Top Risks

• Privacy policy is Google's generic policy — does not scope to this extension; admits data collection and third-party sharing (Privacy +10).
• New-tab override with install/uninstall URL hijack to gameograf.com — monetization shell pattern.
• Uninstall and install URL hijacks both redirect to gameograf.com UTM-tracked URLs.
• No CSP declared (MV3 mitigates somewhat, but two innerHTML sinks present with no policy protection).
• Developer name blank; no 'Offered by' display name increases accountability gap.

Evidence

• privacy_policy_generic store Privacy URL is Google's own account policy (scope_extension=false, data_collection=true, third_party_sharing=true) — Privacy pillar +10.
• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — primary new-tab replacement with monetization shape.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=gameograf — 3rd-party UTM tracking on uninstall.
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install — 3rd-party UTM on install.
• dom_sink_innerhtml_userctrl crx Two innerHTML-from-variable sinks in popup.js and calendar.js; no CSP to mitigate DOM-XSS.
• no_developer_name store developer_name is blank — no 'Offered by' accountability signal; Reputation +1.0.
• verified_publisher store Verified publisher badge present; Reputation -3.0 discount applied (floor 2.0 not breached by monetization here).
• cve_findings_empty crx No CVEs detected in bundled libs (jquery 3.7.1 is current/safe); CVE pillar = 0.

Permissions Breakdown

• search medium Allows overriding search provider; medium risk for a NewTab/wallpaper extension.
• host_permissions: https://api.gameograf.com/* low Scoped to own API domain only; reasonable for wallpaper content fetch.
• chrome_url_overrides.newtab medium Replaces new-tab page — primary monetization surface; scored per v2 calibration (a).
