Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Arona anime [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL hijack both redirect to gameograf.com with UTM tracking — clear monetization shell pattern.
• NewTab override replaces every new tab; combined with search permission creates search/traffic monetization surface.
• Two innerHTML DOM-XSS sinks with no CSP; no content_security_policy declared (MV3 default applies but no explicit hardening).
• Developer name (Dekuy.com) mismatches email domain (gameograf.com) — unclear operator identity.

Evidence

• install_url_hijack manifest onInstalled opens https://gameograf.com/?utm_source=dekuy&utm_medium=dekuy — affiliate/monetization redirect.
• uninstall_url_hijack manifest setUninstallURL targets https://gameograf.com/?utm_source=dekuy&utm_medium=dekuy — traffic harvesting on removal.
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new tab for 24 users.
• dom_xss_sink crx Two innerHTML assignments from variables in popup.js and calendar.js with no CSP declared.
• developer_identity_mismatch store Developer name Dekuy.com but email support@gameograf.com and API host api.gameograf.com — split identity.
• monetization_shell_pattern store Anime-theme NewTab with dual UTM-tracked URL hijacks and search override matches low-effort traffic-monetization cluster.
• privacy_policy_scoped api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true — adequate.
• low_install_monetization store Only 24 installs with newtab+search+dual URL hijack signals tail-attack-surface monetization shell.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Arona anime [adware] + malext.io malicious_extension_sentry; score 4.09 -> 6.59 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows search-provider interaction; paired with newtab override elevates search hijack risk.
• host_permissions: https://api.gameograf.com/* low Scoped to dev's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new tab page; common monetization vector with install/uninstall URL hijack present.
