Re: FTP Probes from Taiwan/China

Has anyone seen a dramatic increase in FTP probes/scans/bad stuff from
certain IP blocks in Taiwan or China?  Specifically, 211/8, 61/8, and
202/7.  I'm logging over 7500 probes/hr right now.  Is there a new
exploit out or something?

Another network just surfaced:  210.82/15

I am getting lots of port 80'ish scans from those IP ranges.
and a few port 139, but I have not seen a port 21 (FTP) scan from anyone
in the last 30 minutes... while monitoring a /19 and a /20 locally.
