Cloud9 coach Bok "Reapered" Han-gyu's Twitter account was taken over on Tuesday by a hacker who published private information, including Cloud9's competitive scrimmages, the team's South Korean account logins, personal chat logs, and contact information for several members of North American League of Legends teams.
The tweets from the account have since been deleted, and Cloud9 tells ESPN.com that the team is in contact with Twitter, Riot Games and Team SoloMid, whose private information was also leaked, to attempt to resolve the issue.
"Our Cloud9 accounts platform is already two-stepped," Cloud9 general manager Danan Flander said. "We are unsure how they have accessed our scrims or Reapered's Twitter. Most, if not all of our accounts, are on two-step. It is mandatory on the Cloud9 accounts platform, but we are not able to enforce it across our social platforms outside of notifying players, staff and personalities about its importance."
Former professional League of Legends player Marcel "Dexter" Feldkamp noted that Riot Games has urged its professional players to take advanced security measures:
That feel when Riot does a pro player summit and tells everyone how and why they should get 2 factor auth but noone does it

Flander confirmed that Riot communicates these warnings to players, including his team, but said neither Riot nor the Cloud9 organization can force players or staff to take these precautions.
