Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Toyota Supra Neon Rainy Tokyo Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall URL hijack to gameograf.com game-portal with UTM tracking — classic monetization shell.
• Install URL hijack to same gameograf.com — opens 3rd-party on install.
• Privacy policy is Google's own policy (scope_extension=false, data_collection=true, third_party_sharing=true) — generic, admits broad sharing, not scoped to this extension.
• NewTab override combined with search permission and free-webmail dev = high redirect/monetization risk.
