Vodafone Portugal has suffered a massive cyberattack which has crippled vital services around the country. Reports began on February 7 when customers noticed the network appeared to be down. Vodafone’s Chief Executive later confirmed that the company had been the target of a “criminal act” which had left almost seven million people without phone signal. The attack caused downtime in the 4G and 5G, television services, voice calling and SMS capabilities of the network. It also caused many vital services that run over the network to stop, including some national ambulance and fire brigade services. Early security work aimed to restore 3G services to critical infrastructure and safeguard customer data.
