Greetings!

Our computers running SSH daemons have logged attacks. The attacks begin
with a scan logged "Did not receive identification string from x.x.x.x",
followed approximately 15 minutes later with "Illegal user " or " Failed
password for root". 

Does anyone have information or documentation about this scan/attack?
Following is a list of Illegal users:
# cat secure.4 | grep "193.24.213.216" | cut -d " " -f6-12 | grep "Illegal"
| cut -d " " -f 3
