The Russian Business Network is an ISP in St. Petersburg allowing for hosting of 'anything'.

"The Russian Business Network sells Web site hosting to people engaged in criminal activity, the security experts say.

Groups operating through the company's computers are thought to be responsible for about half of last year's incidents of "phishing" -- ID-theft scams in which cybercrooks use e-mail to lure people into entering personal and financial data at fake commerce and banking sites.

One group of phishers, known as the Rock Group, used the company's network to steal about $150 million from bank accounts last year"
