Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Wind Breaker Wallpapers – Anime Wallpapers [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override + 'search' permission enables monetization/search-redirect on every new tab.
• Uninstall and install URL hijack both active — classic monetization shell fingerprint.
• bit.ly affiliate/cloaking redirector in js_external_hosts.
• mlionltd.github.io external JS host is unverified/throwaway-tier.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set — every new tab is controlled by this extension.
• uninstall_url_hijack manifest setUninstallURL to gameograf.com with UTM params — monetization shell signal.
• install_url_hijack manifest onInstalled opens gameograf.com with UTM params — install hijack confirmed.
• affiliate_hit crx bit.ly in js_external_hosts — affiliate/cloaking redirector (threat_intel.affiliate_hits).
• external_unverified_host crx mlionltd.github.io in js_external_hosts — uncontrolled third-party JS origin.
• dom_xss_sink crx innerHTML set from variable in js/popup.js — DOM-XSS risk, no CSP present.
• stale_update store Last updated May 2025 but months_since_update=16 indicates prior gap; 6-12mo band applies.
• no_csp manifest content_security_policy is null — MV3 default helps but no explicit hardening.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Wind Breaker Wallpapers – Anime Wallpapers [adware] + malext.io malicious_extension_sentry; score 4.43 -> 6.93 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search queries; concerning for a wallpaper/NewTab extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces every new tab — prime monetization/surveillance surface.
