Joc Hacked In April 2020
It has been revealed that the Japanese Olympic Committee suffered a cyberattack in April last year, but did not publicly disclose the incident as there was no sign of a data leak.
The JOC says it was forced to temporarily halt operations after PCs and servers at its office in Tokyo were infected with malware. It says data stored in the servers were tampered with, and access was blocked.
Officials say computer security experts who probed the incident suspect it was a ransomware attack, but there were no demands for money.
They add that the experts found no sign of a data leak. Personal information on Olympic hopefuls from various sport federations was stored in the servers.
The JOC says it spent about 30 million yen, or about 270,000 dollars, to replace about 70 percent of the roughly 100 PCs and servers due to suspected infection.
JOC Senior Executive Board Member Momii Keiko said the organization did not disclose the incident to sport federations and other relevant parties because there was no likelihood of a data leak that might affect them.
Momii also said the JOC did not want people to think that its servers were vulnerable. She added that it did report the incident to the Sports Agency, consulted experts and responded in line with the rules.
