A Russian sports official earlier this year estimated[1] that as many as 2 million people would flock to the country during the World Cup[2], the month-long celebration of soccer—or football, fine—that kicks off today in Moscow. If you’re one of them, have fun! But also maybe leave your laptop at home.

And even if you’re just a fervent Finland fan, indiscriminate cybercrooks run rampant.

That may sound like hyperbole, but it’s also official guidance from the top counterintelligence official in the United States. “Anyone traveling to Russia to attend the World Cup should be clear-eyed about the cyberrisks involved,” William Evanina, director of the National Counterintelligence and Security Center, said in a statement this week. “If you’re planning on taking a mobile phone, laptop, PDA, or other electronic device with you—make no mistake—any data on those devices (especially your personally identifiable information) may be accessed by the Russian government or cybercriminals.”

“There’s a baseline level of untargeted cyberattack type stuff that happens in Russia, Ukraine, nearby places,” says Ryan Lackey, founder of ResetSecurity. “That ambient background level is fairly high, which also is cover for whenever there’s a targeted attack. So you’ve got an increased risk versus
