Infection Period #2. Starting at 8pm EST on July 31 2001, the worm shows exponential growth; see these PNG plots:
During the day of July 19th, 2001, TRIUMF experienced an unprecedented number of probes from the Internet for port 80 HTTP service (Webserver). These are attributed to the Code Red worm, which attacks unpatched Microsoft IIS webservers.
At this time, the SANS incident handling centre set the Internet Threat Level to "Orange" (on a scale green, yellow, orange,red). On July 20th, the Threat Level was downgraded to Yellow.
Check out this page at CAIDA. It has some cool animations of the geographic spread of the worm.
For more information on the Code Red worm, please see:
The graph shows the number of probes to port 80 to addresses
within the TRIUMF domain where a webserver is not
running. These mostly represent scanning activity by the
Code Red worm.
For a logarithmic plot, showing tailing off of the numbers of scans since July 20, see codered.log.png (since 13 July), codered.log2.png (since 31 July). At 9am PDT on August 1, the log plot shows a straight line (exponential growth)
For a linear plot of probes since July 24, see codered3.png
