Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Stitch Cosmic Adventure Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL both hijacked to gameograf.com — confirmed monetization shell pattern.
• NewTab override with search permission enables persistent search/ad revenue capture on every new tab.
• Privacy policy URL unreachable (fetch_error); treated as no policy — full +10 privacy score.
• Free-webmail developer (gmail), no developer name, no verified business domain — low accountability.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → gameograf.com with ovkas UTM params; classic monetization redirect.
• install_url_hijack crx onInstalled opens gameograf.com with ovkas UTM params; confirms traffic-monetization intent.
• newtab_override manifest chrome_url_overrides.newtab set to index.html; every new tab controlled by extension.
• privacy_policy_unreachable api fetch_error:ConnectionError on https://ovkas.com/privacy-policy; policy treated as absent.
• free_webmail_no_devname store Developer email halilseker3455@gmail.com; developer_name empty; no verified business domain.
• js_external_hosts_broad crx Extension JS contacts gameograf.com, games.ovkas.com, instagram.com, netflix.com, youtube.com, x.com.
• verified_publisher_low_value store verified_publisher=true but dev is free-webmail with no name; verification provides limited assurance.
• newtab_monetization_shape crx NewTab + search permission + install/uninstall hijack to ad-UTM URL = textbook traffic-monetization cluster.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Stitch Cosmic Adventure Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 6.14 -> 8.64 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying browser search; combined with newtab override, enables search monetization.
• chrome_url_overrides.newtab high Replaces every new tab with extension page; prime surface for ad injection and search hijacking.
