2023-02-21 ioc2rpz community service update

  ioc2rpz community cares about your privacy and reducing number of unnecessary communications. The service is evolving and we have to post notifications about maintenance, deprecated or new features and feeds.

  This this release ioc2rpz community will start emailing service notifications and news. If you don't like to receive them, you have an option to opt out in the settings.

  Just to recap, last year we added 2 new feeds: "blox-ukraine-russia-conflict.ioc2rpz", "hblock.ioc2rpz" and early this year an integration with AWS Route 53 DNS Firewall (and actually Pi-hole).

  Later this month we will be releasing 3 new feeds - stay tuned for the updates.

  The following community portal upgrade will be focused on removing inactive accounts. You will receive an email notification if your account is scheduled for removal. The details will be posted with the feature release.

2023-01-17 ioc2rpz community feeds for AWS Route 53 DNS Firewall

I'm happy to announce a tight integration of ioc2rpz community portal with AWS Route 53 DNS Firewall.

With Route 53 Resolver DNS Firewall, you can filter and regulate outbound DNS traffic for your virtual private cloud (VPC). To do this, you create reusable collections of filtering rules in DNS Firewall rule groups, associate the rule groups to your VPC, and then monitor activity in DNS Firewall logs and metrics. Based on the activity, you can adjust the behavior of DNS Firewall accordingly.

ioc2rpz community provides OSINT based filtering rules via files on AWS S3. You will need to periodically update Route53 domain lists (e.g. with a lambda function).

The integration requires a subscription which is available on AWS Marketplace. There are 4 tiers: free, core (includes free), essentials (includes core), standard (includes essentials) with a minimal price tag (like a donation). 

2022-09-16 3 years anniversary!

ioc2rpz 2019 vs 2022

I'm a bit late with my post but I want to share that in August the ioc2rpz community website (https://ioc2rpz.net) celebrated its 3 years anniversary.

Back when it had just 5 feeds with about 300k rules and now the community portal serves 18 feeds with over 13M rules not counting user defined TLD and country feeds. The community feeds (mostly based on OSINT) include malicious and phishing websites, adult content, ads and tracking domains filters.  Bfore.Ai's crime prevention predictive feed protects against newly registered, potentially phishing domains.

If you are interested in some statistics, the community website serves users from all continents except Antarctica (I wish that someone can spin up RpiDNS here :), 41 countries and 109 locations. The most downloaded feeds are: dga-360.ioc2rpz, doh.ioc2rpz, phishtank.ioc2rpz, urlhaus.ioc2rpz, blocklist-malicious.ioc2rpz and notracking.ioc2rpz

The community is non-profit and kind of my hobby so I don't really have a lot of time for maintenance. Luckily ioc2rpz technology (http://ioc2rpz.com, my open source project) was built on Erlang and robust enough so it doesn't really require a lot of care. If you want to know how to deploy it in your enterprise/ISP DM me.

The community is open for new users and if you want to protect your home, home office or even office a Raspberry Pi with community feeds can easily handle this task.

2022-06-01 New DNS Firewall feed - hblock.ioc2rpz

hBlock feed is a domain based feed which blocks ads, tracking scripts and malware. The feed is a compilation from multiple sources like adaway.org, AdBlock, AdGuard, DandelionSprout, EasyList, uBlock, Phishing Army etc. The feed is maintained by https://hblock.molinero.dev.

2022-03-07 New DNS Firewall feed - blox-ukraine-russia-conflict.ioc2rpz

New DNS Firewall feed blox-ukraine-russia-conflict.ioc2rpz protects against malware, phishing, suspicious domains related to the war in Ukraine. It is provided by Infoblox Threat Intelligence Group. Details can be found in this cyber threat advisory.

2021-11-16 covid19.ioc2rpz feed is deprecated

The Covid-19 Cyber Threat Coalition has ceased operations. They are no longer maintain the blocklist. The feed will be removed by 2021-12-01.

2021-11-02 New DNS Firewall feeds: oisd-basic.ioc2rpz, oisd-full.ioc2rpz

ioc2rpz community portal just got 2 new DNS Firewall feeds powered by oisd:

  • oisd-basic.ioc2rpz is a domain feed to block ads/trackers. It prioritizes functionality over blocking. 
  • oisd-full.ioc2rpz is a  domain feed to block ads, (mobile) app ads, phishing, malvertising, malware, spyware, ransomware, cryptojacking, scam etc. It also blocks telemetry/analytics/tracking where not needed for proper functionality. 

The feeds do not interfere with: Torrent, Warez, Porn, Crypto Exchanges, News Satire, Slickdeals (or shopping sites in general), Google (shopping), Facebook, Twitter, Snapchat, Link Shortners, Affiliate/Tracking Links, Gambling, Surveys, etc. but you aways can use other feeds to block undesired content.

2021-10-11 New DNS Firewall feed - bforeai.ioc2rpz

ioc2rpz community partnered with Bfore.Ai to introduce a new threat feed and make the whole world a bit more safe and secure.

Bfore.Ai is the first predictive threat feed in the market, the patented AI technology combined with hyperscale observation infrastructure predicts malicious domain names as their behaviour changes well before any other security solution or threat intelligence.

bforeai.ioc2rpz community feed includes malicious domains with the highest confidence score (less than 0.5% false positives) and up to 6 months of data. The community feed is degraded by a variable delay between 2 and 4 weeks (after the initial prediction). 

A live Bfore.Ai feed with more than 7M indicators and no time-limit is available commercially and it also includes benign domains for whitelisting, if you would like to trial it feel free to contact (https://bfore.ai) directly. Bfore.Ai feeds are available via API and ioc2rpz can help you to convert it to a DNS Firewall feed.

2021-08-06 ioc2rpz community celebrates 2 year anniversary

ioc2rpz feeds

Two years ago @ BlackHat 2019 and Defcon 27 I introduced the ioc2rpz community. The community is powered by ioc2rpz (http://ioc2rpz.com) and provides DNS Firewall feeds free of charge. The feeds are based on OSINT and protect against malware, block ads & trackers and filtrate adult sites. 

In 2013, when I joined Infoblox, I learned about DNS Firewall and I was able to evaluate only Infoblox's feeds. I tried to find any other free feeds but I was out of luck. There were only a few vendors who provided DNS Firewall feeds only for a fee. 

Late in 2017 I started working on ioc2rpz technology and to promote it as well as educate the community on DNS Firewall in 2019 I created the ioc2rpz community. Back then the community offered 3 feeds to block malware, ads & trackers with about 300k rules. During the next 2 years I added new feeds, custom feeds and RpiDNS - a provisioning script and management user interface intended to run on Raspberry PI.

Early this year the project and the community portal got a first sponsor which helps me to cover some costs to run the service.

Right now ioc2rpz:

- maintains 13 feeds with about 11 million rules, which you still can use on a beefy Raspberry PI 4/8Gb at your home (can your NGFW do the same?). Top 5 RPZ community feeds includes: dga-360.ioc2rpz, doh.ioc2rpz, phishtank.ioc2rpz, malicious.ioc2rpz, notracking.ioc2rpz;

- provides the service to more than 50 members from 5 continents, 25 countries and 70 locations.

This proves that ioc2rpz can serve in an organization of any size. If you use TIP, subscribed for TI or generate your own TI, ioc2rpz can help you to transform your DNS server (if it supports RPZ) to a DNS Security layer.

I'm looking forward to introduce new features soon, to serve more community members and make this world a bit safer and secure.

You are welcome to join the community (https://ioc2rpz.net).
