In reviewing the Top 10 Ports today at isc.sans.org/portreport.html I noticed that there is an unusual increase in activity on isc.sans.org/port.html.

The data that is being submitted indicates that we have gone from less than 100 targets a day to over 50,000 .  We would like to know what you are seeing.  Take a look at your network to determine if you are seeing this activity and let us know. It would be helpful if we could get some data captures so that we can take a look at the data and see what is generating the traffic to port 57886.  You can upload the captures to our website at isc.sans.org/contact.html
