SFR

Altice, alsoknown as SFR Group, operates as a telecommunications operator that provides mobile voice and data services, sells smartphones and associated RED plans, and manages customer orders through a dedicated order‑management tool. In addition to its mobile offerings, the organization functions as an internet service provider, delivering broadband connectivity to customers in several Western European countries. It conducts business under a range of brand names including Altice, SFR, Altice Europe, Altice France, and the historic Société Française du Radiotéléphone, with its headquarters located in France.

Public sources do not disclose specific quantitative metrics such as subscriber count or revenue, so the exact scale of the organization remains unspecified in the available material. However, references to its involvement in distributed denial‑of‑service incidents indicate that it provides services in Belgium, France, and the Netherlands, showing a cross‑border footprint within the European ISP landscape. The organization’s presence in these markets is confirmed by reports of DDoS attacks targeting its DNS infrastructure alongside other regional providers.

The organization’s distinguishing attributes include its experience with large‑scale DNS‑focused DDoS attacks that employed amplification and LDAP vectors reaching hundreds of gigabits per second, highlighting its role in critical internet infrastructure. It has also been the target of a ransomware attack by the Hive group on its financial holding division, demonstrating exposure to sophisticated cyber threats beyond its core network operations. A separate incident involved unauthorized access to a customer order‑management tool, resulting in the exfiltration of personal data such as names, contact details, order information, IBANs, device identifiers and SIM numbers, prompting the company to strengthen authentication procedures, notify regulators, file a legal complaint and open a helpline for affected customers. These events collectively illustrate the organization’s focus on both telecommunications services and the associated security challenges of handling sensitive customer and financial data.

Structurally, the French operations conducted under the SFR brand constitute a subsidiary of the broader Altice group, which also encompasses a financial holding division that was singled out in the ransomware episode. The organization operates under multiple legal aliases that reflect its corporate evolution and geographic focus, while maintaining a central headquarters in France. No further details about parent‑company ownership or additional subsidiaries are provided in the source material.
