Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Yandere Anime School Girl Samurai Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall AND install URL both hijack to gameograf.com with UTM tracking — confirmed monetization shell.
• New-tab override replaces browser homepage for ad/search revenue; search permission stacks on this.

• Free-webmail dev (gmail) with no verified business domain; no verified-publisher badge.

• external_hosts_broad crx JS references: gameograf.com, google.com, instagram.com, netflix.com, youtube.com, x.com — 6 hosts for a wallpaper.
• new_tab_monetization_shape manifest search permission + newtab override + install/uninstall hijack to same ad domain = classic traffic monetization cluster.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP declared.
