The Japanese video-sharing platform, Niconico, was forced to suspend its services following a cybersecurity incident.

The Japanese video-sharing platform, Niconico, temporarily suspended its services following a large-scale cyberattack on June 8, 2024.

“Due to the effects of a large-scale cyber attack, Niconico has been unavailable since early morning on June 8th” reads the incident notice published by the company. “We sincerely apologize for the inconvenience.”

In response to the incident, the company temporarily suspended Niconico Family Services such as Niconico Video, Niconico Live Broadcast, Niconico Channel, etc. The company also suspended the Niconico Account login on external services.

“Beginning in the early hours of Saturday, June 8th, an issue occurred that prevented access to multiple servers in our group. In response to this incident, we immediately shut down the relevant servers to protect the data. Based on the scope of our internal analysis and investigation that was conducted on the same day, we have determined that there is a high possibility that we were the victim of a cyber attack.” reads a statement from the company.

The video-sharing platform also canceled/postponed programs scheduled from June 10th to June 16th.

The company is investigating the security incident with the help of law enforcement and external experts to determine the full extent of the damage.

The company has yet to determine if threat actors have stolen any information from its systems.

The Japanese firm did not reveal the type of cyberattack it suffered; however, the problems it is facing and the incident response procedure adopted suggest it was the victim of a ransomware attack.
