Japan’s TwitCasting shuts down after detecting unauthorized access
Moi suspended TwitCasting on October 28 after finding signs of unauthorized access to the service’s servers.
The Japanese company detected a system problem at about 10:30 a.m.
and shut the service down around 10 minutes later.
TwitCasting lets people watch and broadcast live video from phones and computers, and has more than 40 million registered users.
Moi says it blocked the affected network and suspended the service to limit possible harm and investigate.
The company is checking how far the incident reached, but has not confirmed the cause or full details.
Restoring service will take considerable time, and Moi says it will reopen only after confirming the service is safe.
It plans to share updates through its official X account and the Tokyo Stock Exchange’s disclosure system while its corporate website is also offline.
TwitCasting was suspended after its operator, Moi, detected signs of unauthorized access to the service’s servers.
Moi said the service went offline at about 10:40 a.m. on October 28.
The company said restoring the service would take “a considerable amount of time.”
Moi is investigating the scope and cause of the incident and has not announced a restart date.
