What happened
ownCloud recommended enabling MFA after credential theft reports. Attackers exploited reused passwords and unprotected accounts to gain unauthorized access. The threat impacts both on-premises and cloud deployments, particularly for users managing sensitive documents and internal collaboration data.
Who is affected
ownCloud users, including enterprises with document management workflows, face direct exposure; indirect risk exists for connected systems.
Why CISOs should care
Credential theft can lead to data exfiltration, unauthorized sharing, and regulatory violations.
3 practical actions
Enable MFA: Require multi-factor authentication for all ownCloud accounts.
Audit account logins: Track unusual logins or geographic anomalies.
Enforce password hygiene: Require strong, unique passwords and regular rotation.
