The Russian Business Network (commonly abbreviated as RBN) is a multi-faceted cybercrime organization, specializing in and in some cases monopolizing personal identity theft for resale. It is the originator of MPack (software) and the operator of the Storm botnet. The RBN, which is notorious for its hosting of illegal and dubious businesses, originated as an Internet Service Provider for child pornography, phishing, spam, and malware distribution physically based in St. Petersburg Russia. More recently it has developed partner and affiliate marketing techniques in many countries to provide a method for organized crime to target victims internationally.
