Nikkei Discloses Two Employee Cloud Account Compromises
Nikkei says two employee cloud accounts were hijacked, exposing contacts and sending about 9,000 phishing emails.
Japanese publisher Nikkei disclosed that an employee Google Workspace account was accessed externally from late July, potentially exposing names and email addresses of 1,646 employees, partners, and others. A separate Microsoft 365 account was used on September 30 to send about 9,000 emails directing recipients to malicious sites, and some mailbox content may have been exposed. Nikkei reset both passwords, reported the cases to Japan’s Personal Information Protection Commission, and has not said how the accounts were compromised. Group unit Nikkei BP also reported a September 30 phishing-led mailbox compromise affecting 26 contacts, after a 2025 Slack breach tied to infostealer-stolen credentials exposed 17,368 people.
