I can't force the abuse contact to do anything. If you don't try something, you're just as complicit.
Fail2Ban with custom rules and actions is what I'm working on. Just because it is a dynamic pool doesn't mean people don't perpetually have the same IP. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com ----- Original Message ----- From: Ken Hohhof via Af <[email protected]> To: [email protected] Sent: Tue, 02 Dec 2014 09:27:58 -0600 (CST) Subject: Re: [AFMUG] 1. Netflix 2. Hacking Just when you put all that effort into it, and talk about throwing violators into a BGP blackhole, and forcing abuse contacts to take action, it seemed inconsistent with the reality. Plus the fact that a lot of those will be dynamic pool addresses. If you’re talking about something like Fail2ban and blocking SSH for 60 minutes, that makes sense. SSH and RDP dictionary attacks are a big problem, as are DNS amplification attacks. But rarely does the source IP actually identify who is behind the attack, just one of millions of bots. It seems a futile exercise to block them one IP address at a time. From: Mike Hammett via Af Sent: Tuesday, December 02, 2014 9:10 AM To: [email protected] Subject: Re: [AFMUG] 1. Netflix 2.

Netflix 2. Hacking You do understand most of those IPs will be infected computers with a bot doing the scanning, not a bad guy sitting at his own computer, right? As far as customers, we tell them they need to at a minimum have Microsoft Security Essentials or the free version of a commercial AV. If they ask for a recommendation of a commercial AV product, we tell them we use ESET. Nothing will protect someone who engages in risky online activity or clicks before thinking. Those people need a good local computer shop (not Geek Squad) to rescue their computer and data and to install security software. And amazingly, I still need to tell people that securing their WiFi is not optional, and 1234 is not an acceptable email password.

Currently I firewall all IPs that touch my honey pot IPs or attempt SSH at my edge. No need to have any of them on my network. I'm implementing a method to bring all servers, routers, switches, etc. back to a central syslog where I run my analysis there. That will then capture the more distributed scansattacks. Other than a whitelist, violators will be thrown into a BGP blackhole. It'll also fire off an e-mail to the RIR registered abuse contact. If you're doing any sort of trickery or trickeration (intentional via script kiddieworse or unintentional via malware), I don't want simple scans escalating into something more complex and possibly more damaging. You do the simple stuff, into the blackhole you go. I do understand that the abuse contact on the other side isn't likely to do much, but for the networks that will take action, I'd like to give them the information to do so. Plus if enough people do it, the abuse contacts are going to have to do something. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -------------------------------------------------------------------------------- From: "Tyson Burris @ Internet Communications Inc via Af" <[email protected]> To: [email protected] Cc: [email protected] Sent: Tuesday, December 2, 2014 8:28:16 AM Subject: [AFMUG] 1. Netflix 2. Hacking Two questions for the group this am. 1. Are you setting burst limits for Netflix or other streaming video services on your network routers? If so, what rate are you limiting it at? 2. With 97% of the US networks now Hackable, what are you doing on your side and advising customers to do? Meaning… what front line defenses are you taking and what software and/or hardware protection are you recommending to your customers? (It would appear that the majority of hacks these days are actually Malware infections inside the network - Employee related errors) Put your 2 cents in.
