Overview

• The SnailLoad technique allows attackers to spy on online activities without malware or intercepting data.
• It works by analyzing latency variations when users download a small, non-malicious file from an attacker's server.
• Researchers achieved up to 98% accuracy in identifying videos watched by users with slower internet connections.
• The method is difficult to counteract, as it exploits fundamental aspects of internet data transmission.
• Currently, there are no practical solutions to mitigate this vulnerability without significantly slowing down internet speeds.
