發現懷疑假免費無線網絡 / Fake wireless network found in Hong Kong

近日香港發現疑似假免費無線網絡, 名稱為 “Free Public Wifi”. 該無線網絡為開放網絡並不設加密連接. 根據電訊網絡商 PCCW 指出, 該網絡並非真正 Wifi 熱點, 而是偽無線網絡 (viral SSID).

其實使用無線上網時除了注意連接正確及信任網絡外, 仍需注意如果錯誤地連接其他非信任網絡有機會被人入侵 / 資料被偷.

經明查暗訪後, 其實這是微軟 WinXP SP3 以下版本內既一個 bug, 這個 bug 令 “Free Public Wifi” 不只在香港出現, 還遍佈世界各地, 像電腦病毒般漫延.

Recently, there is an free wi-fi network name “Free Public Wifi” available in most famous shopping malls of Hong Kong. However, there is no network traffic when you try to stuff the net. According to an ISP, PCCW, this is a fake wifi network (viral SSID). This SSID not only exist in Hong Kong, but all over the world. This mainly because a bug exist in WinXP SP2 or lower version. That bug will let the old version windows remember this SSID and recall it when no wifi available around.

The only workaround is avoid to join this wireless network, because the we can’t fix the problem in other computers not owned by us, right?
