Public Wifi networks offer a larger security threat than ever to computer users because hackers have the ability to "poison" users' browser caches to present fake Web pages and even steal data later, according to security researcher Mike Kershaw.
Kershaw said the problem stems from open network that have no client protection. "Nothing stops us from spoofing the [wireless access point] and talking directly to the client," he said.
Kershaw suggested that users continuously clear out the cache on a manual basis or use private-browser mode.
