LISBON, Feb. 8 (Xinhua) -- A cyberattack on Vodafone Portugal, one of the country's leading telecommunications companies, has affected four million customers on Tuesday.
The victims include essential services such as the post office, firefighters and the National Institute of Medical Emergency (INEM).
According to Vodafone Portugal, it was a "targeted attack on the network," which aimed to "cause damage and disturbance."
Access to 3G voice and data services has already been restored, but business and banking services are still inaccessible, said Mario Vaz, chief executive officer (CEO) of Vodafone Portugal.
According to the company, the attack started late on Monday and reached a "severity level that made the recovery of services as difficult as possible." It caused the "abrupt interruption" of almost all services.
According to Vaz, Vodafone Portugal continues to cooperate with the Judicial Police to investigate the attack and its origins. "There are no indications of customer data breach," he said.
Vodafone's competitors have offered to help in restoring the company's services. ■
