Re: Weird Traffic

["Jonathan Adams" <keirre.adams () gmail com>]

Well since the last post, I've scanned the drive for large files
(warez) nothing there...

aside from the proxying Im getting alot of weird (botnet I guess) traffic

looks like this:

The 64 address is a serial offender, I' ve over 700 hits from it in the logs
Appears to be in LA California, most likely a hacked server - it has
the normal ports open
"IP: 64.56.75.87 Location:
Los Angeles, CALIFORNIA, United States US (Vrtservers, Inc)"


The china stuff in my logs has just shifted to different IPs since the
last batch of update FW rules, but the traffic is high

This is definitely the source of my troubles.

I've blackholed the serial offending IP's but Im sure it will shift again.
