Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Crazy Freekick [credential-theft] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall URL hijack flag set — extension registers an uninstall callback to a 3rd-party URL
• Install URL hijack opens popup/index.html on install — potential onboarding abuse
• Three medium CVEs in bundled jquery@3.2.1 (XSS); version below fixed_in 3.5.0
• Privacy policy hosted on cdn.cloudapi.stream, scope_extension=false; mentions 3rd-party sharing without scoping to this extension

Evidence

• uninstall_url_hijack crx uninstall_url_hijack=true; target null but flag set — extension hooks chrome.runtime.setUninstallURL to 3rd party.
• install_url_hijack crx install_url_hijack=true; target popup/index.html — onInstalled fires navigation.
• jquery_cve_trio crx jquery@3.2.1 bundled with CVE-2019-11358, CVE-2020-11022, CVE-2020-11023 (all medium, fixed in 3.5.0).
• privacy_policy_generic store Policy at cdn.cloudapi.stream: scope_extension=false, data_collection=false, third_party_sharing=true — generic, not extension-scoped.
• free_webmail_no_devname store Developer email nadejdinv@gmail.com; developer_name empty; no business website — minimal accountability.
• sandbox_csp_unsafe manifest Sandbox CSP includes unsafe-inline and unsafe-eval on script-src — elevated XSS risk in sandbox context.
• 10_external_js_hosts crx 10 external JS hosts referenced (createjs.com, goo.gl, cloudapi.stream, etc.); broad external dependency surface.
• low_install_count store Only 56 installs; no verified publisher; no featured badge — negligible trust signals.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Crazy Freekick [credential-theft] + malext.io malicious_extension_sentry; score 4.50 -> 7.00 (+2.5 cap 2.5).
