[Full-disclosure] Spike in SSH scans

[Shaun]

I saw an unusually high volume of scans between 2200 and 0000 last night
on my residential connection. They all made their initial probe using
'mysql' as the user. On average it looks like each of them made around
15 attempts, which is fairly low, and points to a scanner smart enough
to recognize that it's been firewalled out.

So far, nothing out of the ordinary at work or on dedicated servers.
Maybe it's only targeting consumer connections? FWIW, my residential IP
is in 75.65/16.
