Top Risks

  • Default search engine overridden to search.searchsafe.tech; uninstall and install URL hijacks confirmed — classic monetization shell.
  • No developer name listed despite verified-publisher badge; accountability gap.
  • Privacy policy admits data collection and third-party sharing but lacks retention disclosure.
  • Uninstall/install URL hijacks both present; typical pattern for traffic-redirect extensions.
  • Maintenance gap of 13 months (6-12mo band) raises supply-chain staleness concern.

Evidence

  • search_provider_override manifest chrome_settings_overrides sets is_default=true to search.searchsafe.tech — forced search hijack.
  • uninstall_url_hijack crx uninstall_url_hijack=true; target null but pattern confirmed — webstore signal +3.0.
  • install_url_hijack crx install_url_hijack=true; onInstalled opens 3rd-party URL — webstore signal +2.0.
  • verified_publisher_featured store Verified publisher + featured badge present; discounts applied but capped due to stale/hijack signals.
  • no_developer_name store developer_name is empty string despite verified publisher status.
  • privacy_policy_third_party_sharing api Policy fetched; scope_extension=true, data_collection=true, third_party_sharing=true, retention=false.
  • js_external_hosts crx Extension contacts github.com and search.searchsafe.tech as external JS hosts.
  • maintenance_stale store 13 months since last update; falls in 12-24mo band (+6.0 maintenance score).

Permissions Breakdown

  • storage low Persists settings locally; minimal risk on its own.
  • chrome_settings_overrides.search_provider (is_default=true) high Silently replaces user's default search engine with searchsafe.tech — core monetization vector.
