Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Black Cat Cowboy In Desert Sunset Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy URL returns fetch error — effectively no accessible policy; pillar maxes out.
• NewTab override with uninstall+install URL hijack to gameograf.com — monetization shell pattern.
• Two innerHTML DOM-XSS sinks with no CSP — DOM injection risk on every new tab page.
• No developer name listed; 'Offered by' blank increases accountability gap.

Evidence

• dom_xss_sinks crx Two dom_sink_innerhtml_userctrl findings in popup.js and calendar.js; no CSP present.
• no_developer_name store developer_name is empty string — no 'Offered by' accountability.
• verified_publisher_cap store Verified publisher discount capped at -1.0 per v3.5(E): privacy policy unreachable.
• js_external_hosts crx 12 external hosts including chat.openai.com and multiple Google services — broad reach for a wallpaper.

Permissions Breakdown

• search medium Allows reading/modifying search queries; medium risk on its own.
• chrome_url_overrides.newtab high Replaces every new tab — prime real estate for search hijack and ad monetization.
• host_permissions: https://api.gameograf.com/* medium Scoped to own API domain; narrows exfil surface but enables data send-back.
