Oomiya

Oomiya, also known as Oomiya, is a Japanese technology firm headquartered in Japan. The company specializes in microelectronics and facility system equipment. Its product portfolio includes components and systems used in semiconductor manufacturing, automotive electronics, communications infrastructure, and healthcare devices. Oomiya supplies these technologies to manufacturers and integrators operating in domestic and international markets. The firm’s focus on precision microelectronics positions it within the supply chain of high‑tech industries.

In October 2022, Oomiya was targeted by LockBit 3.0 ransomware affiliates, who claimed to have exfiltrated company data and threatened to leak it unless a ransom was paid. The incident highlighted the firm’s role in critical sectors such as semiconductors, automotive, communications, and healthcare, underscoring potential supply‑chain repercussions. Although no verified samples of the alleged stolen data were publicly released at the time, the attack drew attention to the cyber‑risk landscape facing Japanese technology suppliers. The attack occurred during a period of heightened activity by LockBit affiliates, reflecting broader ransomware trends at the time. Oomiya continues to operate as a provider of microelectronics and facility system solutions following the incident.
