Security Incidents: Unicode Logs with Ping Activity

[myrddin_e () hushmail com]

Would like someone to help me understand what is going on here... The 502 
error at the end end of these entries would indcicate failures, wouldn't 
they? I've been all through the logs on this box, and even thought at every 
attempt to copy c:\winnt\system32\cmd.exe to c:\inetpub\scripts\shell.exe 
shows a 502, it is there.

I'm looking at the times on the log entries and guessing that this was a 
manual attack.

Also, can someone please explain what is being attempted with these pings?
aaa.aaa.aaa.aaa
bbb.bbb.bbb.bbb
ccc.ccc.ccc.ccc.ccc
ddd.ddd.ddd.ddd.ddd 
are all unique addresses.
