Introduction

As security professionals we always are asked how large is the population of an infection. Conficker is no different from any other, and it seems that everyone wants to have some value to use for many different purposes. The press for impact, some vendors for FUD, and others to have a number to compare to other infections. The bottom line is that no one can give an exact number on any infection ever. If anyone ever states exact numbers, they either are controlling it, or are not being completely honest to themselves or others on the means of data collection. We can estimate a number based off of certain traffic types, but we make mistakes as often as anyone else. A lot of the malicious traffic can resemble other legitimate or malicious traffic which of course skews the numbers. On top of simple traffic analysis each threat provides its own unique mechanisms for tracking infection statistics. Each of these methods of course come with their own positives and negatives when discussing accuracy of the data. It is what that in mind that we wanted attempt to draw out some of the pro's and con's of our data collection methodology below.

So, it is with a lot of trepidation that we even show any values for conficker knowing that they will most likely be taken out of context and quoted by many.

Population Numbers

What the following tables show are the daily connections and unique IP's that have been connecting to our tracking systems. Many people equate one IP to one system, but that is not usually the case. If the system is behind a NAT gateway, it would represent dozens or hundreds of systems. If a system is mobile it could be reported several times in a single day under different IP's. And in today's world there are a very large number of mobile users which could inflate the number of connections and unique IP's that are tracked.

What does this really mean? The daily numbers should represent the potential maximum level of the infection, but in previous test cases usually prove to be much less than that maximum. So, take the range of 25% to 75% of the values that we display as the possible infection population and you will be close to the real value. And yes, this is a very large range, and you can see why we do not like to quote any numbers for infection populations, and why you will see very high and low numbers get quoted regularly depending on the purpose of the person making the quote.

One last note: we are publishing these numbers to give a better understanding of what we are tracking. We do not believe in shaming anyone related to these values, and is not our purpose in any way.

Data Details

These tables are updated daily from the tracking systems. They are updated only once a day.

These tables are specifically for the A+B infections.

This chart shows the rate of IP's being seen over time. Because of the great difference between the daily totals and the hourly, we are using two Y-Axis values. The Y-Axis on the left is for the daily totals, while the one on the right s for both the hourly lines.
