Top Risks

• Minecraft brand impersonation by unverified developer (gameograf.com, no 'Offered by' name).
• NewTab override + search permission: classic ad-monetization/search-hijack shell pattern.
• Privacy policy is Google's generic policy — does not scope to this extension; admits data collection and 3rd-party sharing.
• Uninstall and install URL hijacks redirect to gameograf.com UTM-tracked pages.
• innerHTML sinks in calendar.js and popup.js without CSP — DOM-XSS risk on newtab page.

Evidence

• brand_impersonation store brand_mention.is_impersonation=true for 'minecraft'; developer gameograf.com is not a confirmed Mojang/Microsoft affiliate.
• newtab_override_with_search manifest chrome_url_overrides.newtab set + 'search' permission declared — NewTab monetization pattern.
• privacy_policy_generic store Policy URL is Google's own privacy policy (myaccount.google.com); scope_extension=false, data_collection=true, third_party_sharing=true.
• uninstall_url_hijack crx chrome.runtime.setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• dom_xss_no_csp crx 2 innerHTML-from-variable sinks (calendar.js, popup.js); csp_present=false on MV3 extension.
• no_developer_name store developer_name is empty string; 'Offered by' field absent, reducing accountability.
• maintenance_stale store months_since_update=13 falls in 12-24mo band; +6.0 maintenance score.

Permissions Breakdown

• search medium Allows reading/modifying search provider; combined with newtab override raises monetization risk.
• chrome_url_overrides.newtab high Replaces new-tab page entirely; primary vector for search hijack and ad monetization.
• host_permissions: https://api.gameograf.com/* medium Grants cross-origin XHR to developer's own API; data exfil surface.
