Check out my other filters:

URL-based

Import the full version into uBO to block online and offline malicious websites.

Lite version includes online links only. Enabled by default in uBO >=1.28.2

Note: Lite version is 99% smaller by excluding offline urls. The status of urls is determined by the upstream Abuse.ch. However, the test is not 100% accurate and some malicious urls that are otherwise accessible may be missed. If bandwidth (9 MB/day) is not a constraint, I recommend the regular version; browser extensions may utilise HTTP compression that can save 70% of bandwidth.

Regular version contains >260K filters, do note that uBO can easily handle 500K filters.

If you've installed the lite version but prefer to use the regular version, it's better to remove it beforehand. Having two versions at the same time won't cause any conflict issue, uBO can detect duplicate network filters and adjust accordingly, but it's a waste of your bandwidth.

AdGuard Home users should use this blocklist.

Youtube compatibility

AdGuard format may have less youtube issue.

URL-based (AdGuard)

Import the full version into AdGuard browser extensions to block online and offline malicious websites.

Lite version includes online links only.

URL-based (Vivaldi)

Requires Vivaldi Desktop/Android 3.3+, blocking level must be at least "Block Trackers"

Import the full version into Vivaldi's Tracker Blocking Sources to block online and offline malicious websites.

Lite version includes online links only.

$TTL    86400   ; one day
@       IN      SOA     ns.nullzone.loc. ns.nullzone.loc. (
               2017102203
                    28800
                     7200
                   864000
                    86400 )
                NS      ns.nullzone.loc.
                A       0.0.0.0
@       IN      A       0.0.0.0

Issues

This blocklist operates by blocking the whole website, instead of specific webpages; exceptions are made on popular websites (e.g. https://docs.google.com/), in which webpages are specified instead (e.g. https://docs.google.com/malware-page). Malicious webpages are only listed in the URL-based filter, popular websites are excluded from other filters.

Popular websites are as listed in the Umbrella Popularity List (top 1M domains + subdomains), Tranco List (top 1M domains), Cloudflare Radar (top 1M domains) and this custom list.

If you wish to exclude certain website(s) that you believe is sufficiently well-known, please create an issue or merge request. If the website is quite obscure but you still want to visit it, you can add a new line ||legitsite.com^$badfilter to "My filters" tab of uBO; use a subdomain if relevant, ||sub.legitsite.com^$badfilter.

This filter only accepts new malware URLs from URLhaus.

Please report new malware URL to the upstream maintainer through https://urlhaus.abuse.ch/api/#submit.

Cloning

Since the filter is updated frequently, cloning the repo would become slower over time as the revision grows.

Use shallow clone to get the recent revisions only. Getting the last five revisions should be sufficient for a valid MR.

git clone --depth 5 https://gitlab.com/malware-filter/urlhaus-filter.git
