Top Risks

• Uninstall URL hijack to owhit.com — classic monetization/tracking shell pattern (Webstore +3.0).
• Install URL hijack to owhit.com — opens 3rd-party page on install (Webstore +2.0).
• Privacy policy is Google's generic account policy — does not scope this extension; admits data collection and 3rd-party sharing (Privacy +10.0).
• NewTab override + search permission enables search-monetization even without explicit redirect detected.
• 6 siblings share the same uninstall URL domain (owhit.com), indicating a wallpaper-shell farm operator.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → https://owhit.com/uninstall; 6 siblings share same uninstall domain.
• install_url_hijack crx onInstalled opens https://owhit.com/grinch-live-wallpaper/ — 3rd-party redirect on install.
• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new tab page.
• generic_privacy_policy store PP is Google's own account policy (456 KB); scope_extension=false, data_collection=true, third_party_sharing=true.
• developer_identity store developer_name equals email (info@walltab.com); no verified publisher badge; no featured badge.
• js_external_hosts crx References chat.openai.com, instagram.com, netflix.com, youtube.com, x.com, owhit.com — 8 distinct hosts.
• operator_cluster_uninstall api sibling_counts_by_dim.uninstall_url=6 confirms owhit.com wallpaper-shell farm across multiple extensions.
• cve_findings crx jquery 3.7.1 bundled — no CVEs found; cve_findings_raw empty.

Permissions Breakdown

• search medium Allows reading/modifying search queries; paired with newtab override enables search hijacking.
• chrome_url_overrides.newtab medium Replaces every new tab; prime real estate for ad injection and search monetization.
