Security Incidents: Animal Rights Hacktivist Group?

[ciso () hushmail com]

This is my second attempt at posting this.  For some reason the last post had a weird URL in it.  The activity has 
increased today we had a system defaced that was at latest patch level AFAIK.  The defacement message simply said;  
"HALL was here"

Has anyone seen any activity from an animal rights "Hacktivist" group over the last few weeks? I am the Security 
Officer for an organization that runs a number of animal related web sites and we have seen multiple attempts and even 
threats placed into our IIS logfiles in the form of invalid requests. 


"www.mycompanysitesubdomain.com/hall*will*0wn*j00" 
"www.mycompanysitesubdomain.com/free*the*little*animals" 


Is one such examples. They haven't cracked us yet but we have recieved multiple threats from a group known as "hall" 
which according to the anonymized email our CEO recieved stands for "Hacking for AnimaLs Lives" 


Has anyone else seen or heard anything from this group?
