According to Andrej Karpathy on Twitter, prompt injection attacks targeting large language models (LLMs) are emerging as a major security threat, drawing parallels to the early days of computer viruses. Karpathy highlights that malicious prompts, often embedded within web data or integrated tools, can manipulate AI outputs, posing significant risks for enterprises deploying AI-driven solutions. The lack of mature defenses, such as robust antivirus-like protections for LLMs, exposes businesses to vulnerabilities in automated workflows, customer service bots, and data processing applications. Addressing this threat presents opportunities for cybersecurity firms and AI platform providers to develop specialized LLM security tools and compliance frameworks, as the AI industry seeks scalable solutions to ensure trust and reliability in generative AI products (source: Andrej Karpathy, Twitter, June 16, 2025).
