Sega's mobile game "Chain Chronicle" (Japanese server) has entered long-term emergency maintenance due to system security issues. Officials estimate that investigation and repairs may take one to two months in total, with no confirmed date for service restoration at this time.
After the PHP team recently released patches for two critical vulnerabilities, the operations team began inspecting the game application and servers. Following an investigation lasting about a week, officials confirmed security issues in some systems. However, as of the announcement, no illegal logins or information leaks have been detected.
Further assessment indicates that simply updating the affected local systems is insufficient to completely eliminate risks, and the game application may require extensive modifications. Officials estimate the investigation phase will take about a month, with subsequent repairs likely requiring a similar amount of time. The actual completion date remains subject to change based on progress.
The radio program "Chenraji" will continue to air. Episode 492, scheduled for release on November 2nd, will feature Director Matsunaga and Producer Tomomitsu providing another update on the current situation. The operations team will also share updates on response measures and the estimated recovery time through subsequent announcements.
