Lyca Mobile has suffered an unexpected disruption on its network caused by a cyberattack that may have also compromised customer data.
The British company provides voice IP (VoIP) and mobile telecommunications services in 60 nations, including the US, UK, Germany, Australia, France, Italy, and the Netherlands.
The attack occurred over the last weekend and caused service provision interruptions in almost all countries the telecommunication company operates in. Customers and retailers reported to Lyca that they were unable to access the company’s top-up portal.
As per the official statement, phone services on a national and international level have also been impacted. In response to the situation, and to determine the impact on customer data, Lyca Mobile says it launched an urgent investigation that involves external IT experts, law enforcement, and data protection authorities.
The business’s response about encrypted consumer data suggests that it has confirmed or has reason to believe that unauthorized access to its systems has occurred. The statement does not, however, specify the kind of encryption that is employed to safeguard consumer data.
Lyca Mobile added that it has restored mobile telecommunication services in all of its markets but said some unspecified operational services are still being restored.
