Hi.
Just a note I might have missed in the message traffic:
Those using grep/etc looking for .ida? in the IIS Logs will be missing some entries.
These are also showing up with "?" replace by a "," and a leading _space_ for
the Ns - also the ending is different. A "," has been added after the "a"
in010801.log:206.128.108.248, -, 8/1/01, 14:41:53, W3SVC24, XXXXX, xxx.xxx.xxx.xxx, 750, 4039, 604, 404, 2, GET, /default.ida, NNNNNNN
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u9090%u8190%u00c3%u0003%u8b00%u531b%u53ff%u0078%u0000%u00=a,

Is IIS transposing this?
I have these in different logs:
.ida?NNN...
.ida, NNN...
.ida NNN...

This is just for the IIS logs.

I you use the SNORT Rules Jim Forester posted a bit ago, it _should_ get all
variations, yes?
