[Full-Disclosure] Few n00b questions about this phatbot thing

[Sean McAllister]

So, as I understand it, this Phatbot is a complex black-hat tool that's 
used to create a "botnet"  of hacked computers that can be used for 
DDOS, stealing passwords, credit cards, and a plethora of other things?  
Has anyone ever found out who wrote it in the first place?  I can't 
imagine it has any benign use, just curious where things like this come 
from.
