The United States has seized nearly ‌400 internet domains that were being used to illegally stream the World Cup, officials said on Friday, describing the move as one meant to disrupt international networks profiting from the popularity of ‌the tournament.

The Department of Justice said the ​domains were identified with the assistance of soccer governing body FIFA and others, including NBC Universal ⁠and Warner Brothers.

The domains were used to illegally offer ​users copyright-protected content in the form of real-time streams ⁠of the World Cup matches as they were being played and first broadcast, the department said.

"These streamers not only violate copyright laws but ‌also expose viewers to potential threats — including malware ​attacks and unsecure ‌connections that can compromise personal and financial data," Eric Weindorf, a special ‌agent in charge at Homeland Security Investigations, said in a statement.

Servers and domains linked to the unauthorized streaming of ⁠the tournament's matches were ‌targeted in Peru and ⁠Bulgaria, the DOJ said, adding that additional disruptions took place in ⁠Croatia, Romania, ⁠Poland and Colombia.

The World Cup kicked off June 11 in the United ‌States, Canada and Mexico. Games are scheduled to be played in 16 cities across the three countries through July 19.

Attendance ‌for the ​matches have set ‌records, according to FIFA. Last week's matches were some of the most watched television programs, ​according to Nielsen. The United States' victory over Australia topped that list.
