Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Minecraft Sakura Pond Live Wallpaper [adware] (+2.0, capped).
• NewTab override + search permission: classic ad-monetization shell pattern replacing every new tab for 1,000 users.
• Uninstall URL hijack and install URL hijack both present — post-install and post-remove tracking.
• Brand impersonation: 'Minecraft' used without confirmed ownership; Mojang/Microsoft trademark issue.
• Privacy policy discloses data collection and third-party sharing but lacks retention details.

Evidence

• newtab_override manifest chrome_url_overrides.newtab=newtab.html replaces every new tab; monetization shell pattern.
• uninstall_url_hijack crx uninstall_url_hijack=true; extension sets uninstall callback URL to track removal.
• install_url_hijack crx install_url_hijack=true; extension opens URL on install, typical affiliate/ad-tech signal.
• brand_impersonation store brand_mention.is_impersonation=true for 'minecraft'; developer domain tabplugins.com not confirmed owner.
• external_js_hosts crx JS contacts 7 external hosts incl. chatgpt.com, instagram.com, x.com, youtube.com — broad reach for a wallpaper.
• no_developer_name store developer_name is empty; no accountable publisher identity listed on store page.
• privacy_policy_retention_missing api Policy collects data and shares with third parties but retention period not disclosed.
• csp_absent_mv3 manifest content_security_policy=null on MV3; no explicit CSP hardening despite external JS hosts.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Minecraft Sakura Pond Live Wallpaper [adware]; score 5.14 -> 7.14 (+2.0 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search provider; medium risk for query interception.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary surface for ad-monetization shells.
