I had to collect and put your responses from the mailing list into
this email, because I didn't get the reply messages in my email.
Anyway, What I was trying to accomplish was to write a rule that fires
when executable files are downloaded from any web server. For that, I
put .exe file in a web server and requested that file via httpfrom the
machine that runs Snort. After removing the
"flow:to_server,established" from the rule, the rule fired but from
your responses, I think I was not doing it the right way. Could you
suggest me a better way? Also, in which rule files are the emerging
threat rules 2000419 and 2015744?
-Thanks all guys
This is the response from waldo kitty.
FWIW: this rule will not detect .exe files only... what it detects is the
content of ".exe" in any traffic being *sent to a server*...
this post should fire this rule if snort is looking at your mail server's
connection when this message arrives... in fact, every message in this thread
should have fired your rule when they hit your smtp server if snort is in the
right place to see it...
The VRT ruleset contains rules looking for PE files also...
