Top Risks

• NewTab override hijacks every new tab; combined with uninstall/install URL hijacks indicates monetization shell pattern.
• Both install and uninstall URL hijack to gameograf.com UTM-tracked landing page.
• Two innerHTML-from-variable DOM-XSS sinks with no CSP amplifies exploit risk.
• No developer name listed despite verified publisher status reduces accountability signal.
• Low install count (18) with NewTab + search override is tail-attack-surface shape.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab.
• uninstall_url_hijack crx setUninstallURL points to https://gameograf.com/?utm_source=extension&utm_medium=install
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install
• dom_xss_sinks crx innerHTML assigned from variable in js/popup.js and js/calendar.js; no CSP present.
• no_csp manifest content_security_policy is null; MV3 strict default applies but innerHTML sinks still risky.
• verified_publisher store Developer verified; domain gameograf.com resolves and is not throwaway.
• privacy_policy api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• low_installs store Only 18 installs; NewTab + search override at this scale is a tail-attack-surface pattern.

Permissions Breakdown

• search medium Allows querying search providers; relevant to NewTab monetization potential.
• host_permissions:https://api.gameograf.com/* low Scoped to developer's own API domain only.
• chrome_url_overrides:newtab medium Replaces new tab page; primary monetization vector for this category.
