New SSD timing method lets sites track users without cookies
AFBytes Brief
A new technique called FROST uses SSD activity and browser storage to track users across sites. The method bypasses traditional cookie and cache defenses.
Why this matters
Covert tracking via hardware behavior can undermine user privacy controls and expose browsing habits to advertisers or data brokers.
Quick take
- Money Angle
- Data brokers and ad networks may gain new high-resolution signals that increase the value of user profiles.
- Market Impact
- Privacy-focused browsers and hardware vendors could see renewed interest if the technique spreads.
- Who Benefits
- Advertising technology firms obtain finer-grained behavioral data that improves targeting accuracy.
- Who Loses
- Users lose an additional layer of anonymity when visiting sites that deploy the FROST method.
- What to Watch Next
- Watch for browser vendor patches or new W3C standards addressing storage-timing side channels.
