Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Download Manager Integration Checklist [click-fraud] (+2.0, capped).
• Google brand impersonation: dev 'Merin' is unverified but uses Google's privacy policy and mentions Google brand.
• Privacy policy is Google's generic account policy — not scoped to this extension; data_collection+third_party_sharing admitted.
• content_scripts on <all_urls> injects JS into every site despite only 'storage' in permissions[].
• Description promises download integration but lacks 'downloads' permission — mismatch raises shell-pattern concern.

Evidence

• brand_impersonation store brand_mention: Google mentioned, confirmed_owner=false, is_impersonation=true; dev is 'Merin' with no domain.
• generic_google_privacy_policy store Privacy URL is myaccount.google.com/privacypolicy; scope_extension=false, data_collection=true, third_party_sharing=true.
• content_scripts_all_urls manifest content_scripts_matches=[<all_urls>] injects into every page; no corresponding host_permissions declared.
• description_permission_mismatch store Promises download functionality but 'downloads' permission absent; description_promise mismatch flagged.
• dom_xss_sink crx innerHTML assigned from variable in popup.100f6462.js; no CSP to mitigate; DOM-XSS risk.
• external_js_host crx js_external_hosts includes reactjs.org; extension references external domain in code.
• stale_update store months_since_update=18; at the 12-24 month band boundary (+6.0 maintenance).
• no_developer_email store developer_email is empty; no contact accountability; unverified publisher.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Download Manager Integration Checklist [click-fraud]; score 4.93 -> 6.93 (+2.0 cap 2.5).

Permissions Breakdown

• storage low Stores local data only; minimal risk in isolation.
• content_scripts <all_urls> high Injects JS into every page; broad reach even without explicit host_permissions.
