At the end of April, a series of continuous DDoS attacks hit Americas Cardroom (ACR), an online poker site and it’s Winning Poker Network (WPN), which continued until May 1. According to a series of ACR tweets, it was reported that the website will be under scheduled maintenance from 7 a.m. to 10 a.m. ET on Tuesday, but a later tweet revealed that ACR was under a DDoS attack forcing them to pause the tournaments.


This tweet brought outrage to many players and some requested reimbursements for the day’s tournaments. Users also accused ACR of lying about DDoS attacks, information security researchers said. However, the attacks continued until the next day (April 25). A new ACR tweet announced that all paused tournaments were canceled and players would be reimbursed accordingly.

From April 30 to May 1, ACR kept tweeting about continuous DDoS attacks, canceling and reimbursing the tournaments.

Information security professionals are not yet clear who is behind these massive DDoS attacks, it is clear that cyber attacks against the gaming industry are on the rise. Last September, Americas Cardroom suffered a series of massive DDoS attacks forcing the company to interrupt all ongoing tournaments. In this incident, the attacker demanded ransom from the company to stop attacking its servers.

Also, a few days ago, the world’s largest rental DDoS platform,, was closed and its administrators were arrested. The platform was also used to carry out cyber attacks in games and other high-profile industries.
