Eurofiber France disclosed a data breach it discovered late last week when hackers gained access to its ticket management system by exploiting a vulnerability and exfiltrated information.
Eurofiber France SAS is the French unit of the Eurofiber Group N.V., a Dutch telecommunications service provider that operates a fiber network of 76,000 km across the Netherlands, Belgium, France, and Germany.
The company specializes in providing digital infrastructure for businesses, rather than the consumer market.
No critical data impacted
The cybersecurity incident impacts only the French division of the group, the company says in the announcement, including its cloud division (ATE portal) and its regional Eurafibre, FullSave, Netiwan, and Avelia sub-brands.
In a press release, the company states that the impact is minimal for indirect sales and wholesale partners in France, as most of them rely on separate systems.
“In the first hours following detection, the ticketing platform and the ATE portal were placed under enhanced security, and the vulnerability was patched,” mentions Eurofiber France.
“Additional measures have been implemented to prevent any further data leaks and strengthen system security.”
Although the company said that banking details or other “critical data” stored on its other systems were not affected by this incident, it did not specify exactly what types of data were stolen, only mentioning that it would notify affected customers.
