Some of the IPs will have an infection type, and these will only be for the HTTP bots or the Spam relays. As we’ve grown in size, so have our data sets, requiring us to change our storage technology and methodology. We had to make certain changes to the data sets and have required certain output changes, as well.
What does the C&C really mean?
The IP for the C&C could be a real command and control system that we are (or a partner is) monitoring either directly or passively. It could also be one of the many sinkhole servers that we and our partners operate. If it is a sinkhole server, this means that your IP address reached out and communicated somehow with our server. We cannot issue commands, nor can we control your system from our sinkhole server, since it is a mostly passive capture device. We only harvest the connection information and report it back out.
Why is the C&C set to “0.0.0.0” or blank?
This can occur for several different reasons.
- We may not have the C&C IP address, depending on the source of the data and the method of tracking. For example, you could have a drone IP labeled as Spam. Since we extracted the last hop from a Spam message, we do not know the controlling source and cannot report it out.
- In the instances where the capture point was our Sinkhole server, we are the C&C in this instance and there is no reason to include our IPs.
If we have the data, we will always include it in the reports. We filter nothing from the data we send out, except to ensure that you receive the data for your responsible area.
What does it really mean when something was tagged as “spam” for a drone?
When we collect Spam messages, the message headers can be almost completely falsified, except the last hop connection before it hits a Spam trap. These are those IPs we are reporting: the ones that somehow relayed or originated the message to the traps.
I found the IP you listed, but my logs show a few hours off. Is your time correct?
All of our logs are in UTC, but we only send out the first event for each IP. There could be dozens or hundreds in a day. Because of the quantity of events on a daily basis, it is not efficient to send out each and every event seen on an IP.
