Meredith Whittaker, president of Signal, expresses strong concerns about the rise of AI agents, describing them as an “existential threat” to secure messaging platforms and app developers. AI agents require access to sensitive information, creating new vulnerabilities that can be exploited by cybercriminals. Whittaker points out the risk of prompt injection attacks, which can manipulate AI to execute harmful actions, leading to data breaches. She argues that unrestricted access to user communications by AI agents poses a significant risk to privacy and security, undermining the foundational security of the internet. Whittaker criticizes the reckless implementation of AI by Big Tech companies, suggesting it compromises cybersecurity in favor of rapid deployment and financial pressures.
