3 Interpol “In the past, cybercrime has been committed by individuals or small groups of individuals. However, we are now seeing an emerging trend with traditional organized crime syndicates and criminally minded technology professionals working together and pooling their resources and expertise. This approach has been very effective for the criminals involved. In 2007 and 2008 the cost of cybercrime worldwide was estimated at approximately USD 8 billion. As for corporate cyber espionage, cyber criminals have stolen intellectual property from businesses worldwide worth up to USD 1 trillion.”
