Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Minecraft tranquil morning pond [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall AND install URL hijack both redirect to gameograf.com ad-tracking UTM URLs — monetization shell pattern.
• NewTab override with Minecraft brand impersonation (confirmed_owner=false) — fan-content/trademark violation.
• No CSP on MV3 extension with innerHTML DOM-XSS sinks in popup.js and calendar.js.
• Unverified developer: mismatch between developer_name (Dekuy.com) and email domain (gameograf.com) with no verified publisher badge.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → https://gameograf.com/?utm_source=dekuy&utm_medium=dekuy (3rd-party UTM redirect).
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=dekuy&utm_medium=dekuy on install.
• brand_impersonation store Title references 'Minecraft'; developer gameograf.com is not a confirmed owner of the Minecraft brand.
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; every new tab replaced, combined with search permission.
• no_csp manifest content_security_policy is null; two innerHTML DOM-XSS sinks present in popup.js and calendar.js.
• developer_mismatch store developer_name=Dekuy.com but email=support@gameograf.com; not a verified publisher.
• privacy_policy_third_party_sharing api Policy fetched, scoped, admits data collection + retention + third-party sharing.
• dom_sink_innerhtml crx dom_sink_innerhtml_userctrl in popup.js and calendar.js; no CSP mitigates XSS risk.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Minecraft tranquil morning pond [adware] + malext.io malicious_extension_sentry; score 4.73 -> 7.23 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; medium risk on its own but paired with newtab override.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited reach.
• chrome_url_overrides.newtab medium Replaces every new-tab page; monetization/tracking surface. Scored under v2 rule (a).
