To analyse the cna12 MySQL attacks, I had to install MySQL Express Server as the attacks were prematurely exiting when connecting to Dionaea. Extracting the binary files from the libpcap files was annoying, so I decided to change Dionaea so that it would automatically extract the binary files used in the cna12 attacks. Continue Reading

This post explains some measures that you can take to prevent the MySQL cna12.dll attacks from infecting your MySQL server. It follows on from a previous post which explains the attacks. If you find that a cna12.dll file or a piress user account keep reappearing on your MySQL server, then read on. Continue Reading

What if the attack caused the MySQL server to drop an executable file and pass control to it, or if the attack was exploiting a remote code execution vulnerability? I developed a Cuckoo package,, to allow me to dynamically analyse some of the effects of MySQL attacks. Continue Reading
