Data Stolen in Eurofiber France Hack

European fiber optic network operator Eurofiber over the weekend announced that a threat actor has compromised its ticket management platform and the ATE customer portal.

The incident, the company says, occurred on November 13 and resulted in a data breach. The hackers exploited a vulnerability that allowed them to exfiltrate data stored on the affected platforms.

The impacted ticket management platform is used by Eurofiber France and its regional brands Avelia, Eurafibre, FullSave, and Netiwan. The ATE customer portal is used by Eurofiber Cloud Infra France, which is Eurofiber France’s cloud division.

According to the company, the data breach affected only customers of Eurofiber France and its subsidiaries, and did not impact Eurofiber customers in Belgium, Germany, or the Netherlands.

“For indirect sales and wholesale partners in France, the impact is very limited, as most use separate systems,” Eurofiber said in an incident notice on its website.
