Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — VnChatGPT [browser-hijack] + malext.io malicious_extension_sentry (+2.5, capped).
• Search provider override sets vnchatgpt.com as default engine, routing all user queries through an unverified operator.
• Privacy policy is Google's generic account policy — not scoped to this extension; admits data collection and third-party sharing.
• No developer identity (name, email, domain) — zero accountability; anonymous publisher.
• No update date or install count available — extension provenance entirely unverifiable.

Evidence

• search_provider_override manifest chrome_settings_overrides sets VnChatGPT as default search engine; all queries routed to vnchatgpt.com.
• generic_google_privacy_policy store Privacy policy URL is Google account policy (myaccount.google.com); scope_extension=false, data_collection=true, third_party_sharing=true.
• no_developer_identity store developer_name and developer_email both empty; no verified publisher; no 'Offered by' info.
• missing_store_metadata store installs, rating, last_updated all null — cannot assess reach or maintenance.
• content_script_narrow manifest content_scripts limited to https://*.vnchatgpt.com/* — operator's own domain only.
• no_cve_findings crx cve_findings_raw empty; no CVE exposure detected.
• no_bad_hosts crx threat_intel.bad_host_hits and monetization_hits empty; js_external_hosts empty.
• obfuscation_clean crx obfuscation_score=0.0; code_findings_raw empty; 1 JS file scanned with no findings.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — VnChatGPT [browser-hijack] + malext.io malicious_extension_sentry; score 4.44 -> 6.94 (+2.5 cap 2.5).

Permissions Breakdown

• chrome_settings_overrides.search_provider (is_default=true) medium Overrides default search engine to vnchatgpt.com; high-impact UX change, routes all searches through operator.
• content_scripts on https://*.vnchatgpt.com/* low Narrow host scope limited to operator's own domain; low lateral reach.
