Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Arsenal Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall URL hijack to owhit.com — classic low-quality NewTab monetization shell behavior.
• Install URL hijack to owhit.com — opens 3rd-party page on install, indicative of traffic monetization.
• Privacy policy is Google's generic account policy (scope_extension=false, data_collection=true, 3rd-party sharing=true) — admits data collection without scoping to this extension.
• New-tab override combined with 'search' permission and gmail developer with no business domain — no accountability.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL points to https://owhit.com/uninstall — 3rd-party traffic monetization.
• install_url_hijack crx onInstalled opens https://owhit.com/arsenal-live-wallpaper — 3rd-party page on install.
• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new tab with extension content.
• 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 melikkaksoy01@gmail.com, no business domain, no verified publisher badge.
• js_external_hosts crx Extension references 8 external hosts including owhit.com, instagram, netflix, youtube, x.com — broad reach.
• search_permission_newtab_combo manifest 'search' permission + newtab override is a common search-monetization pattern.
• no_csp manifest content_security_policy is null; MV3 provides some defaults but no explicit CSP declared.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Arsenal Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.49 -> 7.99 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search behavior; medium risk on its own but combined with newtab override is concerning.
• chrome_url_overrides.newtab high Replaces new tab page — primary monetization vector for wallpaper/NewTab shells.
