Cyber-attack at Vodafone Portugal disrupts mobile network services

A “deliberate and malicious” cyber-attack targeting Vodafone Portugal disrupted mobile networks across the country this week.

The incident, which started on Monday evening (February 7), suspended 4G and 5G networks for customers, as well as digital TV and SMS services.

Vodafone said that there is no evidence of any data breach due to the attack.

Deliberate and malicious

In a statement, Vodafone Portugal blamed the outage on a “deliberate and malicious” cyber-attack.

It added: “Vodafone was the target of a network disruption that began on the night of February 7, 2022, because of a deliberate and malicious cyber-attack intended to cause damage.”

At the first detection of the problem on the network itself, Vodafone acted immediately to identify and contain the impact and restore services.

We have already recovered mobile voice services and mobile data services are available only on the 3G network in almost the entire country but, unfortunately, the scale and seriousness of the criminal act to which we were subjected implies careful and prolonged work for all other services.”, said Vodafone.

“The service is also subject to some limitations, namely with regard to the maximum speed allowed in order to ensure better monitoring of network usage, as well as a more fair and sustainable distribution of the capacity made available to our customers,” Vodafone said.

Vodafone said its cybersecurity team is working with authorities as it investigates the incident.
