  • Engineer — Plan: Audit installed Chrome/Edge extensions across your managed fleet and enforce an allowlist policy; no CISA KEV or active enterprise exploitation signal, but browser extension supply-chain risk is real for developer workstations.
  • SOC/IR — Act: Hunt for suspicious extension IDs from the reported malicious set in browser inventory logs and EDR telemetry; also look for ClickFix lure behavior (fake captcha/update prompts triggering clipboard/PowerShell execution) as a detection pattern since this reporting date.
  • Leader — Plan: Browser extension governance is a gap in most enterprise policies — use this as a prompt to task the team with drafting an approved-extension policy before the next audit cycle.
