Vodafone Portugal telecom services disrupted by a cyber attack

This morning, the Portuguese unit of telecommunications company Vodafone confirmed that a hacking group disrupted its services overnight Monday, in what appears to be a failed attempt to access its customers’ personal data. In its statement, the company said the technical issues caused thousands of customers to suffer disruptions to their phone call services and Internet access. Later, it was confirmed that the outages were triggered by a “malicious and deliberate” cyber attack.

The good news is that, so far, the company has not identified indications of access to or compromise of its customers’ confidential information, although the investigation is still ongoing: “The in-depth investigation will continue indefinitely with the participation of the competent authorities,” the company notes.

This incident comes a month after the hacking of the websites of one of Portugal’s largest newspapers and a major broadcaster was confirmed; to date, both media organizations remain unable to access their websites.

Finally, Vodafone Portugal said its teams are determined to restore all affected services, as well as confirming that phone call systems were already in the process of recovery. The 4G network is still unavailable but customers in most parts of the country can still turn to the use of 3G technology.

The company did not add further details about the attackers and the possible hacking variants used during the attack.
