Top Risks

• NewTab override replaces browser new-tab page — primary monetization/search-hijack surface.
• Uninstall and install URL hijacks both fire to gameograf.com tracking URLs.
• No CSP declared (MV3 default applies but csp_present=false); innerHTML sink in popup.js creates DOM-XSS risk.
• Developer name empty; verified publisher status is present but extension is 15 months stale.
• Search permission combined with newtab override raises search-provider concern despite single engine seen.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces new-tab page.
• uninstall_url_hijack crx setUninstallURL targets 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_sink crx innerHTML assigned from variable in js/popup.js; no CSP to mitigate.
• verified_publisher store Developer has verified publisher badge; domain gameograf.com resolves and is not throwaway.
• stale_extension store 15 months since last update (June 2025); maintenance pillar elevated to 6.0.
• privacy_policy_adequate api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true — full disclosure.
• low_installs store Only 210 installs; no ratings; operator_cluster sibling_count=0.

Permissions Breakdown

• search medium Grants ability to interact with browser search; medium risk for a NewTab override context.
• host_permissions: https://api.gameograf.com/* low Scoped to dev-controlled API domain only; narrow host access.
• chrome_url_overrides.newtab medium Replaces new-tab page; monetization/search-hijack surface per v2 calibration rule (a).
