Orange Detects Cyberattack on July 25

French telecommunications leader Orange announced on Monday that one of its information systems was hit by an unspecified cyberattack on July 25.

Upon detection, the company promptly isolated potentially affected services to contain the breach, aiming to minimize any adverse impact on its network.

These containment measures led to disruptions across several customer platforms, affecting business clients and public sector services primarily in France.

Orange reassures that restoration efforts are underway and expects full service recovery by Wednesday, with no current evidence of internal or customer data exfiltration.

Restoration and Regulatory Response

The telecom plans to implement phased solutions to bring all platforms back online while continuously monitoring for any security anomalies.

In compliance with GDPR, Orange has filed a complaint with relevant authorities and is notifying all affected customers within the required three-day window.
