Top Risks

• Uninstall URL hijack to owhit.com — confirmed traffic-monetization shell pattern.
• Install URL hijack to owhit.com — opens 3rd-party page on every install.
• NewTab override replaces every new tab; combined with 'search' permission enables ad-search monetization.
• Privacy policy is Google's generic account policy — has no scope to this extension despite admitting data collection and 3rd-party sharing.
• Free-webmail developer (gmail) with no verified identity or business website; dev name 'playgames' mismatches calendar/wallpaper category.

Evidence

• uninstall_url_hijack manifest chrome.runtime.setUninstallURL → https://owhit.com/uninstall; classic monetization shell redirect.
• install_url_hijack manifest onInstalled opens https://owhit.com/september-2026-calendar-wallpaper on every install.
• newtab_override manifest chrome_url_overrides.newtab = index.html — controls every new tab for all users.
• privacy_policy_generic store Policy URL is Google account privacy page; scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_developer store Developer email yakupogluokul@gmail.com; dev name 'playgames'; no verified publisher badge.
• js_external_hosts_broad crx Extension references 7 external hosts including chatgpt.com, instagram.com, x.com — unrelated to calendar/wallpaper function.
• search_permission_plus_newtab manifest 'search' permission combined with newtab override matches ad-monetization aggregator fingerprint.
• category_mismatch_devname store Developer name 'playgames'; extension titled calendar wallpaper — functional mismatch raises cloaking concern.

Permissions Breakdown

• search medium Allows overriding default search; paired with newtab override amplifies search monetization risk.
• chrome_url_overrides.newtab high Replaces every new tab — high-reach persistent surface for monetization and tracking.
