex realities of digital impersonation and identity theft. Furthermore, the ethical concerns surrounding the manipulation of corporate communications and consumer perception are explored, emphasizing the necessity for enhanced transparency and accountability in business practices. The study concludes by advocating for the development of robust international legal standards, advanced cybersecurity protocols, and ethical guidelines to mitigate the risks posed by deepfake technology. As deepfakes continue to evolve, businesses must adapt to an increasingly uncertain digital environment, balancing innovation with responsibility to maintain credibility, trust, and security.
