Re: Snort blacklisted IP Addresses

["Joel Esler \(jesler\) via Snort-users" <snort-users () lists snort org>]

Yes.   That redirects over to Talosintelligence.com<http://Talosintelligence.com>.  That’s the list I am talking about

Subject: Re: [Snort-users] Snort blacklisted IP Addresses

You mean the sample IP blacklist system that we distribute from talosintelligence.com<http://talosintelligence.com>?

We've been emphasizing Domain convictions over IP convictions (because of the amount of false positives from IP 
convictions).  Which has resulted in the amount of IP addresses being convicted going down over time.

Snort Users,

We have been running an experiment last year, From May 2017 to October 2017, to monitor how blacklisted IP addresses 
used by snort evolve over time. We observed a sharp decrease in the number of blacklisted IPs around 21 June 2017. This 
is also complemented by our study using suricata IDS. Could anyone suggest, as to what exactly happened around that 
time which caused this sharp decrease in the no. of blacklisted IP addresses.
