Ya, but the way methods used to hack MySQL might be valid in the Unix world ao care should be taken. Of course, anyone who leaves the default administrator password on their database pretty much deserves to be rooted.
LOL ! Yeah, I agree.
This was a brute-force method for compromising the servers. Keep strong passwords, and you should be OK.
Basically, what this thing does is keep a list of common passwords and just tries them all until one works. Use non-dictionary, mixed-case, alphanumeric/symbolic passwords and you should be fine.
