Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Luffy meditation in beach [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall AND install URL hijacking to gameograf.com UTM-tagged page — classic monetization shell pattern.
• NewTab override with search permission: high-value monetization surface on every new tab.
• innerHTML DOM-XSS sinks in popup.js and calendar.js with no CSP to mitigate.
• No CSP on MV3 extension; MV2 +2.0 penalty not applied but innerHTML risk elevated by csp_present==false.

Evidence

• install_url_hijack + uninstall_url_hijack manifest Both install and uninstall redirect to https://gameograf.com/?utm_source=dekuy — monetization shell indicator.
• newtab_override manifest chrome_url_overrides.newtab set to newtab.html; extension controls every new tab opened.
• dom_sink_innerhtml_userctrl x2 crx innerHTML sinks in popup.js and calendar.js; no CSP present to block XSS escalation.
• no_csp manifest content_security_policy is null; csp_present==false increases innerHTML risk to +2.0 under FIX B.
• privacy_policy_scope api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true — adequate.
• webstore_install_monetization store +2.0 install URL hijack + +3.0 uninstall URL hijack applied under webstore monetization rules.
• developer_identity store developer_name=Dekuy.com but email/domain=gameograf.com; not verified publisher, not featured.
• maintenance_3_to_6mo store months_since_update=4; +1.5 maintenance score applied.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Luffy meditation in beach [adware] + malext.io malicious_extension_sentry; score 2.93 -> 5.43 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows manipulation of search provider; medium risk for a NewTab/search-override extension.
• host_permissions: https://api.gameograf.com/* medium Scoped to developer API endpoint; enables data exfil to own backend.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary monetization surface for this extension type.
