How to Use These Lists

These are standard text files and can be used with most modern firewalls, ad-blockers, and security tools.

🛡️ inbound.txt (Inbound Blocklist)

• What it is: A list of IPs/networks with a bad reputation for initiating malicious connections. This includes sources of spam, scanning, brute-force attacks (SSH, RDP), and web exploits.
• Use Case: Protect your public-facing servers and services (web servers, mail servers, game servers, etc.).
• How to use: Apply this list to your firewall's WAN IN or INPUT chain to DROP or REJECT all incoming traffic from these sources.

☢️ outbound.txt (Outbound Blocklist)

• What it is: A list of known malicious destination IPs. This includes C2 (Command & Control) servers, botnet controllers, malware drop sites, and phishing hosts.
• Use Case: Prevent compromised devices on your internal network (like a laptop or IoT device) from contacting malicious servers.
• How to use: Apply this list to your firewall's LAN OUT or OUTPUT chain to BLOCK or LOG all outgoing traffic to these destinations.

Self-hosted runners

The update.yml workflow takes a long time to complete. I run it on a self-hosted runner. If you fork this repo and want to use the same workflow, set up a self-hosted runner: Setup Self-hosted runners
