This also happened to my wordpress blog. The plugins were all disabled, the pages showed up as posts, and the admin password was changed.
The attacker was also able to upload a new theme in the wp-content dir. They were also able to explore the file system using the ‘dira’ parameter.
The same ro8kfbswmag.txt was placed in /tmp/
The initial attack showed up in the access logs
