Imagine your company's AI assistant crawling through a seemingly innocuous website only to be manipulated into revealing sensitive information or generating malicious code. Researchers demonstrated exactly this vulnerability with ChatGPT's search tool. They showed how hidden text on webpages could override the AI's judgment and make it produce deceptively positive reviews despite visible negative content on the same page. Similarly, security experts revealed how Microsoft's Copilot AI could be transformed into an automated phishing machine. These attacks are particularly dangerous because they exploit the AI systems exactly as designed—using text inputs to manipulate their behavior rather than breaking underlying code. As language models become more deeply integrated into business operations, the risk of manipulation through carefully crafted text inputs increases proportionally. This article explores how to understand, prevent, and mitigate the risk of manipulation and text-based exploits in your AI applications.
