Today I looked up the most prolific botnets for the month of July. Earlier this year the grum botnet was disrupted. How have things changed since then? Here’s a look at the top 15 botnets hitting our networks for the month of July by total mail volume:
- Cutwail is the #1 botnet, which was not surprising. It usually occupies space among the top 3.
- Grum is not yet dead.
- Lethic is less prolific than it has been in the past.
- The gheg botnet is way down the list.
Other than that, there’s not much new here from my previous musings about botnets.
