> Update (5 April 2021): The blocklists are also available in [Response Policy Zone](https://dnsrpz.info/) format.
|
|
|
|
[urlhaus-filter](https://gitlab.com/curben/urlhaus-filter) and [phishing-filter](https://gitlab.com/curben/phishing-filter) are blocklists that target malware and phishing websites respectively. The blocklists are available in many formats:
|
|
|
|
- uBlock Origin (urlhaus-filter is bundled by default)
|
|
- Pi-hole
|
|
- AdGuard Home
|
|
- AdGuard (browser extension)
|
|
- Vivaldi 3.3+
|
|
- Hosts file
|
|
- Dnsmasq
|
|
- BIND
|
|
- Unbound
|
|
- IE9+
|
|
|
|
In addition to the above formats/software, they are now also available as [Snort](https://www.snort.org/) and [Suricata](https://suricata-ids.org/) IDS rulesets. Both Snort 2 and 3 are supported; a vast majority of Linux distribution have not support v3 yet and there are no official v3 binaries. Note that Snort 2 ruleset is not compatible with Snort 3 and vice versa.
|
|
|
|
I planned to create these IDS rulesets for a long time, but held it off because upstream [URLhaus](https://urlhaus.abuse.ch) already support them and there was no user request. I finally decided to go for it after the product announcement of [AWS Firewall](https://aws.amazon.com/blogs/aws/aws-network-firewall-new-managed-firewall-service-in-vpc/) with its support of custom Suricata ruleset, plus incomplete support of URLhaus on Snort 2 ruleset.
|
|
|
|
Installation guide as follow.
