Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Marvel Rivals Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall URL hijack to owhit.com — classic traffic-monetization shell pattern.
• Install URL hijack to owhit.com — tracks installs via third-party domain.
• Privacy policy is Google's generic policy, not scoped to this extension; admits data collection and 3rd-party sharing.
• New-tab override + search permission enables search-traffic redirect monetization.

Evidence

• uninstall_url_hijack manifest chrome.runtime.setUninstallURL points to https://owhit.com/uninstall — 3rd-party traffic capture.
• install_url_hijack manifest onInstalled opens https://owhit.com/marvel-rivals-live-wallpaper — 3rd-party domain on install.
• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new-tab page for all users.
• generic_privacy_policy store Privacy URL is Google's account policy (scope_extension=false, data_collection=true, third_party_sharing=true).
• free_webmail_developer store Developer email orhanyildizsd@gmail.com; no verified publisher badge; no business domain.
• external_hosts crx JS references owhit.com, chat.openai.com, instagram.com, netflix.com, x.com — broad unrelated origins.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening declared.
• search_permission_newtab manifest Combined search permission + newtab override typical of search-monetization shells.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Marvel Rivals Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.43 -> 7.93 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search provider; medium risk in context of newtab override.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary monetization surface for traffic-hijack shells.
