iOS Safari Security

Hi guys

is it possible that by visiting a site, that the site could have been malicious and somehow exploited safari to get your appleid and email passwords from the ipad, im using an ipad 3 with ios 5.1.1 and recently visited this site Apple Using Unsalted Hashes Too? – Intrepidus Group - Insight with my ipad and it went to an onswipe section of the site, now i wonder if this was a malicious site? , can anyone visit this site with an ipad and give any input?
