Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Minecraft sunset [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Minecraft brand impersonation by unverified developer (gameograf.com / Dekuy.com mismatch).
• Uninstall and install URL hijacks both redirect to gameograf.com UTM-tracked affiliate URL.
• NewTab override + search permission = classic traffic-monetization shell pattern.
• innerHTML DOM-XSS sinks with no CSP; remote content from api.gameograf.com could be injected.

Evidence

• brand_impersonation store brand_mention.is_impersonation=true for 'minecraft'; developer not a confirmed owner of the brand.
• uninstall_url_hijack crx uninstall_url_target=https://gameograf.com/?utm_source=dekuy&utm_medium=dekuy — 3rd-party UTM redirect.
• install_url_hijack crx install_url_target=https://gameograf.com/?utm_source=dekuy&utm_medium=dekuy — opens on install.
• newtab_override manifest chrome_url_overrides.newtab=newtab.html combined with search permission; monetization shell pattern.
• dom_xss_sink crx innerHTML assigned from variable in popup.js and calendar.js; no CSP to mitigate XSS.
• no_csp manifest content_security_policy is null; MV3 default CSP applies but no explicit restriction on connect-src.
• developer_mismatch store developer_name=Dekuy.com, developer_email=support@gameograf.com — two distinct brand identities.
• low_install_newtab store Only 26 installs for a NewTab extension with Minecraft branding and UTM monetization hooks.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Minecraft sunset [adware] + malext.io malicious_extension_sentry; score 4.41 -> 6.91 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search provider; combined with newtab override is a monetization pattern.
• host_permissions: https://api.gameograf.com/* medium Scoped host access to developer API; enables data exfil to dev-controlled endpoint.
• chrome_url_overrides.newtab medium NewTab override redirects every new tab; primary monetization/tracking surface.
