Internet activist group Anonymous is targeting Formula One once again.
Last month, the 'hacktivists' aimed fire at the sport over the Bahrain issue, bringing down the Formula One and FIA websites.
Anonymous is backing the protesting Montreal university students over the controversial 'Bill 78', a law that cracks down on their marches.
"Beginning on June 7 and running through race day on June 10, Anonymous will take down all the Formula 1 websites, dump the servers and databases, and wreck anything else Formula 1 related we can find on the internet," the group said in a statement.
The group also said spectators who buy tickets on the internet risk having their credit card details stolen.
Organisers of the Canadian Formula One Grand Prix did not comment.
