Odigo, the instant messaging service, says that two of its workers received messages two hours before the Twin Towers attack on September 11 predicting the attack would happen, and the company has been cooperating with Israeli and American law enforcement, including the FBI, in trying to find the original sender of the message predicting the attack.

Micha Macover, CEO of the company, said the two workers received the messages and immediately after the terror attack informed the company's management, which immediately contacted the Israeli security services, which brought in the FBI.

"I have no idea why the message was sent to these two workers, who don't know the sender. It may just have been someone who was joking and turned out they accidentally got it right. And I don't know if our information was useful in any of the arrests the FBI has made," said Macover. Odigo is a U.S.-based company whose headquarters are in New York, with offices in Herzliya.

As an instant messaging service, Odigo users are not limited to sending messages only to people on their "buddy" list, as is the case with ICQ, the other well-known Israeli instant messaging application.

Odigo usually zealously protects the privacy of its registered users, said Macover, but in this case the company took the initiative to provide the law enforcement services with the originating Internet Presence address of the message, so the FBI could track down the Internet Service Provider, and the actual sender of the original message.
