Today i started to move my website to other host and noticed that all my downloads (i sell digital goods) was compressed to one file named hedefsite.com.tar.gz I started to search for it and i found that this is hacking tool http://pastebin.com/N9bgjWTP
I use strong passwords, and admin username is changed to other name for security reasons. I don't use any of in script mentioned wp plugins. So are we safe from thsi tool in newest wp version?
PS. in my website there also was left old scripts from eshop openCart, hackers maybe used it not WP, but i want to be sure that wordpress nows about this tool and we are safe.
