Surbl

This list contains mainly general spam sites (pills, counterfeits, dating, etc.). It combines data from the formerly separate JP, WS, SC and AB lists. It also includes data from Internet security, anti-abuse, ISP, ESP and other communities, such as Telenor. Most of the data in ABUSE come from internal, proprietary research by SURBL itself.

‍jwSpamSpy + Prolocation sites:

‍Joe Wein's jwSpamSpy program along with systems operated by Raymond Dijkxhoorn and his colleagues at Prolocation provide JP data. The resulting list has a very good detection rate and a very low false positive rate.sa-blacklist web sitesWS started off with records from Bill Stearns' SpamAssassin ruleset sa-blacklist but nowadays holds data from many different data sources.

‍SpamCop web sites:

‍SC contains message-body web sites processed from SpamCop URI reports, also known as "spamvertised" web sites. The reports are not used directly, but are subject to extensive processing. Entries in SC expire automatically several days after the SpamCop reports decrease.

Note that this list is not the same as bl.spamcop.net, which is a list of mail sender IP addresses.‍

‍AbuseButler web sites:

‍AbuseButler is kindly providing its Spamvertised Sites which have been most often reported over the past 7 days. The philosophy and data processing methods are similar to the SC data, and the results are similar, but not identical. Data sources for AbuseButler include SpamCop and native AbuseButler reporting.

Phishing data from multiple sources is included in the PH Phishing data source. Phishing data includes PhishTank, OITC, PhishLabs, Malware Domains and several other sources, including proprietary research by SURBL.

This list contains data from multiple sources that cover sites hosting malware. This includes OITC, abuse.ch, The DNS blackhole malicious site data from malwaredomains.com and others. Some cracked hosts are also included in MW since many cracked sites also have malware. Note that the above is only a sampling of many different malware data sources in MW. Malware data also includes significant proprietary research by SURBL.

If you get a result of 127.0.0.1 when doing a SURBL DNS query into the public nameservers, then it means your access is blocked. Please see SURBL's Usage Policy and sign up for SURBL's Sponsored Data Service (SDS).

For the Cracked (CR), Phishing (PH) or Malware (MW) lists or any cracked (breached) web sites, please be sure to remove and secure all phishing sites, cracked accounts, viruses, malware loaders, trojan horses, unpatched operating systems, insecure PHP boards, insecure Wordpress, insecure Joomla, insecure third party plugins, cracked SQL, insecure ftp passwords, password sniffers, etc., from the web site and all computers used to upload content to the web site before contacting us. If you need help, please contact a security expert to do a full security audit on the web site and all computers used to connect to it. Systems that are not properly secured may be broken into again.

Note that there has also been cracking of DNS control panels resulting in malicious subdomains being added to domains. Please also check and fully secure all DNS infrastructure for your domains. Please contact a security expert if you need help with this.
