The first task the website will perform is to search through your contacts in Yahoo, MSN Hotmail and Gmail etc for people who are already registered with Twitter.
On its website, Amesys says its "strategic nationwide interception" system can detect email from Hotmail, Yahoo and Gmail and see chat conversations on MSN instant messaging and AIM.
The credentials have since been pulled from the web, but it turns out they weren't just for Yahoo accounts, as Gmail, AOL, Hotmail, Comcast, MSN, SBC Global, Verizon, BellSouth and Live.com login info was also pilfered and placed on display.
