Japanese video game developer Capcom said it has suffered a cyber-attack that impacted some of the company’s business operations, including email and file servers.

The incident, which took place on early hours of November 2, involved an unauthorized access carried out by a third party, the company said. Due to the cyber-attack some operations of the Capcom’s internal network have been halted, but the company said that there is no evidence that any customer information has been compromised.

“This incident has not affected connections for playing the company's games online or access to its various websites,” the company stated.

While Capcom did not provide information on the nature of the cyber-attack, sources have told BleepingComputer that Capcom suffered a TrickBot infection in August, which usually leads to Ryuk or Conti ransomware attacks.
