Shadow AI in the Browser: The Next Enterprise Blind Spot

Shadow AI in the Browser: The Next Enterprise Blind Spot

Shadow AI refers to GenAI-powered tools, browser extensions, and agentic browsers that run inside the browser, creating an unmanaged AI execution environment with security visibility gaps. The article outlines six risks, a real-world Perplexity Comet Attack example, and recommended defenses such as browser session monitoring, clear AI-use policies, identity controls, and employee education. #ShadowAI #PerplexityCometAttack

Keypoints

  • Shadow AI runs GenAI tools and agentic browsers inside the browser, creating an unmanaged execution environment beyond traditional controls.
  • AI-powered extensions can gain elevated permissions and exfiltrate data without visibility to legacy security tools.
  • Indirect prompt injection lets the AI read hidden instructions in web content and act across domains with user authority.
  • AI agents inside the browser can expose identity artifacts like session cookies and tokens, enabling persistent access if leaked.
  • BYOD and automated AI updates create supply-chain and governance gaps, increasing risk and reducing security visibility.
