Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Before the road 8bit [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL hijack to gameograf.com affiliate URL — classic monetization shell pattern.
• Privacy policy URL returns connection error; effective no-policy state for a NewTab extension.
• NewTab override captures every new-tab open event for all users indefinitely.
• Two unguarded innerHTML DOM-XSS sinks with no CSP to limit exploitation.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → https://gameograf.com/?utm_source=dekuy&utm_medium=dekuy (3rd-party affiliate UTM).
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=dekuy&utm_medium=dekuy (3rd-party affiliate UTM).
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; captures every new-tab for monetization.
• privacy_policy_fetch_error api privacy_policy_classification.fetched=false; ConnectionError — policy unreachable, treated as absent.
• dom_xss_sinks crx Two innerHTML user-controlled sinks in popup.js and calendar.js with csp_present=false.
• developer_mismatch store developer_name=Dekuy.com but email domain=gameograf.com; uninstall/install URLs point to gameograf.com.
• no_csp manifest content_security_policy is null (MV3, so no extra penalty, but amplifies XSS sink risk).
• search_permission_newtab manifest 'search' permission + newtab override = search monetization pattern even without settings_overrides.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Before the road 8bit [adware] + malext.io malicious_extension_sentry; score 5.34 -> 7.84 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Grants ability to manipulate search provider; medium risk for a NewTab override extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary monetization surface, captures all new-tab events.
