SSH brute force password guessing attacks aren't really anything new. They have been going on for quite some time and whilst early July there was a small dip things seems to be getting back to normal.  One of our readers (thanks Robert) though noticed that the SSH brute forcing is coordinated between a number of IP addresses (118.97.8.28, 125.210.209.152, and 161.200.184.4).  If you have SSH open to the internet (honeypot or real) and you are able to share some log files I'd be interested to take a look at them.  Please upload them using the contact form or send them directly to markh.isc@gmail.com.

Log files will look something like this.
