Alex, Thank you for your reply,
However both 1, 2 & 3 for the same event not different events, the problem is that during a pentest I would never know what this password could be.
The attack in general is named password spray attack. could be used on different protcols, ssh, rdp, rlogin and any web application that can accept usernames and passwords, and so on. On Wednesday, May 16, 2018, 10:37:02 AM PDT, Alex McDonnell <amcdonnell at sourcefire.com> wrote:
You can do number 1 yourself using the detection_filter rule option. For number 2 you have the details of what that is, but unless you know the password, you can't detect the same password being used over and over.

Hello Snort Team,
I have came across something that you might be able to help me in,
We had a pen testing project, and we had a recommendations of applying rule to detect password sprays,
What happened is that the pen tester was able to run a script that send multiple sessions to login to multiple machines using the different usernames but with the same password, till he was able to login.
I need a rule that can detect the following:
1) If multiple login sessions was initiated from the same machine -same source ip- within low time frame.2) It was using different usernames but all used the same password.3) It was not destined to one machine that is why this ip was not locked out.
I would appreciate if you can guide me to get this rule implemented.
