According to Andrej Karpathy on Twitter, prompt injection attacks targeting large language models (LLMs) are emerging as a major cybersecurity concern in 2025, reminiscent of the early days of computer viruses. Karpathy highlights that malicious prompts hidden in web data and tools lack robust defenses, increasing vulnerability for AI-integrated platforms. For crypto traders, this raises urgent concerns about the security of AI-driven trading bots and DeFi platforms, as prompt injection could lead to unauthorized transactions or data breaches. Traders should closely monitor their AI-powered tools and ensure rigorous security protocols are in place, as the lack of mature 'antivirus' solutions for LLMs could impact the integrity of crypto operations.
