Warning: NISC Impersonation Scam Phone Calls Demanding Money
Summary
NISC (Japan's National Center of Incident Readiness and Strategy for Cybersecurity) has issued a public warning about an active phone scam in which fraudsters impersonate NISC and the National Cybersecurity Center (NCO), demanding money from individuals under false pretenses of cyberattack-related settlement fees, compensation, or insurance premiums. The scammers frequently rotate between posing as telephone companies, police, and lawyers to add credibility, and instruct victims not to discuss the calls with anyone. NISC explicitly states it never makes such telephone contact. The agency advises anyone receiving suspicious calls or who has been victimized to contact their nearest police station.

What changed
NISC issued a consumer protection alert notifying the public of a specific type of impersonation fraud targeting Japanese residents. The fraud involves callers misrepresenting themselves as NISC or NCO staff and demanding payment for fabricated cyberattack-related costs. NISC confirmed it does not contact the public by telephone for these purposes. The alert provides no regulatory obligations or compliance deadlines — it is purely an informational public safety notice.
Organizations and individuals operating in Japan should be aware that NISC has formally disavowed any outbound telephone contact requesting money. Any such call is a criminal impersonation. Consumers who receive these calls should not comply with payment demands and should report the matter to local police as instructed in the notice.
What to do next
- If you receive a suspicious call impersonating NISC or NCO, or if you have been victimized, contact your nearest police station to report or seek advice.
