French telecommunications leader Orange has announced that it filed a formal complaint on Monday, July 28, 2025, following a cyberattack detected on one of its information systems, marking the latest in a series of cybersecurity incidents targeting major European infrastructure companies.
Security Incident Detection and Response
Orange first detected the cyberattack on Friday, July 25, 2025, prompting immediate mobilization of security teams across the organization.
The company’s cybersecurity division, Orange Cyberdefense, provided crucial support as teams worked swiftly to isolate potentially affected services and minimize the impact of the breach.
This rapid response demonstrates the telecommunications giant’s commitment to maintaining robust cybersecurity protocols in an increasingly hostile digital landscape.
The security incident required Orange to implement precautionary isolation measures across multiple systems, which inevitably disrupted normal operations for many customers.
These protective measures particularly affected Enterprise clients and several Public services, with disruptions concentrated primarily in France, where Orange maintains its largest operational footprint.
The company’s dedicated customer service teams have been fully mobilized to inform and support affected clients throughout the incident response process.
Service Restoration and Recovery Timeline
Orange’s technical teams have identified comprehensive solutions that enable the gradual reopening of impacted services under enhanced security vigilance.
The company announced that it expects to restore the majority of affected services by Wednesday morning, July 30, demonstrating the effectiveness of its incident response capabilities.
This timeline reflects Orange’s commitment to balancing security concerns with service continuity for millions of customers across Europe and Africa.
The systematic approach to service restoration highlights Orange’s mature cybersecurity infrastructure and well-established incident response protocols.
Teams continue working around the clock to ensure all systems meet heightened security standards before being brought back online.
Investigation Status and Data Protection
Orange has maintained full cooperation with competent authorities following the filing of their formal complaint.
The company emphasized that current investigations have revealed no evidence suggesting that customer data or internal Orange information was exfiltrated during the security incident.
This reassurance comes as data protection concerns continue to dominate public discourse around cybersecurity breaches affecting major telecommunications providers.
The telecommunications giant maintains the highest level of vigilance regarding potential data compromise, reflecting industry best practices for incident response and customer protection.
For security reasons, Orange has stated it will not provide additional comments beyond its official announcement, a standard practice designed to protect ongoing investigations and prevent further security vulnerabilities.
This incident underscores the continuing challenges facing major telecommunications providers in protecting critical infrastructure against sophisticated cyber threats targeting essential services across Europe.
