Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Jojo Dio Brando Gameograf [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall URL hijack and install URL hijack — classic ad-monetization shell pattern.
• No developer name listed; obfuscated manifest strings (__MSG_appName__) reduce transparency.
• Stale 15 months (6-12mo band) with new-tab override raises supply-chain concern.
• innerHTML DOM-XSS sink in popup.js with no CSP; if input ever reaches it, XSS is possible.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; search override + install/uninstall URL hijack pattern.
• uninstall_url_hijack crx setUninstallURL to https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg
• no_csp manifest content_security_policy is null; MV3 default applies but dom_sink_innerhtml_userctrl present.
• dom_sink_innerhtml crx js/popup.js: popupContainer.innerHTML = html — potential DOM-XSS if html is user-controlled.
• verified_publisher_stale store Verified publisher but 15 months since update; discount capped at -1.0 per invariant 0c.
• no_developer_name store developer_name is empty string; manifest name uses __MSG_appName__ placeholder.
• privacy_policy_adequate api Policy fetched, scoped to extension, data_collection=true, retention=true, third_party_sharing=true.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Jojo Dio Brando Gameograf [adware] + malext.io malicious_extension_sentry; score 4.19 -> 6.69 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading search queries; paired with newtab override this enables search monetization.
• host_permissions: https://api.gameograf.com/* low Scoped to own API domain only; not broad host access.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary vector for search/ad monetization in this category.
