Vodafone Portugal was hit by hackers on Tuesday, disrupting its services, though customers’ personal data was not compromised.
Vodafone Portugal in a statement said the systems faced technical problems on Monday evening. Many customers reported they were not able to make calls or access the internet on their phones or computers.
On further investigation, the reason behind the technical issues was a deliberate and malicious cyber attack.
Vodafone said, “There is no evidence customer data has been accessed or compromised,” it said. “An in-depth investigation of the criminal act…will continue for an indefinite period, with the involvement of the competent authorities.”
Earlier last month one of Portugal’s biggest newspapers and a major broadcaster were hacked and were unable to access their websites.
The attack on Vodafone came a month after the websites of one of Portugal’s biggest newspapers and of a major broadcaster were hacked. Both media organizations remain unable to access their websites.
Vodafone Portugal added, “determined to restore the normality of services” while the mobile communications were gradually recovering. 4G network users will not be able to access the service, while most of the users can use 3G for the time being.
