Japan’s Public Security Intelligence Agency has warned in its annual end-of-year report that cyber-attacks targeting next year’s Olympic and Paralympic Games in Tokyo are among the biggest threats the country faces.

In the report released regarding the security situation in Japan and overseas, the Agency claimed that cyber-attacks may interfere with Olympic operations as prior host nations have become targets of such attacks in recent years.

Earlier this week, Tokyo 2020 published a warning alerting of an ongoing phishing campaign delivering emails designed to look like they are coming from Japanese organizers.

“We have recently detected emails disguised to look like they are coming from a Tokyo 2020 staff member,” a warning message from Tokyo 2020 said.

“Although the email may look official and legitimate, if you have no reason to receive such an email or if the content is questionable, you should not click on the link or open any attached files.”
