  4. Employ endpoint security solutions that monitor and restrict unauthorized file access by browser extensions.
  5. Regularly audit installed extensions and remove any that are unnecessary or suspicious.
  6. Use enterprise management tools to enforce extension whitelisting and prevent sideloading of unapproved extensions.
  7. Monitor network and system logs for unusual file access patterns that may indicate exploitation attempts.
