SUMMARY: Botnets are degrading Website performance and preventing real people from visiting your Websites. Here is a brief update on the problem and some measures you can take to block one specific botnet operated by SEMalt.
You may know by now that the SEMalt “service” has been probing Websites with fake traffic generated by botnets. The problem with fighting botnets is that they come from everywhere. Many of the compromised nodes are Web hosting servers hiding in the cloud or in far eastern and European data centers. We see them coming out of Africa, South America, and even New Zealand. US military networks are compromised and rolled into the swarm every few months.
