We see increased scanning activity, but it doesn't look like a
widespread worm:

    date    | sources | targets | flows
------------+---------+---------+-------
 2003-10-20 |    8058 |   10796 | 27206
 2003-10-21 |    3331 |    5908 | 11425
 2003-10-22 |    3660 |    7324 | 13989

 2003-10-29 |    3651 |    5171 | 10898

(Date, number of distinct source addresses, number of distinct target
addresses, flows AKA connection attempts -- incoming packets only, and
and the 2003-10-29 row is still increasing, of course.)
