Oh, Behave! Who Made It to Rapid7 Labs' Naughty List(s) in 2019?

We all know jolly ol’ St. Nick just loves lists, which is an attribute he shares with the researcher elves here at Rapid7 Labs. Unlike Sir Kringle, our lists aren’t focused on normalizing the inevitability of a pervasive surveillance state nor intended to establish the acceptance of—and participation in—a global social credit system, but have more to do with cataloging (mostly) naughty aspects of internet infrastructure and activity through our core research platforms, Projects Sonar and Heisenberg.

The Labs team thought it might be fun to give folks a glimpse into who made it to some of our naughtiest lists in 2019 with a “year in review” look at insights gleaned from both our research projects.

The top 20 ‘naughtiest’ countries

There are many ways to track attacker activity, one of which is to look at which source country IPv4 assigned network blocks that traffic comes from. This doesn’t mean that said nation state is performing the attacking, just that poorly secured devices or servers and/or deliberate attacker infrastructure just happen to be found sitting on addresses in a country’s IPv4 blocks.

Our first two lists came from making distributions of the total and unique (by source IPv4 address) connections from each country. We plotted a dot for the counts for each day, for the entire year, which produced these ornament-like views of who led the top of the naughty charts for overall activity:
