Top Risks

• NewTab override with install/uninstall URL hijack — classic traffic-monetization shell pattern with 7 compound siblings
• Privacy policy URL returns connection error (fetch_error) — treated as no policy, score +10.0
• Operator cluster: 28 siblings by dev email, 7 by compound fingerprint — large-scale wallpaper farm
• Two innerHTML DOM-XSS sinks with no CSP — elevated code quality risk in MV3 context
• No developer display name; manifest uses __MSG__ placeholders obscuring actual title/description

Evidence

• uninstall_url_hijack + install_url_hijack crx Both onInstall and onUninstall redirect to gameograf.com with UTM tracking — monetization shell.
• chrome_url_overrides.newtab manifest Replaces new tab page (newtab.html); paired with search permission = search-monetization risk.
• operator_cluster api 7 compound siblings, 28 siblings by dev email — large NewTab/wallpaper farm under gameograf.com.
• privacy_policy_fetch_error api Privacy policy URL unreachable (ConnectionError); classified as fetched==false → +10.0 privacy.
• dom_sink_innerhtml_userctrl (x2) crx innerHTML sinks in popup.js and calendar.js with no CSP — DOM-XSS risk per FIX B.
• new_tab_override_monetization store NewTab + install/uninstall hijack + search permission = +2.0+3.0+3.0 webstore signals.
• no_developer_name store Developer display name is empty; manifest name is __MSG_appName__ — identity opacity.
• verified_publisher store Verified publisher badge present; -3.0 reputation credit applied (floor 2.0 respected).

Permissions Breakdown

• search medium Allows reading/manipulating search queries; relevant for NewTab/search-override pattern.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; expected for a NewTab extension fetching content.
• chrome_url_overrides.newtab medium Replaces new tab page — high-reach monetization surface, counted per v2 rule (a).
