I noticed the same thing starting yesterday. On the surface it
appears to be a distributed attack from a botnet. Attempts are made
at 2-3 minute intervals. At a glance, they look like random IPs, but
out of 436 attempts since yesterday evening, there are only 198 unique
source IP addresses.

Has anyone checked out what data they are sending for a password?
