Nikkei Discloses Cyberattack on Journalistic Sources

Japanese media group Nikkei disclosed two cyber incidents involving employee email accounts on Sunday. An attacker compromised a Microsoft 365 account to send roughly 9,000 phishing emails targeting people who had previously communicated with Nikkei employees. The breach may have exposed recipients' names and email addresses, as well as the contents of some emails. Nikkei reported the incident to Japan's data protection authority and is still determining how many people had their personal information compromised.
