This is a list of rule groups of potentially suspicious hosts, which you can subscribe to from Little Snitch version 4.1 onwards.

These groups are generated from the raw host files on Steven Black’s unified hosts project.

Disclaimer: I make no claims or warranty for the veracity or accuracy of any of the source lists. In particular categorising something as “fake news” may be a matter of opinion. I just want to make them easier to consume from Little Snitch. I am not a lawyer. Use these at your own risk. You can always explicitly override false positives.

The rule groups

Each list has been split into two rule groups because they exceed the limit of a Little Snitch rule group.

This is a breaking change, because I didn’t want people subscribing to just the first chunk of a block list and thinking they have the whole thing.

This means you will have to resubscribe to all the rule groups for the list you want.

Unified (adware + malware)

Unified + fake news

Unified + gambling

Unified + porn

Unified + social media

Limits

Little Snitch has a limit of 200,000 entries per rule group. When I wrote Snitcher in 2019, the Steven Black lists had around 50k entries, so 200k seemed like plenty of overhead. But then this happened: Hopefully this is linear rather than exponential growth! The jags in the graph look like someone changing the criteria for different categories, so that chunks of hosts are suddenly included or excluded. Since Little Snitch has no concept of subscribing to a group-of-groups, I decided to split the lists at the 200,000 limit, which should keep us going for a while.
