"An international cybercrime investigation is underway into a sophisticated scam network that used email and fax to sell an Australian man's AU$500,000 property without his knowledge. The man was overseas when the Nigerian-based scammers stole his credentials and amazingly sold two houses through his real estate agent. He rushed home and prevented the sale of his second home from being finalized. Australian Federal Police and overseas law enforcement agencies will investigate the complex scam, which is considered the first of its kind in Australia. It is alleged scammers had stolen the man's email account and personal property documents to sell the houses and funnel cash into Chinese bank accounts. Investigating agencies admit the scammers hoodwinked both the selling agents and the government, and said they had enough information to satisfy regulatory requirements. The police did not rule out if the scammers had links to the man."
