Study Reveals Browser Wallets Enable Cross‑Site Tracking
🔎 Researchers at KU Leuven analyzed 85 popular browser-based crypto wallet extensions and found systemic privacy leaks that can link and de-anonymize users. The wallets reveal addresses in clear text to external servers, announce installed wallets to sites, and often fail to revoke access on logout. These behaviors allow separate addresses to be correlated, stale permissions to persist across sessions, and authorized wallets to expose addresses inside embedded frames, enabling cross-site tracking and potential deanonymization.
