Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Ice Spice Wallpapers [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic account policy — does not scope to this extension; data collection and 3rd-party sharing admitted.
• Uninstall AND install URL hijack to gameograf.com UTM tracking — monetization shell pattern.
• NewTab override with 'search' permission — classic search-monetization surface.
• Verified publisher discount capped to -1.0: stale 16 months and generic policy.

Evidence

• uninstall_url_hijack + install_url_hijack manifest Both onInstall and onUninstall redirect to gameograf.com UTM URLs — textbook monetization shell (+3.0+2.0 Webstore).
• chrome_url_overrides.newtab manifest NewTab replaced with index.html; paired with 'search' permission for search-intercept monetization.
• privacy_policy_generic store Policy URL is myaccount.google.com/privacypolicy — Google's own policy, not scoped to extension; data_collection+3rd_party_sharing=true.
• dom_sink_innerhtml_userctrl crx popup.js assigns innerHTML from variable without sanitization; no CSP present amplifies risk.
• no_csp manifest content_security_policy is null (MV3 default applies but no explicit CSP tightens XSS surface).
• developer_name_missing store developer_name is empty string; reduces accountability (+1.0 Reputation).
• verified_publisher_cap store Verified publisher discount capped at -1.0 per 0c: months_since_update=16 (>18 threshold near; generic policy is non-resolving).
• js_external_host_mlionltd_github_io crx External JS host mlionltd.github.io — third-party GitHub Pages host, not dev-controlled domain.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Ice Spice Wallpapers [adware] + malext.io malicious_extension_sentry; score 5.17 -> 7.67 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying search provider; pairs with newtab override to intercept search.
• chrome_url_overrides.newtab medium Replaces new-tab page; core monetization surface for wallpaper/search shells.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
