Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — KATSEYE Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall URL hijack to owhit.com — classic monetization shell pattern tracking departing users.
• Install URL hijack to owhit.com — opens 3rd-party page on install, typical ad-redirect behavior.
• Privacy policy is Google's generic account policy — not scoped to this extension, admits data collection and 3rd-party sharing.
• Developer is a free-webmail Gmail address with no developer name or verified business identity.

• verified_publisher store verified_publisher=true; applied -2.0 reputation discount but floor raised by free-webmail + numbered alias.
