Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Michael Kaiser Blue Lock Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall URL hijack to owhit.com — classic monetization shell telemetry/tracking signal.
• Install URL hijack to owhit.com — third-party onboarding redirect on every fresh install.
• Privacy policy is generic Google account policy, not scoped to this extension; admits data collection and 3rd-party sharing.
• NewTab override with 'search' permission enables search-provider manipulation on every new tab.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL points to https://owhit.com/uninstall — third-party monetization/tracking endpoint.
• install_url_hijack crx onInstalled opens https://owhit.com/michael-kaiser-blue-lock-wallpaper — third-party redirect on install.
• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new tab for all users.
• privacy_policy_generic store Policy URL is Google account policy (myaccount.google.com); scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_developer store Developer email kaansefa83@gmail.com; no verified publisher badge; no business domain.
• js_external_hosts crx Extension contacts chatgpt.com, owhit.com, instagram.com, x.com, youtube.com — 7 external hosts, 2 countries.
• search_permission_newtab_combo manifest 'search' permission + newtab override = capable of search-provider manipulation without chrome_settings_overrides.
• no_csp manifest content_security_policy is null (csp_present=false); MV3 default applies but no explicit hardening declared.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Michael Kaiser Blue Lock Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.43 -> 7.93 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/manipulating search queries; paired with newtab override amplifies search-hijack risk.
• chrome_url_overrides.newtab high Replaces every new tab; primary vector for ad-monetization and search redirect for NewTab shells.
