Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Cyberpunk Girl Oni Mask Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override on a cosmetic wallpaper extension with search permission is a monetization shell pattern.
• Uninstall and install URL hijacks redirect users to gameograf.com with UTM tracking on every install/uninstall.
• No CSP declared (MV3 still requires explicit CSP for stricter coverage); innerHTML sinks present XSS risk.
• Developer name field empty; verified publisher discount partially offsets but identity accountability is reduced.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; every new tab hijacked by a wallpaper extension with search permission.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=extension&utm_medium=install
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=lofi&utm_medium=install
• no_csp manifest content_security_policy is null; csp_present == false with innerHTML sinks in popup.js and calendar.js.
• dom_sink_innerhtml crx Two innerHTML-from-variable sinks found in popup.js and calendar.js; DOM-XSS risk without CSP.
• verified_publisher store gameograf.com resolves, looks_throwaway=false, verified_publisher=true; partially mitigates reputation risk.
• privacy_policy_adequate api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true, third_party_silence=false.
• low_install_count store Only 51 installs; blast radius currently small but pattern matches gameograf cluster monetization shell.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Cyberpunk Girl Oni Mask Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 2.79 -> 5.29 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying the browser search service; paired with newtab override raises search-monetization concern.
• host_permissions: https://api.gameograf.com/* low Scoped to own API domain; low blast radius on its own.
• chrome_url_overrides.newtab high Replaces every new-tab page; high-reach, monetization surface, user sees developer content on every tab open.
