MW malware sublist added to multi, replaces OB
by SURBL Announcement list [READONLY] 01 May '13

01 May '13

As announced last October, malware data has been moved from PH to a new list MW, taking the bit of OB, which was deprecated last year. Along with malware data, limited set of cracked hosts also has been moved from PH to MW, in part because cracked sites often have or can have malware on them. The bitmask bit 16 therefore is no longer used by OB, but is used by MW now. Please update configurations appropriately. For example in SpamAssassin, change: urirhssub URIBL_OB_SURBL multi.surbl.org. A 16 body URIBL_OB_SURBL eval:check_uridnsbl('URIBL_OB_SURBL') describe URIBL_OB_SURBL Contains an URL listed in the OB SURBL blocklist tflags URIBL_OB_SURBL net reuse URIBL_OB_SURBL score URIBL_OB_SURBL 0 0.785 0 0.122 to: urirhssub URIBL_MW_SURBL multi.surbl.org.

Heads up: Updates on two-level-tlds/three-level-tlds
by SURBL Announcement list [READONLY] 28 Jan '13

28 Jan '13

Dear SURBL community, Just a heads up that we added some more domains on the two-level-tlds/three-level-tlds files as available on the SURBL site. The updated files can be found at: http://www.surbl.org/tld/two-level-tlds http://www.surbl.org/tld/three-level-tlds We will add new domains to these files to reflect better detection of abused freehosting envirionments.

Deprecation of OB sublist, creation of MW malware sublist
by SURBL Announcement list [READONLY] 22 Oct '12

22 Oct '12

In order to keep improving SURBL data, we plan to reorganize some of the sublists inside the combined list multi as described below. OB -- OB sublist to be deprecated immediately Due to reduced effectiveness, SURBL will be deprecating the data in the OB sublist in a multi-stage process described below, with a the timeline at the end of this announcement. We will emptying the OB dataset beginning immediately. Since the current OB data are resulting in few detections, the effect of emptying the list should not significantly impact most production systems that are using the data. After the OB dataset has been empty for a period of time, we will be replacing bitmask bit 16 that OB currently uses with a new list described next. SURBL would like to sincerely thank the Outblaze team and their successor organization IBM for very kindly making the Outblaze data available to the SURBL community for several years. Special thanks go to Suresh Ramasubramanian and his colleagues for their many years of dedication in helping SURBL and the broader Internet community to stop messaging, botnet, malware, phishing and other forms of abuse. MW -- New malware sublist After some time with OB data emptied, the bitmask bit 16 formerly used by OB will be used by a new list MW which will consist of malware domains and IPs, most of which which are currently merged into the PH list. We had overloaded the phishing list PH with both phishing and malware data since they were somewhat related, but several users of SURBL data have expressed an interest in separate classifications for phishing and malware. Splitting those categories of data info separate sublists will make the distinctions between phishing and malware available for the whole SURBL community to use. Having a separate malware sublist should allow SURBL applications to make finer-grained, more accurate classifications and to perform better as a result. Some records may be on multiple lists. For example if a site has both phishing and malware, then it may be on both the PH and MW lists. Overlap between any datasets has been and will continue to be possible. Timeline: Deprecation of the OB dataset - Immediate Creation of the MW (malware) dataset - 1 May 2013 The documentation on the SURBL site will be updated the next few weeks to reflect the changes. It has not been updated yet. http://www.surbl.org/lists Recommended action: We recommend that SURBL application developers prepare to update their configurations according to these changes so they are ready when the changes are put into production on our name servers and zone files. Please direct followup discussion to the SURBL Discussion list.

ANNOUNCE: Some two-level-tlds accented characters changed to IDN
by SURBL Announcement list [READONLY] 04 Apr '11

04 Apr '11

Anthony Howe noticed that gcc was complaining about ISO 8859-1 accented characters used in the two-level-tlds file. With his kind help, we converted those to equivalent IDN representation. Diffs are: 278c278 < aéroport.ci --- > xn--aroport-bya.ci 893c893 < drøbak.no --- > xn--drbak-wua.no 1955c1955 < lea?gaviika.no --- > xn--leagaviika-52b.no 2835c2835 < osterøy.no --- > xn--ostery-fya.no 3554c3554 < tysvær.no --- > xn--tysvr-vra.no 3587c3587 < unjárga.no --- > xn--unjrga-rta.no 3650c3650 < vegårshei.no --- > xn--vegrshei-c0a.no As a practical matter this should have little operational impact since those domains are obscure and unlikely to be abused. Nonetheless, we thank Anthony for the correction.

three-level-tlds file added, abused hosts added to two and three level TLD files
by SURBL Announcement list [READONLY] 25 Feb '10

25 Feb '10

SURBL has created a three-level-tlds list that contains domains that should now be checked at the fourth level. It joins the existing list of two-level-tlds domains that should be checked at the third level. We also added some frequently abused web hosts into both of these TLD files, so they are no longer strictly CCTLD files, but should be able to function the same way for applications. We also moved the location of the files. For more information please see our Implementation Guidelines: http://www.surbl.org/implementation.html The new location of these files is: http://www.surbl.org/tld/two-level-tlds and: http://www.surbl.org/tld/three-level-tlds Please do not retrieve these files more often than once per day. They update only rarely. The old location will redirect to the new one for a while then go away eventually. Please update all SURBL applications accordingly. The TLD handling change is backward compatible, but there will be more detections if implemented. The updated TLD data in part come from: http://rulesemporium.com/rules/90_3tld.cf http://rss.uribl.com/hosters/hosters.txt http://publicsuffix.org/ https://wiki.mozilla.org/Gecko:Effective_TLD_Service http://mxr.mozilla.org/mozilla-central/source/netwerk/dns/src/effective_tld… http://svn.apache.org/repos/asf/spamassassin/branches/3.3/lib/Mail/SpamAssa… and ongoing but infrequent registry research.

RFC: Discontinuing rsync service of individual list zone files
by SURBL Announcement list [READONLY] 21 Dec '09

21 Dec '09

In March 2009 we stopped delegating public DNS service of individual list zones such as sc.surbl.org, ws.surbl.org, etc., since they are obsolete and all their data are included in multi.surbl.org. We would also like to stop rsync service for these files, again since their content is included in multi.surbl.org, which is the only zone anyone should be using. If anyone has feedback about this proposed change, then please contact us by email at rsync at our domain.
