Average Daily Botnet Traffic
|This chart shows the average amount of traffic we see to each botnet command and control (C&C) server we are monitoring daily. This is the actual bandwidth consumed by the bots as they check in with the controller and receive commands. This data is based on a sampled view of traffic, and shouldn't be treated as hard numbers, but can give you an idea of the rates of usage involved in running a botnet.|
Overall Malicious Activity, Top 10 Countries
|This chart lists the top 10 countries seen contributing to malicious activity online in the last 24 hours, as a percentage relative to total malicious activity in the same period. IP geolocation isn't perfect, so this data isn't exact, but we believe it should be roughly representative of the current global picture.|
Top 10 UDP Ports (logarithmic scale)
|This chart shows the top 10 UDP ports seen in sampled global Internet traffic in our most recent hourly data sample. This chart is on a logarithmic scale, so the difference between the top port (usually UDP/53) and the bottom port may be more significant than it appears to the naked eye.|
Sampled DNS Request Rate (hourly)
|Our insight into Internet traffic around the globe allows us to sample and estimate trends in Domain Name System (DNS) requests, one of the key pieces of Internet infrastructure. This chart provides a glimpse into that sampled rate over the course of seven days, aggregated hourly, for both TCP and UDP DNS requests (though the TCP request rate is so low as to be virtually impossible to see).|
Internet Malicious Activity Maps

Our contribution to Operation Ghost Click
[17 NOV 2011] On 09 November 2011, US law enforcement released details of a major series of arrests as part of Operation Ghost Click. Team Cymru is proud to have been able to add details of victim computers that were part of this criminal infrastructure into one of our daily feeds of data that is provided at no cost to providers around the world. These lists of affected IP addresses enable network managers to identify and remediate computers infected by malware that are taking part in criminal activities.
This has a direct impact on people: it disrupts criminals and improves the lives of legitimate Internet users everywhere; we're honored to have been able to contribute to this effort. Our great thanks to all who contributed to this team effort.
Unexpected and unsubstantiated blog post
[25 OCT 2011] A recent blog post appeared to draw the unsubstantiated conclusion that more than 760 organizations were compromised with some of the same resources used to hit RSA earlier this year. Team Cymru was one of the organizations named in the posting.
We have no evidence of compromise related to incidents at RSA or anywhere else. The source of the report, and those who revealed and posted it, didn't take the time to contact us, or to share incident details with us. Thus we are unable to investigate further. We hope that those who gathered this data will responsibly disclose it to the potential victims.
Please note that without more details on the methodology used to determine the list of organizations, and a scientific review of the same, it's not safe to assume that an entry on the list means either "victim" or "false positive". We've seen no data or methodology description that would support either case.
New Underground Insight: A Criminal Perspective on Exploit Packs
[05 MAY 2011] The Team Cymru Business Intelligence Team is pleased to announce the release of their latest paper, entitled "A Criminal Perspective on Exploit Packs". This paper chronicles the genesis and historical eveolution of the Browser Exploit Pack (BEP). We discuss our research into the installation and usage of 40 different packs. Most notably, the paper discusses dishonor among coding thieves and the entrenched practice of "statistics shaving". Finally, we examine the monetization, code protection, and overall effectiveness of the various packs. For full details, check out the whitepaper, and don't forget to look at the rest of our whitepapers as well!
Team Cymru moving to Florida
[04 MAY 2011] Team Cymru today announced that they are relocating their headquarters staff from Chicago, Illinois, to Central Florida over the summer. The majority of our Chicago staff will move and are excited at the prospect of continuing to use our insight to improve lives, but from a significantly warmer location.
