Hi,

have seen the same just recently. Around the same no. of attempts, every
one coming from a different host and all tries against the root account.

I haven't seen this before myself and I don't think it's generated by the
same ssh brute forcing malware practically every attackers seems to be
using. Anyone having followed up on this with the originating site and was
able to get the malware? (A colleague of mine is trying that right now but
the chances of getting the malware are slim ...)

Regards,
Andreas Bunten
