What to do

Consult JAXA's official notice for affected-party communications and response context. It describes faster vulnerability response, stronger monitoring, and impersonation defenses, but does not provide a specific CVE patch or universal VPN-replacement mandate.

What happened

JAXA considers exploitation of a previously disclosed VPN vulnerability likely, without naming a CVE. It separately reports 2024 intrusions, including zero-day attacks, with no information leakage confirmed from those events. Sensitive rocket and satellite operations information was not handled on the affected systems.
