A potential security risk inherent in all standard browsers has been described by two Princeton university computer scientists. The researchers reportedly claim that unscrupulous Web site operators can follow a trail of cookies to discern which other sites a user has recently visited. A report by United Press International said computer science professor Edward Felten and graduate student Michael Schneider described the technique at the Association for Computing Machinery Conference on Computer and Communications Security in Athens, Greece. The duo call the phenomenon a "timing attack," and claim that when a surfer goes to a particular site, that site could run a program asking the browser questions about other sites. A quick response indicates a recent visit.
