Study of 85 Crypto Wallet Extensions Finds Address Leaks and Cross-Site Tracking Risks
Researchers at KU Leuven analyzed 85 popular cryptocurrency wallet browser extensions and identified privacy vulnerabilities that allow address linking and cross-site tracking. The wallet communication patterns with websites and blockchain servers expose user activity in ways that enable deanonymization and user tracking across sites.
Why it matters: Cryptocurrency users relying on browser-based wallet extensions face privacy leakage that undermines the anonymity properties they expect, making them targets for tracking by advertisers, malicious sites, or adversaries attempting to correlate their on-chain activity.
