Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Saja Boys Jinu Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with install/uninstall URL hijack — monetization shell pattern scoring +4.0 on webstore pillar.
• Privacy policy is Google's own account policy (not scoped to this extension), admits data collection and 3rd-party sharing — scores 10.0.
• No developer name listed; verified publisher badge doesn't compensate for unscoped generic privacy policy.
• DOM-XSS sinks (innerHTML from variable) in popup.js and calendar.js with no CSP present — elevated XSS risk.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — captures all new-tab events.
• uninstall_url_hijack crx setUninstallURL to https://gameograf.com/?utm_source=gameograf — 3rd-party redirect on uninstall.
• install_url_hijack crx onInstalled opens https://gameograf.com/stranger-things-5-live-wallpaper/ — 3rd-party redirect on install.
• generic_privacy_policy api Privacy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink_no_csp crx innerHTML from variable in popup.js and calendar.js; csp_present=false amplifies risk.
• no_developer_name store developer_name is empty string; identity accountability reduced.
• verified_publisher store verified_publisher=true for gameograf.com domain; domain resolves and is not throwaway.
• maintenance_6_to_12mo store months_since_update=7; falls in 6-12 month band (+3.5).
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Saja Boys Jinu Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.19 -> 7.69 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows search provider interaction; combined with newtab override raises search-hijack risk.
• host_permissions: https://api.gameograf.com/* medium Scoped to dev's own API domain; enables outbound data transfer to developer.
• chrome_url_overrides.newtab medium Replaces new tab page — primary monetization surface, captures all new-tab events.
