Unmanaged Extensions: Third-Party Risks Running Rampant

Browser extensions pose the same risks as any unmanaged third-party code running in your organization. Unfortunately, businesses have near-zero visibility into these lightweight, privileged add-ons that run on nearly every employee’s machine. Attackers know the browser interface is often unmanaged and take advantage of this common oversight.

‍

Browser extensions can read user input, exfiltrate sensitive data, steal credentials, disable other add-ons, and gather reconnaissance for future attacks. Many are installed without IT approval. Some are overly permissive. A few are outright malicious. And the good ones? They can be compromised without warning.

‍

If you or your team are wondering:

• “How do browser extensions present risk to our business?”
• “What add-ons are installed across my organization?”
• “Which of these have dangerous permissions or are otherwise risky?” 
• “How can we swiftly detect and respond to a compromised extension?”
  
  

Then this guide will answer your questions and get your team on the right track.
