How to defend against Ransomeware

We hereby notify the impact and action to our devices against ransomeware (a type of malware) which has been widely publicized since the middle of May, 2017.

1. Impact on our devices
We are investigating followings.
(1) Possibility of infection on our devices
(2) Assumed malfunction when infected
(3) How to address when infected
We will let you know results upon completing the investigation.

2. Preventive action at customer
Isolating devices from the source of ransomeware, updating the system software and device application software to be invulnerable are required to avoid being infected. We are working on the latter by inspecting devices with updated Windows and by updating device application software. We recommend customers to take action for the former as shown below.
(1) If your devices are connected to network and its operator’s manual or related document requires you to disconnect from external network, make sure again that your devices follow requirements.
(2) When a PC is included in devices, do not connect other device such as USB memory to the PC since it may contain malware. But if connecting them is absolutely necessary, be sure to check them to see if they are not infected prior to connection.

3. When you find abnormality
When you encounter this threat, or you find any abnormal device operation which seems different from routine operation, immediately notify your distributor of abnormality.
Distributor’s sales/service staff will take an appropriate action. Action to be taken depends on operating status of devices.

Your cooperation is highly appreciated.
