Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Taylor Swift Wallpapers [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces new-tab page, enabling search/ad monetization on every new tab opened.
• Uninstall and install URL hijack redirect to gameograf.com — monetization shell fingerprint.
• bit.ly affiliate/cloaking link in js_external_hosts — affiliate injection risk.
• mlionltd.github.io external JS host is unverifiable third-party; potential supply-chain risk.

Evidence

• chrome_url_overrides.newtab medium Replaces new-tab page — primary monetization surface for wallpaper/search shells.
