Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Resident Evil Rain of Death Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab — persistent reach into daily browsing.
• Uninstall and install URL hijacks redirect to gameograf.com with UTM tracking.
• No CSP declared (csp_present=false); innerHTML sinks in popup.js and calendar.js elevate DOM-XSS risk.
• Developer name is empty; verified publisher without displayed name reduces accountability.
