Only cloud.SpamRankings.net ranks by
(although Spamhaus does ISPs).
* The traditional top-10 ASN www.SpamRankings.net has one peer comparison, for medical organizations, but cloud.SpamRankings.net has as many as there are two-letter NAICS codes.
Only cloud.SpamRankings.net and Spamhaus use composite rankings from multiple sources.
Only cloud.SpamRankings.net, SpamRankings.net, and Spamhaus explicitly use multiple spam blocklists as sources and in rankings.
Only Spamhaus includes a mug's gallery of individual spammers, ROKSO.
Only cisco includes clickable maps.
Includes for each entry rank, name, and score, for five different scores all in one table: infections, spam volume, network infected, per-capita infections, and per-capita traffic.
Includes country two-letter ISO-3166 code, "listings", percentages, rank, traffic with percentage, spams/bot, Size(K), Infection percentage, total numer of Internet users, and percentage of Internet users that are infected.
“"Listings" is the number of unique IPs at the corresponding country have been listed as infected by the CBL over the past 10 days.”
This is the closest CBL ranking to the cloud.SpamRankings.net organizational rankings. The statistics are similar to those for CBL Country.
Includes a handy clickable map. Rankings do not include a rank number, but do include a country flag, name, and a score, which is "Estimated Spam Magnitude". Each country is clickable to detail on spam sending networks within that country. Each header is also clickable to sort by that header's column.
Rankings do not include a rank number, but do include a name, a score, which is "Daily Magnitude", a percentage volume change with a red up arrow or a green down arrow, and a count of "Domains". Each network name is clickable to a list of domains with monthly magnitude and a map. Each header is also clickable to sort by that header's column.
Includes a handy clickable map. Rankings do not include a rank number, but do include a country flag, IP address, hostname (where known), network owner, and a score, which is "Daily Magnitude", a percentage volume change with a red up arrow or a green down arrow, "Email Rep." which usually seems to be "Poor", and often a link to a map. Each address, hostname, and network owner name is clickable to further detail. Each header is also clickable to sort by that header's column.
Includes for each entry rank, name, and score, which is "Number of Current Live Spam Issues".
“Most of the world suffers from the spam problem. However, some countries do little to deter spammers from operating within their borders. These countries become safe havens for the spam operations that plague everyone else, including their own nationals.
Countries with the highest number of spammers operating within their networks are usually those with poor or non-existent spam laws.”
It can't be quite that simple, since the U.S. has the CAN-SPAM act.
Includes for each entry rank, name, and score, which is "Number of Current Known Spam Issues".
“The networks listed on this page knowingly provide service to criminal spam gangs and ignore spam reports from anti-spam systems and Internet users. These networks are defacto Spam Havens from where spammers operate freely and with the full knowledge of the network administrators and the executives. In the name of profits, these ten networks turn a blind eye to criminal spam gangs on their networks.”
Interestingly, #1 Chinanet on this list as of 10 November 2013 almost always shows up at or near the top of our PSBL volume rankings.
“Up to 80% of spam targetted at Internet users in North America and Europe is generated by a hard-core group of around 100 known professional spam gangs whose names, aliases and operations are documented in Spamhaus' Register Of Known Spam Operations (ROKSO) database.
This TOP 10 chart of ROKSO-listed spammers is based on those Spamhaus views as the highest threat, the worst of the career spammers causing the most damage on the Internet currently. Spamhaus flags these gangs and individuals as a priority for Law Enforcement Agencies.”
This list may be very useful for law enforcement, but the rankings by cloud.SpamRankings.net may be more directly useful in ejecting spam (whether from botnets or snowshoe) from your organization.
This is one basis of Spamhaus' list of The World's Worst Spammers.
“The Register of Known Spam Operations (ROKSO) database collates information and evidence on known professional spam operations that have been terminated by a minimum of 3 Internet Service Providers for spam offenses.”
“100 Known Spam Operations responsible for 80% of your spam.
80% of spam received by Internet users in North America and Europe can be traced via aliases, addresses, redirects, locations of servers, domains and dns setups, to a hard-core group of around 100 known spam operations, almost all of whom are listed in the ROKSO database.”
ROKSO may be very useful for law enforcement, but the rankings by cloud.SpamRankings.net may be more directly useful in ejecting spam (whether from botnets or snowshoe) from your organization.
Includes rank, domain name, "Qty." (presumably number of spam messages), and Share percentage.
Includes rank, IP address (plus domain name from reverse DNS where available, "Qty." (presumably number of spam messages), Share percentage, Age (presumably when first seen for this appearance), and Duration in days (presumably time on list).
