Re: Code Red gone to sleep?

CR's 10/1 exit was predicted by some of the analyses of CR.

From http://www.incidents.org/react/code_redII.php ...

"Before each attempt to connect to a new target, the worm
checks the local time to see if the year is less than 2002
and if the month is less than 10. If either of these checks
return false, then the worm ceases the propagation cycle
and reboots the server. Note that this implies that all worms
will cease propagating by Oct. 1, 2001."

Hi folks,

      We were discussing on the Early Bird Developers list that none of
us have seen any Code Red scans since September 30th.  This can only mean
one of four things:

      1.      Code Red has "gone to sleep,"

      2.      Code Red committed ritual seppuku and rm'd every box it
              previously infected,

      3.      Nimda has taken over all previously infected Code Red
              systems[*],

      4.      All the automated intrusion attempt notices finally paid
              off and affected sites have finally shut their infected
              systems down.

      While I'd like to believe that the silence is due to option #4,
experience leads me to believe that options #1 and #2 are most likely, and
option #3 is a close runner-up.
