Security News > 2022 > February > Vodafone Portugal 4G and 5G services down after cyberattack
Vodafone Portugal suffered a cyberattack causing country-wide service outages, including the disruption of 4G/5G data networks, SMS texts, and television services.
The cyberattack began last night with Vodafone calling the incident "a deliberate and malicious attack intended to cause damage."
The attack mostly affects the provisioning of services on the data network, including 4G/5G network, fixed voice, television, SMS, and voice/digital answering services.
Vodafone Portugal has over four million cellphone subscribers in the country, and another 3.4 million home and business internet customers, so the cyberattack has caused a large-scale problem.
While Vodafone has not disclosed details on the attack, researchers in the threat intelligence community have told BleepingComputer that they believe it was a ransomware attack.
Bleeping Computer has contacted Vodafone Portugal and the Vodafone Group with further questions but has not received a reply from either yet.
