On unauthorized access to a computing system at KEK

November 14, 2013

High Energy Accelerator Research Organization (KEK)

On November 1, 2013, unauthorized access was identified in the operation record of the log-in server for KEK’s super computer system, and KEK immediately suspended the users operation of its super computer system.

So far, no evidence has been identified for unauthorized system alteration or divulgence of personal or sensitive information.

An investigation is currently under way to determine the magnitude and extent of effects, if any. The investigation so far indicates that this incident involves unauthorized access to KEK’s computer by using user credentials which had been stolen in some fashion elsewhere. We are currently in the process of implementing countermeasures, including introduction of strengthened security-related set-ups, to prevent recurrence of similar incidents, and will resume service operation of the computer soon thereafter.

KEK expresses its regret to the users and members of organizations that have been affected by this incident.
