Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Purple Porsche in Tokyo Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy URL is on a different domain (haberikra.com) and timed out — effectively no accessible policy.
• NewTab override replaces every new tab; combined with 'search' permission enables search monetization.
• Uninstall and install URL hijacks both redirect to gameograf.com with UTM tracking parameters.
• innerHTML DOM-XSS sink in popup.js with no CSP — risk of DOM-based XSS if data is attacker-influenced.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — controls every new tab page.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• privacy_policy_fetch_failed api Policy URL haberikra.com/privacy-policy/ timed out; fetched=false — treated as no accessible policy.
• dom_xss_sink crx dom_sink_innerhtml_userctrl in js/popup.js; no CSP present — DOM-XSS risk.
• no_csp manifest content_security_policy is null; MV3 default CSP applies but no explicit extension policy.
• no_developer_name store developer_name is empty string in store listing.
• stale_extension store Last updated June 2025; months_since_update=14 — falls in 12-24mo band (+6.0 maintenance).
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Purple Porsche in Tokyo Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.18 -> 7.68 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search queries; paired with newtab override raises monetization risk.
• host_permissions: https://api.gameograf.com/* low Scoped to dev-controlled API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces every new-tab page; primary monetization vector for this category.
