Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — May And Kyogre Pokemon Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy (scope_extension=false, admits data_collection+third_party_sharing) — scores maximum 10.0.
• Uninstall and install URL hijacks redirect to gameograf.com tracking URLs — classic monetization shell pattern.
• New-tab override replaces browser homepage; combined with 'search' permission creates search monetization surface.
• Two innerHTML DOM-XSS sinks with no CSP present; MV3 default helps but no explicit policy declared.

Evidence

• privacy_policy_generic store Privacy URL points to Google's account policy; scope_extension=false, data_collection=true, third_party_sharing=true → +10.0 privacy.
• uninstall_url_hijack manifest chrome.runtime.setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_campaign=bg&utm_content=uninstall
• install_url_hijack manifest onInstalled opens https://gameograf.com/?utm_source=install&utm_campaign=bg&utm_content=install
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; combined with 'search' permission — monetization surface.
• dom_xss_sink_no_csp crx innerHTML sinks in popup.js and calendar.js; csp_present=false raises XSS risk per v3 FIX B.
• no_developer_name store developer_name is empty string despite verified_publisher=true; accountability gap.
• google_generic_privacy_policy store Privacy policy URL is myaccount.google.com/privacypolicy — applies to Google, not this extension.
• newtab_monetization_pattern store Pokemon fan-art theme + newtab override + install/uninstall tracking URLs = monetization shell pattern (+2.0 webstore).
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — May And Kyogre Pokemon Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.19 -> 7.69 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search queries; medium risk for a NewTab/wallpaper extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; low risk on its own.
• chrome_url_overrides.newtab medium Replaces new-tab page; core monetization surface for this category.
