Ms Colleen Shannon - Code Red: Spread and Victims of an Internet Worm

Cooperative Association for Internet Data Analysis

2002-07-09

Computer Science Seminar Room, G1.15

On July 19, 2001 more than 359,000 computers were infected with the Code-Red (CRv2) worm in less than 14 hours. The cost of this epidemic, including subsequent strains of Code-Red, is estimated to be in excess of $2.6 billion USD. Despite the global damage caused by this attack, there have been few serious attempts to characterize the spread of the worm. To this end, we collected and analyzed data from a /8 network over a period of 45 days beginning July 2nd, 2001 to determine the characteristics of the spread of Code-Red. We begin our analysis with a look at the initial spread of Code-Red. We examine in detail the infection rate of the worm and its fit to an analytic model of worm spread. To understand the rate at which infected machines were repaired, we measured the patch rate of compromised machines during the subsequent month. We then take an in-depth look at the victims of the Code-Red worm by analyzing the properties of infected hosts, including geographic locations and diurnal patterns of infection. We also quantified the effects of DHCP on measurements of infected hosts and determined that IP address counts are not an accurate measure of the spread of a worm on timescales longer than 24 hours. Although most media coverage focused on large corporations, the Code-Red worm preyed upon home and small business users. Bio: Colleen Shannon is a staff researcher at the Cooperative Association for Internet Data Analysis (CAIDA). Her research interests include traffic measurement, characterization, and modeling, particularly with regard to network security and network application identification.
