On December 18, 2025, Anthropic released the beta version of its Claude Chrome extension, a tool that lets the AI browse and interact with websites on your behalf. While convenient, a new analysis from Zenity Labs shows it introduces a serious set of security risks that traditional web protections weren\u2019t designed to handle.<\/p>\n

Breaking the Human-Only Security Model<\/p>\n

Web security has mostly assumed there\u2019s a person behind the screen. When you log into your email or bank, the browser treats the clicks and keystrokes as yours. Now, tools like Claude can click, type, and navigate sites for you. <\/p>\n

Researchers Raul Klugman-Onitza and Jo\u00e3o Donato noted that the extension stays logged in at all times, with no way to disable it. That means Claude inherits your digital identity, including access to Google Drive, Slack, or other private tools, and can act without your input.<\/p>\n

How the Claude Chrome extension works<\/p>\n

The Lethal Trifecta of AI Risks<\/p>\n

Zenity Labs\u2019 technical blog post shows the company flagged three overlapping concerns: the AI can access personal data, it can act on it, and it can be influenced by content from the web.<\/p>\n

This opens the door to attacks like Indirect Prompt Injection, where malicious instructions are hidden in webpages or images. Because the AI uses your credentials, it can carry out harmful actions like deleting inboxes or files, or sending internal messages without your knowledge. Attackers could also move laterally inside a company by hijacking the AI\u2019s access to services like Slack or Jira.<\/p>\n

In technical tests, researchers showed that Claude could read web requests and console logs, which can expose sensitive data like OAuth tokens. They also demonstrated how Claude could be tricked into running JavaScript, turning it into what the team called \u201cXSS-as-a-service.\u201d<\/p>\n

Why Safety Switches Aren\u2019t Enough<\/p>\n

Anthropic did include a safety switch called \u201cAsk before acting,\u201d which requires the user to approve a plan before the AI takes a step. However, Zenity Labs\u2019 researchers found this to be a \u201csoft guardrail.\u201d In one test, they observed that Claude ended up going to Wikipedia even though it was not in the approved plan. This suggests the AI can sometimes drift from its path.<\/p>\n

Researchers also warned of \u201capproval fatigue,\u201d where users get so used to clicking \u201cOK\u201d that they stop checking what the AI is actually doing. For real-world organisations, this isn\u2019t just a sci-fi worry; it\u2019s a fundamental change in how we must protect our data.<\/p>\n
