open wireless network (e.g. Wireless@SG) and try to use secure encrypted channel whenever possible (e.g. Wireless@SGx) cos your login sessions to sites that used cookies and not on https:// (e.g. Facebook) can be hijacked with ease. saw this discussion on-going on /. , and the tool is freely available! just grab Firesheep, a Firefox extension, and anyone is good to go. impressive huh?
oh btw, the suggestion to use “Free” as password for encrypted but FREE networks is a good idea i though (:
