Unknown user agent in my logs...




Beginning just after 18:00 this evening, my Apache access log began to show
hits every few seconds from the same source IP.
Other than time, all lines appear to be the same... (sample given below).

Hits continued until I blocked the source IP (via iptables). My router shows
the incoming attempts continue at the same rate (but iptables is dropping
the packets as they reach that machine).

I'm wondering if anyone has experience with the User Agent shown in these
log entries. Google hasn't helped me at all (maybe my Google skills are
lacking...).

I suspect a hacked machine, especially since they apparently haven't noticed
I have blocked them; but, I wonder, hacked with what???
