Subject: Re: Need help to find web server attacks signature
More weird stuff beginning, we see some HTTP GETs which
contains these information :
Accept: */*
Host: website.domain.com
User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)
-------: ----:----------------------
----------: -----
We got this via tcpdump
There is no other HTTP information.
2 headers are "hidden" and replaced with "-" char.
It looks like a bot (GET many times on many pages) and the
source is in this block :
81.62.0.0 - 81.62.255.255
BLUEWINNET
which is not the same as the one used for our attack yesterday.
Any thoughts on these "hidden" HTTP headers ?
Thanks again
