Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Hollow Knight Silksong Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL both hijack to gameograf.com with UTM tracking — classic traffic monetization shell.
• NewTab override combined with 'search' permission replaces every new tab for ad/monetization benefit.
• Privacy policy is Google's generic account policy — entirely unscoped to this extension; admits data collection + third-party sharing.
• Free-webmail developer (gmail) with no verified identity or business website.

Evidence

• uninstall_url_hijack manifest chrome.runtime.setUninstallURL targets gameograf.com with ovkas UTM params — 3rd-party redirect on uninstall.
• install_url_hijack manifest onInstalled opens gameograf.com with ovkas UTM params — traffic monetization on install.
• newtab_override manifest chrome_url_overrides.newtab = index.html; every new tab served by extension.
• privacy_policy_generic store Policy URL is Google account policy (scope_extension=false, data_collection=true, third_party_sharing=true).
• free_webmail_dev store Developer email halilseker3455@gmail.com — no verified business, numbered-alias pattern.
• js_external_hosts crx Extension JS contacts gameograf.com, instagram.com, netflix.com, youtube.com, x.com — 6 distinct domains.
• search_permission_newtab_combo manifest 'search' permission + newtab override is standard search-monetization pattern.
• no_csp manifest content_security_policy is null; MV3 defaults apply but no explicit restriction on outbound connections.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Hollow Knight Silksong Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 6.10 -> 8.60 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search; combined with newtab override this is a monetization surface.
• chrome_url_overrides.newtab high Replaces every new tab with extension-controlled page; primary vector for traffic monetization.
