77 Open VSX extensions caught harvesting developer environment data

  • Engineer — Act: If your team uses Open VSX (common in VS Code OSS or VSCodium environments), audit installed extensions against the removed list and purge any matches; review extension installation policies in CI/CD or dev container configs to restrict to known-good sources.
  • SOC/IR — Plan: Build or tune detections for unexpected outbound connections from IDE processes (code, codium) to unknown endpoints; consider hunting for extension-related network activity in EDR telemetry from developer workstations over the past 90 days.
  • Leader — Learn: This incident illustrates ongoing supply-chain risk in developer tooling marketplaces; useful context for evaluating software vetting policies in engineering onboarding, but no immediate leadership action required.
