The World's Worst Spammers

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.

The 10 Worst Spammers
As of 29 July 2014 the world's worst spammers and spam gangs are:

1
Canadian Pharmacy - Ukraine
A long time running pharmacy spam operation. They send tens of millions of spams per day using botnet techniques. Probably based in Eastern Europe, Ukraine/Russia. Host spammed web sites on botnets and on bulletproof Chinese web hosting.

2
Yair Shalev / Kobeni Solutions - United States
High volume snowshoe spammer from Florida, (former?) partner-in-spam of ROKSO spammer Darrin Wohl. Son-in-law of ROKSO listed spammer Dan Abramovich. Sued by FTC in 2014 due to fraud.

3
Century Infotech - India
India based spammers-for-hire. They rent an endless number of servers to host their own spam webpages and the webpages of their spam-clients, such as the infamous "Flooring" spammers.

4
Jagger Babuin / BHSI - Canada
Romanian spammer now living in Vancouver BC. Also known as the "Dr Oz" spammer.

5
Michael Lindsay / iMedia Networks - United States
Lindsay's iMedia Networks is a full-fledged spam-hosting operation serving bulletproof hosting at high premiums to well known ROKSO-listed spammers. His customers spam via botnet zombies with spam payloads hosted offshore, tunneled back to his servers. He and the gang have been hijacking (stealing) IP address space from companies for years to spam from. Illegal in the USA.

6
Yambo Financials - Ukraine
Huge spamhaus tied into distribution and billing for child, animal, and incest-porn, pirated software, and pharmaceuticals. Run their own merchant services (credit-card "collection" sites) set up as a fake "bank."

7
First Place SEO & financial fraud spam gang - United States
Seem to be either Northern New Jersey or San Diego, California based scammers. They rent endless numbers of servers and buy endless domains to then pump out "SEO", search-engine-rankings and financial fraud scam spams.

8
Vincent Chan gang - Hong Kong
Vincent Chan and his Chinese partners have been sending spam for years. They mainly do pharmacy, and are able to send out huge amounts daily. They use vast numbers of compromised computers -- for sending, hosting and proxy hijacking. Now seem to be an "oursourced" server obtainer for other spam gangs.

Dante Jimenez / Aiming Invest - United States
Spamwarez, lists, "bulletproof" hosting in the finest South Florida tradition. Working with worst cybercriminal botnet spammers.
