Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Bmw m2 under the rain [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL hijack both redirect to gameograf.com with tracking UTM params — classic monetization shell.
• NewTab override with search permission = ad-monetization funnel replacing every new tab.
• No CSP on MV3 extension with innerHTML DOM-XSS sinks in popup.js and calendar.js.
• Unverified publisher, tiny install base (14), and automotive-theme shell with no stated utility beyond wallpaper.

Evidence

• install_url_hijack + uninstall_url_hijack manifest Both onInstalled and uninstall open https://gameograf.com/?utm_source=dekuy — monetization shell pattern confirmed.
• newtab_override manifest chrome_url_overrides.newtab set to newtab.html; combined with 'search' permission = search monetization.
• dom_sink_innerhtml_userctrl (x2) crx innerHTML sinks in popup.js and calendar.js with no CSP — DOM-XSS risk if any data source is attacker-controlled.
• no_csp manifest content_security_policy is null; MV3 provides strict default but innerHTML sinks remain exploitable.
• developer_identity_mismatch store developer_name=Dekuy.com, email=support@gameograf.com, privacy URL on api.gameograf.com — two distinct brand identities.
• very_low_installs store Only 14 installs with automotive wallpaper theme; utility is cosmetic, permissions exceed stated function.
• privacy_policy_scope api Policy fetched, scoped, discloses data collection, retention, and third-party sharing — adequate but hosted on API subdomain.
• operator_cluster_singleton api sibling_count=0; no known cluster, but gameograf.com fingerprint with UTM tracking suggests template-based shell.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Bmw m2 under the rain [adware] + malext.io malicious_extension_sentry; score 4.52 -> 7.02 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search provider; paired with newtab override = search monetization surface.
• host_permissions: https://api.gameograf.com/* medium Scoped to developer domain only; used for policy/content fetch.
• chrome_url_overrides.newtab medium Replaces new tab page — primary monetization vector for this category.
