urlhaus-filter and phishing-filter available as Snort and Suricata rules | Tested on Snort 2, Snort 3 and Suricata 6 | 2021-03-20 | 2021-04-05 |
|
Update (5 April 2021): The blocklists are also available in Response Policy Zone format.
urlhaus-filter and 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 and Suricata 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 already support them and there was no user request. I finally decided to go for it after the product announcement of AWS Firewall with its support of custom Suricata ruleset, plus incomplete support of URLhaus on Snort 2 ruleset.
Installation guide as follow.
