A cyber attack on Vodafone Portugal leaves 4 million customers without service

Vodafone Portugal has acknowledged this Tuesday that it has not yet managed to restore the service after a cyberattack that has affected nearly 4 million customers. According to the company, which has described the attack as a “terrorist act”, the personal data of users has not been affected.

The company’s executive director in the country, M├írio Vaz, explained that the attack occurred this Monday at 9:00 p.m. (local time) and has affected services based on data networks, mainly 4G and 5G, fixed voice, television , SMS and voice/digital answering machine. Vaz has admitted that he cannot say when those services will be restored to normal.

The company has important Portuguese clients, such as the National Institute of Medical Emergency (INEM), firefighters or banking entities, which have had to use the minimum services of Vodafone or resort to other companies in order to operate.

According to Vodafone Portugal, which has reported the cyberattack to the Portuguese Judicial Police, there is “no indication that there is access to or corruption of customer data.” “It is not an attack directed at the systems. It is an attack directed at the network with the purpose, surely voluntary, intentional, of leaving our clients without any service”, explained Vaz.

The Judicial Police has subsequently confirmed in a statement that it has opened a criminal investigation and has assured that it has made contacts with its international counterparts, without specifying which ones, “to collect more and better information.”

This attack occurs a month after the one perpetrated against Grupo Impresa, owner of the newspaper “Expresso” and the SIC channel.
