株式会社タカミヤ

株式会社タカミヤ, also known as Takamiya Co., Ltd., is headquartered in Japan. The company maintains a branch in Vietnam, as indicated by the origin of a cybersecurity incident. It operates under the legal name Takamiya Co., Ltd. and is recognized by its Japanese alias.

On December 15, 2022, Takamiya Co., Ltd. experienced unauthorized server access and a ransomware attack carried out by the LockBit group, which originated from its Vietnam branch. The attack resulted in the encryption of files and raised concerns about potential exposure of customer information and employee details across the group. Although three of its subsidiaries confirmed that no personal data was leaked, the incident prompted the company to establish an internal response team. Recovery efforts were initiated, and external cybersecurity experts were engaged to assist with remediation. The organization reported the incident to relevant regulatory authorities and law enforcement agencies. Subsequently, the attackers listed Takamiya Co., Ltd. on a leak site, leading to dark web monitoring and forensic investigations. These actions were undertaken to determine the full scope of impacted data and to understand the intrusion methods used. The company's response included ongoing monitoring to mitigate further risk.
