IOC feeds

[the_rock]

Hey boys and girls,

Happy Friday and weekend 🙂

Just figured would share some IOC feeds I put together in my lab, I counted and there is about 2000 known bad IPs that are blocked via all of them together, so hopefully it can help others.

If anyone has any others to share, please do so. FYI, you do need either AV or AB blades enabled to use IOC feeds and for best results, I recommend R81.20 version, as it also lets you test the feeds from smart console.

I truly believe everyone should do this method, as lets be honest, with ever evolving threats from the Internet, who has the time to manually keep updating bad IPs to be blocked? I will take a wild guess and say probably no one lol

Best,

Andy

Apologies, forgot to add 2 files I also used. This gives good example of what CSV file would look like.

[CaseyB]

Thank you for sharing! I have been looking for more of these to add to our current roster. 

[the_rock]

Very welcome, happy to help. Unlike Ed Sheeran's song "Perfect", this is far from it, but its something lol

Best,

Andy

[the_rock]

I will keep updating as I find more

Forgot to mention the most important one...duh : - )

Andy

secureupdates.checkpoint.com/IP-list/TOR.txt

 

[delToro1]

Hello mates, I usually use the following open source project:

https://github.com/stamparm/ipsum 

It sumarice malicious IP between different lists. It create lists based on the ocurrence of the IP and categorice en levels.

I have configured this IOC in my lab and it's working fine. The level 3 list has over 17K malicious IPs. From R81.20, the way of using network feeds in the access control policy, for me it is more granular.

testing network feedPolicy access rulebaseblock event Network feedUpdate Event Network feed

Best regards! 😉

[the_rock]

Wow, nice one! Let me test it in the lab later and report back.

Andy

[the_rock]

Just installed policy, so let me give it some time to see if there any hits. Though its just a lab, but it is in Azure, so Im sure it will get some traffic : - )

Andy

[the_rock]

Btw, I see the same link but level 2 has almost 35K IP addresses, that is fantastic, thanks for sharing!

Andy

[delToro1]

No problem ;). I detect that lvl 1 has some false positives, IP addresses from onedrive or sharepoint service that are legit. For me, the lvl 3 is OK, because  the IP must appear at least in 3 lists.

@the_rock , of course, thanks for sharing a lot of materials and resources for IOC. 🙂

[the_rock]

well thank you!!

Andy

[CaseyB]

The IPsum (lvl3) seems to be the most effective so far. We've dropped over 750 connections since I added it this morning. No one internally has tried to reach out though, so that's good.

The Emerging Threats one also has had a good amount of hits.

[the_rock]

Agree, same here!

[the_rock]

I see that when using network feeds, you dont technically need to have av or ab blades enabled, so thats definitely a plus right there and works beautifully.

Andy

[mrflow1]

@delToro1 @the_rock @CaseyB

What could be the impact of this level 3 feed at the resource level?

Is this feed injected like the iocs_feeds directly into the antivirus blade or do locally loaded iocs work better in terms of performance?

We have a cluster that has suffered a lot from CPU issues so I would be concerned that it will affect us even more.

[PhoneBoy]

If you're using R81.20 or above, the performance of ioc_feeds will be better since it uses the same infrastructure as Network Feeds, which is designed to handle at least 2 million IoCs.

[the_rock]

In R81.20, I had not noticed any issues at all.

Andy

[CaseyB]

I haven't noticed any performance impact on with our production cluster.

[majkel]

This one doesnt work with IOC_Feed object. I can see that the list is fetched but not applied and generates a error in HCP saying it cant be reach but thats not true since the list is fetched and stored in ioc path on the gws.
