Operation Ghost Click

The proprietors of shadowy online businesses that have become synonymous with cybercrime in recent years were arrested in their native Estonia on Tuesday and charged with running a sophisticated click fraud scheme that infected with malware more than four million computers in over 100 countries — including an estimated 500,000 PCs in the United States. The law enforcement action, dubbed “Operation Ghost Click,” was the result  of a multi-year investigation, and is being called the “biggest cybercriminal takedown in history.”

Estonian authorities arrested six men, including Vladimir Tsastsin, 31, the owner of several Internet companies that have been closely associated with the malware community for many years. Tsastsin previously headed EstDomains Inc. a domain name registrar that handled the registrations for tens of thousands of domains associated with the far-flung Russian Business Network.

Reporting for The Washington Post in September 2008, I detailed how Tsastsin’s prior convictions in Estonia for credit card fraud, money laundering and forgery violated the registrar agreement set forth by the Internet Corporation for Assigned Names and Numbers (ICANN), which bars convicted felons from serving as officers of a registrar. ICANN later agreed, and revoked EstDomains’ ability to act as a domain registrar, citing Tsastsin’s criminal history.
