The Abusix Exploit Blocklist is a real-time IP-based blacklist (or blocklist) that lists hosts exhibiting behavior specific to compromised systems, botnet infections, or anonymizing services such as proxies, VPNs, and TOR exit nodes.
Check if you are listed on Abusix Exploit Blocklist
The Abusix Exploit Blocklist is a real-time blacklist (or blocklist) that lists IP addresses exhibiting malicious behavior. This blacklist is generated by monitoring the activity of hosts connecting to a wide network of spam traps and partner mail services. It specifically targets IP addresses that behave like compromised hosts, botnet or virus infections, open proxies, VPNs, and TOR exit nodes. This type of activity is not typical of a legitimate SMTP server, making this blocklist effective at identifying sources of abusive traffic.
This DNSBL is used by Internet Service Providers, telecommunication companies, and hosting providers to filter incoming email and network traffic. It can also be used to check each hop in an email's 'Received' headers to trace the origin of a malicious message. Here is some technical information about this blacklist:
Blocklist Zone: exploit.mail.abusix.zone
Listing Type: IP addresses (both IPv4 and IPv6)
Return Code: A listing will return the code 127.0.0.4.
Listing Duration: A listed IP address will typically remain on the blocklist for approximately 5.2 days after the last malicious traffic was detected.
Who runs Abusix Exploit Blocklist?
The Abusix Exploit Blocklist is operated by Abusix, a company specializing in network abuse management, email security, and threat intelligence. Abusix aims to create a safer internet by stopping threats before they reach end-users. With a significant portion of cybersecurity threats traveling through ISPs and hosting providers, Abusix provides these organizations with solutions to secure their traffic and combat abuse, focusing on common threat vectors like email and network traffic.
How do I get removed and delisted from Abusix Exploit Blocklist?
If you find your IP address on this blacklist, the first step is to identify and resolve the root cause of the listing. Abusix does not want to penalize legitimate senders; the goal is to stop abusive behavior. Before requesting removal, ensure you have addressed common issues that lead to a blocklisting:
Review your mailing lists to ensure you are using confirmed opt-in and have protection against automated bot signups.
Check that your bounce management and subscriber engagement processes are working correctly.
Confirm you are not using purchased or appended email lists.
Secure any potentially compromised user accounts or infected computers on your network.
Once you have fixed the underlying problem, you can request to be delisted. The process is free, but it requires you to create an account to prevent abuse of the delisting system. You can request removal by visiting the Abusix Lookup and Delisting page. Follow the instructions to look up your IP, create an account, and submit a removal request. Delisting requests are processed immediately. While DNS queries will reflect the removal instantly, it may take up to five minutes for the change to propagate to all networks that use the blacklist.
What's the impact of being listed on Abusix Exploit Blocklist?
The impact of being on the Abusix Exploit Blocklist is considered medium. While not as universally adopted as some of the largest spam-focused blacklists, it is used by a significant number of ISPs, hosting companies, and other network operators. A listing on this blacklist will likely result in email delivery failures and blocked traffic to recipients whose providers use this data, causing a noticeable disruption to your email communications.
