Understanding the Real Risks of Prompt Injection in AI Browsers

🔍 New AI Threat: Understanding PromptLock and Its Implications

ESET has recently unveiled a concerning vulnerability known as PromptLock, highlighting a new attack vector through prompt injection. This technique embeds hidden instructions in the DOM or metadata, allowing manipulation of AI behavior.

Key Insights:

• Nature of Threat: The actual risk hinges on the AI’s capabilities. At present, AI in browsers like Edge, Chrome, and Brave mostly reads and generates text. This presents the risk of:

  • Misleading outputs
  • Social engineering tactics

• Escalated Risks: If AI can access sensitive data (like passwords or API keys) or run scripts, the stakes rise significantly. However, most browser assistants are sandboxed, requiring user confirmation for actions.
