"Vaulin is charged with running today's most visited illegal file-sharing website, responsible for unlawfully distributing well over $1 billion of copyrighted materials," said Leslie R. Caldwell, the assistant attorney general of the Justice Department's criminal division.
"In an effort to evade law enforcement, Vaulin allegedly relied on servers located in countries around the world and moved his domains due to repeated seizures and civil lawsuits. His arrest in Poland, however, demonstrates again that cybercriminals can run, but they cannot hide from justice," the statement read.
KAT operates in approximately 28 languages, according to the complaint.
KAT's net worth has been estimated at more than $54 million, with estimated annual advertising revenue in the range of $12.5 million to $22.3 million, according to the complaint.
KAT has moved its domain several times due to numerous seizures and copyright lawsuits, and it has been ordered blocked by courts in the United Kingdom, Ireland, Italy, Denmark, Belgium and Malaysia, the complaint states. The statement added that the website's value is estimated at a tune of more than 54 million dollars with its advertising revenue in the range of 12.5 million dollars and 22.3 million dollars.
The website has been seized and has gone offline for the moment.
