Note: Given the widespread use of automated attack tools, attacks against Internet-connected systems have become so commonplace that counts of the number of incidents reported provide little information with regard to assessing the scope and impact of attacks. Therefore, as of 2004, we will no longer publish the number of incidents reported. Instead, we will be working with others in the community to develop and report on more meaningful metrics, such as the 2004 E-Crime Watch Survey. We welcome ideas and proposals for other collaborations in this area.
