AI Chatbots and Privacy: Lessons from the Urban VPN Case
AI Chatbot Security and privacy are becoming a critical issue for those who use AI tools in their daily work. AI chatbots are increasingly integrated into marketing, customer support, and automation workflows, but recent events show that the security risks are far from theoretical.
Researchers at Koi Security have discovered that eight extensions for Google Chrome and Microsoft Edge were able to intercept and capture users' conversations with AI chatbot The most notable case involves Urban VPN Proxy, a free VPN with millions of downloads, which had an AI chat exfiltration feature integrated into its code that could not be disabled.
AI Chatbots Under Observation: What Researchers Discovered
According to the analysis published on the official Koi Security blog, the research team used a dedicated tool to inspect the behavior of Urban VPN Proxy. It turned out that the extension can access conversations with several AI chatbot: ChatGPT, Copilot, Claude, Gemini, DeepSeek, Perplexity, Grok and Meta AI.
This feature is built directly into the extension's code and there's no option to disable it. The free VPN Urban VPN Proxy is very popular in the Google Chrome store, with over 6 million downloads, making the issue particularly relevant in terms of scale and potential impact on business users.
According to Koi Security, chat exfiltration was introduced in early July with version 5 of the extension. Urban VPN Proxy effectively accesses conversations even when it's apparently not running, a behavior that further increases the privacy risk.
How Extensions Access Conversations with AI Chatbots
The mechanism identified by the researchers is technically simple but very effective. The extension continuously monitors the open tabs in the browser and, when the user accesses the web version of one of the AI chatbot listed, injects a JavaScript code into the page.
This script intercepts both user-entered prompts and the AI chatbot's responses, creating a complete log of the conversations. All this data is then sent to remote servers controlled by the developer. In practice, every interaction with the AI chatbot can be visible to third parties without the user's knowledge.
The Urban VPN Proxy extension page in the Chrome Web Store describes a feature called AI Protection. When the user enters personal data, such as email addresses, phone numbers, or other sensitive information into the prompt, the extension displays a warning about the risk of sharing.
At the same time, however, Urban VPN Proxy sends the same data to the servers of the developer, Urban Cyber Security, based in Delaware. This raises significant concerns not only about privacy, but also about the transparency of the information provided to users, especially those who use the services on a daily basis. AI chatbot in the corporate environment.
Other extensions involved and privacy implications
Koi Security has highlighted that the same code for monitoring conversations with AI chatbot It's also present in the Microsoft Edge version of the extension. Furthermore, the offending code has been found in three other extensions from the same developer for Chrome and Edge.
The additional extensions listed are: 1ClickVPN Proxy, Urban Browser Guard, and Urban Ad Blocker. Adding all supported variants and browsers, the total comes to eight extensions potentially capable of collecting conversations with AI chatbots. This significantly expands the attack surface and the number of affected users.
The Urban VPN Proxy page in the Chrome Web Store states that the extension only analyzes browsing history and that the data is not sold to third parties. However, there is no explicit reference to AI conversation collection or prompt content analysis.
Chat collection occurs even when the VPN is disconnected or when the AI Protection feature is disabled. In practice, the user may believe they are protected or not being monitored, while the extension continues to intercept interactions with users. AI chatbot. For this reason, Koi Security recommends that frequent users of AI chatbots immediately uninstall all listed extensions.
The Urban VPN case is part of a broader picture of risks related to online privacy and the use of non-transparent browser extensions. Organizations such as the Electronic Frontier Foundation (EFF) and authorities such as the Guarantor for the protection of personal data (Privacy Guarantor) have been stressing for years the importance of carefully evaluating the permissions granted to extensions, especially when handling sensitive data.
