Welcome to the Comprehensive Cybersecurity Blocklist, an essential tool designed to protect your network by preventing access from IP addresses and domains associated with cybersecurity threats. Our goal is to offer an up-to-date, effective solution to safeguard your digital environments against various cyber attacks.
This blocklist is a curated set of IP addresses and domains known for malicious activity. It is intended for use by network administrators, security professionals, and anyone needing to enhance their system's security posture against external threats.
- Unified Resource: A single, comprehensive blocklist for streamlined security management.
- Support for IPv4 and IPv6: Compatible with all modern network equipment.
- Frequent Updates: The list is updated daily to ensure protection against new and evolving threats.
The blocklist is divided into categories based on the type of threat. Here are some examples of what you might find on our list:
- Compromised Servers: IPs of servers taken over by attackers, used as part of a botnet or for other malicious activities.
- Botnet Nodes: Details of command and control centers, as well as individual bots used in large-scale attacks such as Distributed Denial of Service (DDoS).
- Phishing Domains: URLs identified as fraudulent, attempting to steal personal information under false pretenses.
- Scanners and Probers: IP addresses that scan for open ports and vulnerabilities, often a precursor to more serious attacks.
- Spam Sources: Identified sources of bulk unsolicited emails that may contain scams or malware links.
- Malicious Script Hosts: Domains known to host scripts that exploit software vulnerabilities or automate attacks against other systems.
If you encounter any issues or have queries regarding the blocklist, please raise an issue in the repository with a detailed description of your concern. Include the ID of the specific entry if applicable, to help us address the problem more effectively.
Feel free to reach out with any questions or contributions at blocklist@jamessawyer.co.uk.
The blocklist is generally updated on an hourly basis to reflect new threats and updates to existing entries. We recommend pulling updates as frequently as necessary to ensure your systems remain protected with the most current threat data.
