Profile
CIS, also known as CIS, is headquartered in Japan. The organisation operates servers and client devices that support its internal and external network activities. It maintains an online presence through its domain cisjp.com, where it publishes news and updates. The organisation’s name appears in the URL of its official news site.
On June 25, 2023, CIS experienced a cybersecurity incident in which unauthorized external actors gained access to one of its servers using ransomware. The ransomware encrypted internal data and led to the confirmed exfiltration of personal and corporate information held by the organisation. In response, CIS disconnected all servers and client devices from both internal and external networks to contain the breach.
The full scope of the incident was not immediately determined, as the investigation was expected to require additional time to assess the extent of data loss and identify any further compromised systems. CIS has indicated that it is working with relevant authorities and cybersecurity experts to remediate the impact and strengthen its defenses. The incident was reported via CIS’s own news channel and covered by cybersecurity‑jp.com.
