Japanese space agency spotted zero-day attacks while cleaning up attack on M365

The Japanese Space Exploration Agency (JAXA) discovered it was under attack using zero-day exploits while working with Microsoft to probe a 2023 cyberattack on its systems.

But the space org’s statement also revealed the discovery of malware found and removed by an actor other than Microsoft. And then there’s the mention of zero-day attacks in the last sentence of a section about countermeasures like closer network monitoring and improve remote access security the agency adopted.
